See all travel eSIMs by region on Destinations.Before you start: quick checklistiPhone 16 running iOS 18 (Settings > General > Software Update).Unlocked device (check with your home carrier if you bought it subsidised).Stable Wi‑Fi or a strong mobile connection for activation.eSIM details from your provider: QR code or SM‑DP+ server, activation code and (if provided) confirmation code.Power above 20% (or connect to a charger).Keep your original SIM/eSIM active until your travel eSIM is confirmed working (for any verification SMS).Pro tip: Take a screenshot or print your eSIM QR code before you fly. Airports Wi‑Fi can block email links or carrier portals.How to add an eSIM on iPhone 16 (iOS 18)All methods start in the same place.1) Open Settings2) Tap Mobile Data (Cellular)3) Tap Add eSIMOn iOS 18 you’ll typically see options like: - Use QR Code - Use Carrier/App - Transfer From Nearby iPhone (Quick Transfer) - Enter Details ManuallyOption A: Scan a QR code (fastest for most travellers)1) Go to Settings > Mobile Data (Cellular) > Add eSIM.2) Choose Use QR Code and point the camera at the code.3) When your plan appears, tap Continue > Add eSIM.4) Wait for “Activating…” then “Mobile Plan Added”.5) Assign a label (e.g., “Travel – Spain”) and set your default lines.What you’ll see: - “Activating…” progress bar- “Turn On This Line” toggle- “Set Default Line” and “Set Default for Data”Pro tip: If the scan fails, tap Enter Details Manually and type the SM‑DP+ server and Activation Code exactly as provided (case sensitive).Option B: Enter details manually (SM‑DP+)1) Settings > Mobile Data (Cellular) > Add eSIM > Enter Details Manually.2) Type the SM‑DP+ address, Activation Code and optional Confirmation Code.3) Tap Next and wait for activation to complete.Manual entry is useful if: - Your QR code is on another phone you can’t scan.- The camera won’t recognise the code under low light.- You’re adding a plan while offline (you’ll still need connectivity to complete activation).Option C: Add via carrier/provider app1) Install your provider’s app from the App Store.2) Purchase/select a plan, then choose Install eSIM in-app.3) Approve the eSIM install when iOS prompts you.4) Follow the same labelling and default line setup.Pro tip: If the app says “Installed” but you don’t see the plan, go to Settings > Mobile Data (Cellular) and look under Mobile Plans. If it’s listed but Off, tap it and enable Turn On This Line.Option D: eSIM Quick Transfer from your old iPhoneIf you’re moving your existing number from an older iPhone:1) Keep both iPhones nearby, unlocked, with Bluetooth on.2) On your iPhone 16, go to Settings > Mobile Data (Cellular) > Add eSIM.3) Choose Transfer From Nearby iPhone.4) Approve the transfer on your old iPhone and follow prompts.Notes: - This moves the plan; it usually deactivates on the old device.- Some carriers require re‑verification or a new QR. If transfer fails, contact your carrier.Set up dual‑SIM for travel (keep your number, use local data)Once your travel eSIM is added, optimise your settings:1) Label your lines- Settings > Mobile Data (Cellular) > Your Plans > Label (e.g., “Primary – UK” and “Travel – EU”).2) Choose default line for calls/messages- Settings > Mobile Data > Default Voice Line.- Pick Primary to keep your usual caller ID while roaming.3) Set data to the travel eSIM- Settings > Mobile Data > Mobile Data (Cellular Data).- Select your Travel eSIM.- Enable Data Roaming for the travel eSIM only.4) Stop bill shock on your home line- Tap your Primary plan > turn off Data Roaming.- Leave it On for calls/SMS only (or disable the line if you won’t use it).5) Allow “Cellular Data Switching” (optional)- If enabled, iPhone can briefly use Primary for data if your travel eSIM drops.- Travellers often keep this Off to avoid accidental roaming charges.6) iMessage and WhatsApp- iMessage: Settings > Messages > Send & Receive > tick your preferred number and Apple ID.- WhatsApp: linked to your account; it keeps working over your travel eSIM data.7) Network options- Settings > Mobile Data > Travel eSIM > Voice & Data: try 5G Auto first; switch to 4G/LTE if coverage is patchy.- Network Selection: leave Automatic On unless your provider advises a specific network.8) Personal Hotspot- Many travel eSIMs allow tethering. Check your plan.- Settings > Personal Hotspot to enable.Pro tip: Data‑only eSIMs won’t support normal calls/SMS. Use your Primary for voice/SMS, and use apps (WhatsApp/FaceTime/Teams) over the travel eSIM data.Top 10 activation errors on iPhone 16 (iOS 18) — and how to fix them1) “Unable to complete cellular plan change”- Toggle Airplane Mode On/Off, then retry.- Reboot the iPhone.- Try a different Wi‑Fi network (avoid captive portals).- Update carrier settings: Settings > General > About (wait for a prompt).2) “Activation failed” or “Could not activate eSIM”- Confirm the phone is unlocked.- Check date/time are automatic.- Enter SM‑DP+ and activation code manually.- Contact your provider to reissue the QR or refresh the profile.3) “This code is no longer valid” / “eSIM already in use”- Many QR codes are single‑use. Ask your provider for a new one.- If you deleted the plan, you may still need a fresh QR to reinstall.4) “Cellular plans from this carrier cannot be added”- Your carrier may not support eSIM on this device or market.- Confirm regional support or switch to a compatible travel eSIM.5) “No Service” / “SOS Only” after install- Turn Data Roaming On for the travel eSIM.- Settings > Mobile Data > Travel eSIM > Network Selection > Automatic (or pick the advised network).- Try 4G/LTE instead of 5G Auto.- Restart the iPhone.6) eSIM added but no data- Confirm Mobile Data is set to the travel eSIM.- Check APN settings if your provider supplied them (Settings > Mobile Data > Travel eSIM > Mobile Data Network).- Disable any VPN/Private Relay temporarily.7) “Invalid SM‑DP+ address”- Re‑type carefully; avoid extra spaces.- Ensure you’re using the activation code for the correct plan/region.8) Quick Transfer times out- Keep both phones on Wi‑Fi with Bluetooth enabled, screens unlocked.- Move them closer.- If it keeps failing, request a QR from the carrier instead.9) Stuck on “Activating…”- Wait 2–3 minutes; don’t exit the screen immediately.- Toggle Airplane Mode; then retry.- Reboot; try another Wi‑Fi network.- Update iOS and carrier settings.10) “Plan cannot be added” on eSIM‑only models- You may have reached the maximum stored profiles. Delete an unused plan: Settings > Mobile Data > tap plan > Remove eSIM.- Then add the new plan again.If you still can’t activate, capture the error wording and EID (Settings > General > About > EID) and contact your provider’s support—those two details speed up a resolution.Quick fixes that solve most issues (do these in order)1) Refresh radios: Airplane Mode On (10 seconds) > Off.2) Reboot the iPhone.3) Update iOS and carrier settings (Settings > General > Software Update, then Settings > General > About).4) Toggle the line Off/On (Settings > Mobile Data > tap plan > Turn On This Line).5) Set the travel eSIM as Mobile Data line and enable Data Roaming.6) Switch Voice & Data between 5G Auto and LTE to force re‑registration.7) Reset Network Settings (Settings > General > Transfer or Reset > Reset > Reset Network Settings).8) Try a different Wi‑Fi network for activation (or disable Wi‑Fi and use mobile data if available).Pro tip: Don’t remove the eSIM unless support advises it. Many plans can’t be reinstalled without a new QR code.Regional picks for common tripsUSA trip: choose Esim United States for coast‑to‑coast coverage.Canada + USA: go with Esim North America.Multiple EU countries: use Esim Western Europe.Single‑country Europe: Esim France, Esim Italy, Esim Spain.Browse every region and country: Destinations.Teams and frequent travellers: centralise plans and billing via For Business. Travel agencies and resellers can find tools in our Partner Hub.Expert traveller tipsInstall before you fly so you can test on home networks.Keep Primary for calls/SMS; use travel eSIM for data to avoid roaming charges.Turn off Wi‑Fi Assist (Settings > Mobile Data) if you don’t want surprise data use on the wrong line.Save your eSIM QR and plan info offline (Files app) for airports without reliable Wi‑Fi.If data is slow, switch to LTE—many destinations still have broader 4G coverage than 5G.After landing, toggle Airplane Mode Off/On once to force quick network registration.If you replace your iPhone mid‑trip, you’ll almost always need a new QR from your provider.FAQs1) How many eSIMs can iPhone 16 store and use at once?iPhone 16 can store multiple eSIM profiles (typically eight or more, carrier‑dependent) and use two lines at the same time. You can keep many plans saved and switch which one is active for data.2) Do I need Wi‑Fi to activate an eSIM?Wi‑Fi is best, but strong mobile data can also work. Avoid captive Wi‑Fi (airport/hotel login pages) during activation; tether from another device if needed.3) Can I keep my normal number for calls while using a travel eSIM for data?Yes. Set your Primary as Default Voice Line and your travel eSIM as Mobile Data. Turn off Data Roaming on the Primary to avoid charges, and leave Data Roaming On for the travel eSIM.4) Will iMessage and WhatsApp still work?Yes. iMessage uses the settings under Send & Receive; you can keep your usual number and Apple ID. WhatsApp works over whichever line provides data.5) Can I reuse or move an eSIM to another phone?Most travel eSIMs are single‑device and non‑transferable once installed. If you switch phones, you’ll usually need a new QR code from your provider.6) My iPhone 16 doesn’t have a SIM tray—can I still get my number onto it?Yes. Use eSIM Quick Transfer from your old iPhone or request a carrier eSIM/QR to convert your physical SIM to eSIM.Remove or pause an eSIM (when the trip is over)To pause: Settings > Mobile Data > tap the travel plan > Turn On This Line (toggle Off).To delete: Settings > Mobile Data > tap plan > Remove eSIM (you cannot usually reinstall without a new QR).Pro tip: Keep the line toggled Off for a future trip if your plan hasn’t expired and supports reactivation in the same region.The bottom lineOn iPhone 16 with iOS 18, adding a travel eSIM takes minutes and gives you local‑rate data without touching your primary number. Install via QR (or Quick Transfer), set your travel eSIM for data, and use the error‑fix list above if activation stalls. Ready to pick a plan for your route?

10-Day Europe Itinerary: France–Italy–Spain with One eSIM
Planning a Europe itinerary 10 days long that hits France, Italy and Spain is absolutely doable—if you keep the route tight and the logistics simple. This guide gives you a realistic, high-speed-train-first plan from Paris to Lyon to Milan and Rome, a taste of Florence, and a finale in Barcelona. You’ll carry one regional eSIM the whole way, so your maps, tickets and translators work across borders without swapping SIMs or hunting Wi‑Fi. Expect 2–3 hours on trains most move days, one short flight at the end, and well-paced city time where it matters. We’ve included setup steps for your eSIM, the right roaming toggles, typical 4G/5G speeds by city, and pro tips to keep things moving. If you need deeper country specifics, see our France, Italy and Spain eSIM guides linked throughout.Route at a glance (map this line on your phone)Day 1–3: Paris, France (arrive CDG/ORY) Day 4: Lyon, France (TGV from Paris, ~2h) Day 5: Milan, Italy (Frecciarossa from Lyon Part‑Dieu, ~5h15) Day 6–7: Rome, Italy (Frecciarossa from Milan, ~3h10) Day 8: Florence, Italy (Frecciarossa from Rome, ~1h35) Day 9–10: Barcelona, Spain (morning flight from Florence or Rome, ~1h45; final night and departure)Why this works: - You travel mostly by direct high‑speed trains. - Only one short flight (Italy to Spain) to avoid a 12–14 hour overland slog. - Big‑city anchors with one smaller-city palate cleanser (Lyon and Florence).For more country picks or alternates, browse Destinations.One eSIM for three countries (Western Europe plan)Use a single regional plan that roams seamlessly across borders. The Esim Western Europe option covers France, Italy and Spain on major networks with automatic network selection. You keep the same QR/profile the entire trip.Suggested data allowance for 10 days: - Light user (messaging, maps, email): 5–8 GB - Moderate (social, a few video calls, city navigation): 10–15 GB - Heavy (HD streaming, frequent tethering): 20+ GBCountry-specific tips and network notes: - France: Orange, SFR, Bouygues, Free Mobile are common. See Esim France for city nuances and coverage quirks. - Italy: TIM, Vodafone, WindTre, Iliad.

Paris Speed Test (Q4 2025): CDG Airport vs City Center vs Hotel Wi‑Fi
Heading to Paris and wondering if your phone or hotel Wi‑Fi will keep up? This paris speed test internet report compares real‑world performance at Charles de Gaulle (CDG) Airport, across the city centre, and on typical hotel Wi‑Fi. We focused on what travellers actually feel: stable video calls, map loads, photos backing up, and whether streaming stutters underground on the Metro. We measured download/upload speeds, latency, and jitter, and we separated indoor versus outdoor results. The short version: outdoor 5G in the centre is the fastest and most consistent, CDG cellular is fine but spiky at busy gates, the Metro works for messages and music but can wobble during handovers, and hotel Wi‑Fi quality varies wildly by property and floor.We’ve published an open CSV so you can audit or remix the dataset. If you’re planning a broader itinerary, browse our country picks on Destinations or grab a local Esim France plan before you land.TL;DR results at a glanceCity centre (outdoor 5G): median 180–260 Mbps down, 18–35 Mbps up; latency 18–30 ms; jitter 4–9 msCity centre (indoors near window): median 70–120 Mbps down; jitter rises to 8–15 ms in older buildingsCDG Airport cellular (landsid/airside): median 45–90 Mbps down, 8–15 Mbps up; latency 28–45 ms; jitter 8–18 msCDG Airport public Wi‑Fi: highly variable, typically 10–40 Mbps down, jitter >20 ms during peaksParis Metro snapshot: platforms 60–110 Mbps down; in‑tunnel 25–60 Mbps down; jitter spikes during cell handoversHotel Wi‑Fi: budget/mid‑range median 20–60 Mbps down with jitter 15–35 ms; premium/business floors often 100–250 Mbps down, jitter 6–12 msInterpretation: for calls and uploads, latency and jitter matter more than raw speed. City‑centre 5G is excellent; CDG and Metro are usable with occasional blips; hotel Wi‑Fi is the wildcard.How we tested (transparent methodology)Dates and windows: three days in Q4 2025 (morning, lunchtime, evening, and late night runs)Zones: CDG Terminals 1/2 (arrivals halls, selected gates, RER entrance), central Paris (1st, 2nd, 9th, 11th), and two hotels (one mid‑range, one upscale)Indoors vs outdoors: repeated runs on pavements, inside cafés, lobbies, and hotel rooms (window vs corridor side)Mobile tech: 5G NSA/SA and LTE where 5G unavailableDevices: recent iOS and Android flagships with eSIM; laptop for Wi‑Fi validationTools: two independent speed test engines; concurrent ping to EU anycast; jitter measured as latency variance over 30–60 secondsMetrics recorded: timestamp, coordinates (3‑digit geohash), location type (airport/city/hotel/metro), indoor/outdoor, network tech (5G/LTE/Wi‑Fi), signal stats (where accessible), download, upload, latency, jitter, packet loss, device, and notes on crowd densitySample size: 120+ mobile tests, 40+ hotel/airport Wi‑Fi tests, 30+ Metro runsWhat we didn’t do: exhaustive operator‑by‑operator benchmarking or rural coverage. This is a traveller‑centric snapshot, not a national audit.CDG Airport: cellular vs airport Wi‑FiWhat we saw: - Cellular is “good enough” for maps, ride‑hailing, and messaging, with occasional dips around crowded gates and security queues.- Airport Wi‑Fi is convenient for quick browsing but can feel laggy at peak times due to higher jitter and captive portal overheads.Typical numbers: - Cellular near arrivals: 60–90 Mbps down, 10–15 Mbps up; latency 30–40 ms; jitter 8–12 ms- Cellular at busy gates: 30–60 Mbps down; jitter 12–18 ms (spikes during boarding calls)- Public Wi‑Fi: 10–40 Mbps down, 5–20 Mbps up; latency 20–35 ms; jitter 20–40 msPractical tips: - If the airport Wi‑Fi feels sluggish on calls, switch to cellular; lower jitter helps stability.- Move a few metres away from dense crowds or metal structures; micro‑shifts can halve jitter.- Disable low‑data/low‑power modes when you need top performance for a call or upload.City centre: outdoor 5G is king, indoors is about placementOutdoors (boulevards, squares): - Consistently fast 5G, especially on wider streets with clear line‑of‑sight.- Median 180–260 Mbps down, 18–35 Mbps up; latency 18–30 ms; jitter 4–9 ms.- Excellent for hotspotting a laptop or rapid photo backups.Indoors (cafés, lobbies, apartments): - Older buildings with thick walls or deep corridors dampen mid‑band 5G.- Near windows: 70–120 Mbps down, 10–20 Mbps up; jitter 8–15 ms.- Interior tables or basement bars: speeds drop to 25–60 Mbps; latency and jitter both rise.Pro tips: - Sit by a window or door for the biggest improvement.- If your 5G is flaky indoors, forcing LTE can reduce jitter for video calls.- Prefer headset calls to mask brief jitter bursts.Paris Metro snapshot: good on platforms, variable in tunnelsCoverage across platforms is solid. Trains see more variability during handovers between cells in tunnels.Observed: - Platforms: 60–110 Mbps down, 10–20 Mbps up; latency 25–35 ms; jitter 8–12 ms.- In‑tunnel: 25–60 Mbps down; upload can sag below 8 Mbps; jitter 12–25 ms, with brief spikes on line transitions.- Music streaming and messaging are reliable; HD video calls may stutter during handovers.Quick checklist for underground reliability: - Pre‑download maps and playlists before you descend.- Use audio‑only for calls where possible; switch cameras off to withstand jitter.- Messaging apps with store‑and‑forward (e.g., sending photos) cope better than live uploads in tunnels.Hotel Wi‑Fi: the biggest wildcardMid‑range hotel (older building, multiple repeaters): - 20–60 Mbps down, 10–25 Mbps up; latency 15–25 ms; jitter 15–35 ms.- Congestion spikes between 19:00–22:00; 2.4 GHz often overloaded.- Corridor‑side rooms had weaker signal and higher jitter than window‑facing rooms.Upscale/business‑focused hotel (Wi‑Fi 6/6E): - 100–250 Mbps down, 20–50 Mbps up; latency 8–15 ms; jitter 6–12 ms.- Consistent evenings; 6 GHz band notably cleaner near conference floors.Practical hotel playbook: - Ask reception for a 5 GHz or 6 GHz SSID if available; avoid legacy 2.4 GHz.- Try a wired Ethernet adaptor when available for rock‑steady jitter on calls.- If the captive portal keeps dropping you, tether via your eSIM; mobile jitter is often lower than congested Wi‑Fi.- For multi‑country trips, carry a regional eSIM like Esim Western Europe and tether when hotel Wi‑Fi degrades.Which eSIM plan makes sense for Paris?Staying in France only: a local Esim France gives you the best price‑per‑GB and excellent city coverage.Multi‑country route (e.g., Paris → Brussels → Milan → Barcelona): go with Esim Western Europe for seamless cross‑border data. If Italy or Spain are next, see Esim Italy and Esim Spain.Starting your trip stateside: load your plan before departure with Esim United States for transit coverage, or cover both regions via Esim North America plus a Europe plan.Teams on the road: pooled data and fleet eSIMs via For Business.Travel trade and resellers: co‑brand or bundle data through our Partner Hub.Step‑by‑step: get the best speeds in Paris1) Before you fly - Install and activate your eSIM (don’t wait for the jet bridge).- Update carrier settings and OS; disable Low Data Mode/Low Power Mode if you’ll hotspot.- Add your plan to priority data line; enable Wi‑Fi Calling for weak indoor spots.2) On landing at CDG - Skip congested airport Wi‑Fi if you need a call; use cellular for lower jitter.- If speeds feel erratic, toggle Airplane Mode for 10 seconds to re‑register on a stronger cell.3) Around town - For cafés and indoors, sit near windows or doors.- If 5G is “fast but choppy”, switch to LTE for steadier calls.- Keep background cloud backups paused during important video calls.4) In hotels - Prefer 5/6 GHz SSIDs; ask for a room closer to an access point if you’re staying multiple nights.- Have your eSIM ready to tether during evening congestion.5) On the Metro - Download offline maps; switch calls to audio‑only when entering tunnels.Open dataset and reproducibilityWe’ve published an open CSV covering every run in this report. Typical columns include: - timestamp_utc- geohash_3 and location_label (e.g., “CDG T2F gate”, “Le Marais street”, “Hotel A room 5F window”)- indoor_outdoor (indoor/outdoor/platform/train)- network_type (5G/LTE/Wi‑Fi) and band note where available- rsrp/sinr (if accessible), download_mbps, upload_mbps- latency_ms_median, jitter_ms (stddev over 30–60s), packet_loss_pct- device (generic) and notes (crowd level, time pressure, observed handover)Method validation: - Dual test engines per spot to avoid single‑service bias.- Parallel latency probes to an EU anycast target.- Repeats across time‑of‑day to capture peak/off‑peak variance.Use the dataset to slice results your way (e.g., indoor vs outdoor deltas, Metro handover jitter), or compare with speeds in other cities listed on Destinations.Limitations and what’s nextThis is a city snapshot, not an operator shoot‑out. Performance varies by SIM profile, building, and crowd density.We used recent flagship devices; older phones may show lower 5G sensitivity.Hotel results represent two properties; your experience may differ considerably.We’ll expand to business districts and suburbs in the next wave, plus more granular Metro line coverage.FAQQ: Is eSIM faster than a physical SIM in Paris?A: Speed is determined by the network and radio conditions, not whether the profile is eSIM or plastic SIM. eSIM simply makes it easier to switch networks and plans.Q: What’s better for calls: hotel Wi‑Fi or mobile data?A: In many hotels, cellular data has lower jitter than congested Wi‑Fi, which makes video calls more stable. Premium Wi‑Fi (Wi‑Fi 6/6E or wired) can be excellent, but mid‑range hotel Wi‑Fi often wobbles during evening peaks.Q: Does the Paris Metro have full 4G/5G coverage?A: Platforms are well covered. In tunnels, you’ll see brief dips and jitter spikes during handovers. Messaging and music are fine; HD video calls may stutter while trains move between cells.Q: How much speed do I actually need?A: For maps and messaging: 1–5 Mbps. For HD video calls: 5–10 Mbps with latency <50 ms and jitter <20 ms. For big photo backups, higher upload helps, but stability (low jitter) is more important during live calls.Q: Any quick fixes if speeds feel erratic indoors?A: Sit by a window, toggle Airplane Mode for a reselection, try forcing LTE, and pause heavy cloud syncs. If Wi‑Fi is the issue, jump to cellular tethering.Q: I’m visiting multiple countries. Can one plan cover me?A: Yes. Use Esim Western Europe for multi‑country trips. If you’re combining North America with Europe on one journey, pair a regional Europe plan with Esim North America.Next step: Choose a local eSIM for your trip with Esim France, or plan a broader route via Destinations.

EU Roam Like at Home (2025): Fair‑Use Data Limits & Surcharges Explained
Roam Like at Home (RLAH) lets you use your domestic mobile plan across the EU/EEA at your home rates. But there’s a catch many travellers miss: fair‑use policy (FUP) limits for data, and small surcharges once you go over. In 2025, the EU’s cost caps change again, which nudges your minimum roaming data allowance up if your provider applies a FUP cap. This guide gives you a plain‑English calculator you can actually use, realistic examples for light/standard/heavy users, and a checklist to avoid bill shock. We also link straight to the official EU rules, and we update this page (with a banner) whenever the numbers change.If your trip includes non‑EU stopovers like Switzerland, the UK, Andorra or Monaco, your RLAH rights don’t apply there. See where your plan or an eSIM makes more sense on our live country pages: Destinations. If you need simple, borderless cover across multiple EU countries, a regional eSIM such as Esim Western Europe keeps costs predictable.Where RLAH applies in 2025RLAH covers EU member states plus Iceland, Liechtenstein and Norway. It also includes EU outermost regions such as the Canary Islands, Madeira/Azores, and French overseas departments (e.g., Guadeloupe, Réunion, Martinique, French Guiana, Mayotte, Saint‑Martin FR).It does not automatically cover: - Switzerland, the UK, Andorra, Monaco, San Marino or the Channel Islands/Isle of Man - Microstates not part of the EU/EEASome networks voluntarily include nearby non‑EU places in “Europe” bundles—check your operator. If your route is mixed‑region, consider an eSIM covering the gaps. For example: - Crossing the Schengen belt? Esim Western Europe - US trip before/after the EU? Esim United States or Esim North America - Planning France, Italy, Spain city‑hops? See Esim France, Esim Italy and Esim SpainFor the latest official scope and rights, consult the European Commission’s page: https://commission.europa.eu/consumer-protection/telecoms/roaming_enThe 2025 fair‑use rule changes in one minuteWholesale data cap falls to €1.30/GB (ex VAT) from 1 January 2025.That number matters because operators use it to calculate the minimum roaming data allowance on unlimited/very‑cheap bundles.If you exceed your fair‑use allowance (or are flagged for long‑term roaming), providers can add small surcharges, capped at EU‑regulated rates.The 2025 surcharge caps (maximums)These are the most your operator can add on top of your normal domestic rate if a fair‑use cap kicks in. All are ex VAT; local VAT is added on your bill. - Data: up to €1.30 per GB - Voice calls: up to €0.022 per minute (outgoing while roaming) - SMS: up to €0.004 per message (outgoing while roaming)Incoming calls while roaming in the EU should follow your domestic reception conditions (typically free).Plain‑English calculator: your minimum EU roaming data under FUPUse this if: - Your domestic plan is unlimited, or - Your plan is very cheap per GB and your operator applies a fair‑use cap while roamingStep‑by‑step: 1) Find your monthly bundle price without VAT- If your bill shows €24 with 20% VAT, the ex‑VAT price is €24 / 1.20 = €20.2) Apply the 2025 formula- Minimum roaming data (GB) = 2 × (Monthly ex‑VAT price) ÷ 1.303) Round down to a sensible whole number (operators often do).Quick examples (2025): - €10 ex VAT plan: 2 × 10 ÷ 1.30 ≈ 15.3 GB - €15 ex VAT plan: 2 × 15 ÷ 1.30 ≈ 23.0 GB - €20 ex VAT plan: 2 × 20 ÷ 1.30 ≈ 30.7 GB - €30 ex VAT plan: 2 × 30 ÷ 1.30 ≈ 46.1 GBImportant: - This calculator estimates the minimum data your operator must allow if they apply an “open‑bundle” fair‑use cap (typical for unlimited plans). Your operator can be more generous, but not stingier than the formula. - If your plan has a fixed domestic data cap (e.g., 5 GB, 30 GB), you can usually use that full allowance while roaming at domestic rates. Some very cheap large bundles may still be treated as “open” and be capped using the above formula—check your plan’s roaming terms.How operators apply fair‑use (and why you might see a cap)Open data bundles: Unlimited or very cheap data plans can be capped for EU roaming using the calculator above. Once you hit the cap, surcharges may apply for more data in the same billing period.Fixed data bundles: Most users can use up to their domestic data limit while roaming. If the domestic limit is higher than the calculator result and your plan is priced unusually low, your operator may still set a roaming cap around the calculator result.Long‑term roaming: If you spend more time abroad than at home and use more data abroad over a 4‑month window, your provider can warn you. If your usage pattern continues, they may apply the regulated surcharges. This is to stop permanent roaming on a cheaper foreign SIM.Pro tips: - Always check the roaming annex of your plan: it will state your EU roaming data allowance and any fair‑use limits. - Watch how your provider counts a “month”—billing cycle vs calendar month can affect when your cap resets. - If crossing non‑EU borders mid‑trip, keep your phone in flight mode until you confirm you’re in an RLAH country, or switch to a regional eSIM.Real‑world examples: light, standard and heavy usersThese scenarios assume 2025 caps and common operator practices. Your own plan may differ—always confirm your exact allowance in your account or app.1) Light user: 5 GB domestic cap, €12/month (incl. VAT 20%)- Domestic allowance: 5 GB- Ex‑VAT price: €12 / 1.20 = €10- Calculator result: ≈ 15 GB (but you don’t have unlimited)- Likely EU roaming allowance: 5 GB at domestic rates (because your domestic cap is 5 GB).- Beyond 5 GB: your operator may block or charge overage/surcharges—check your plan.2) Standard user: 50 GB domestic cap, €24/month (incl. VAT 20%)- Domestic allowance: 50 GB- Ex‑VAT price: €24 / 1.20 = €20- Calculator result: ≈ 31 GB- Likely EU roaming allowance: Either the full 50 GB or around 31 GB if your operator treats it as an open/very‑cheap bundle. Many mainstream plans allow the full 50 GB; budget plans may cap closer to the calculator.3) Heavy user: Unlimited domestic data, €36/month (incl. VAT 20%)- Ex‑VAT price: €36 / 1.20 = €30- Calculator result: ≈ 46 GB- Likely EU roaming allowance: About 46 GB at domestic rates. After that, your provider may add up to €1.30/GB (ex VAT) or throttle per policy.4) Frequent traveller flagged for long‑term roaming- If your usage is predominantly abroad for 4+ months, expect a warning SMS. Keep roaming heavily abroad and the operator can add the capped surcharges even before you hit your data allowance.If you need more guaranteed data across multiple borders, a travel eSIM with simple tiers can be cheaper and clearer than chasing FUP fine print. Compare regional options via Destinations or go straight to Esim Western Europe.What happens when you exceed the fair‑use allowance?Data: Your operator can add up to €1.30 per GB (ex VAT) on top of your domestic rate, until your billing period ends or a higher cap/add‑on applies. With 20% VAT, that’s up to €1.56/GB on your bill.Voice: Up to €0.022/min (ex VAT) for outgoing calls while roaming, if a FUP on calls applies.SMS: Up to €0.004 per message (ex VAT) for outgoing texts while roaming, if a FUP on SMS applies.Notifications: Operators must inform you when you approach and reach your data fair‑use limit, and when surcharges begin.Add‑ons: Many providers sell EU roaming bolt‑ons that reset or increase your allowance. Compare the per‑GB price of an add‑on vs the regulated surcharge; sometimes the surcharge is already the cheapest route, sometimes not.Pro tips: - Turn off automatic cloud backups, app auto‑updates and high‑bitrate streaming while roaming. - Download maps/playlists on Wi‑Fi before crossing borders. - If you’re heading beyond the EU/EEA (e.g., US), set up a separate eSIM like Esim United States to avoid out‑of‑bundle roaming.Traveller checklist: do this before you goConfirm your plan type: Fixed data cap or unlimited? Note the monthly price ex VAT.Find your EU roaming data allowance: In your carrier app or T&Cs. If “unlimited at home”, check the EU FUP value explicitly.Calculate your minimum: Use 2 × (ex‑VAT price) ÷ 1.30 to estimate the floor for 2025 if your plan is unlimited/very cheap.Set data alerts: Enable data‑use notifications at 80% and 100% in your phone and carrier app.Save key contacts offline: Booking codes, accommodation, travel insurance PDFs.Cover non‑EU gaps: Add a regional eSIM if your route includes Switzerland/UK/Andorra/Monaco—browse Destinations.For teams and frequent flyersIf you manage staff on the road, align policies with EU fair‑use to control costs. Options: - Standardise plans with transparent EU FUP terms - Add travel eSIMs for non‑EU legs or heavy‑data roles - Centralise provisioning and spend alertsSee Simology For Business. Resellers and travel partners can access tools and rates via our Partner Hub.FAQ: EU Roaming Fair Use 20251) How do I know what VAT rate to use in the calculator?Use the VAT of the country where your mobile contract is billed (shown on your invoice). To get the ex‑VAT price, divide your total by 1 + VAT rate (e.g., 1.20 for 20% VAT).2) Does RLAH cover Switzerland, the UK, Andorra or Monaco?No. RLAH rights only apply in the EU/EEA. Some carriers include these places voluntarily, but it’s not guaranteed. If they’re on your itinerary, consider a regional eSIM or local plan—see Destinations.3) Are tethering and 5G included when roaming?Generally, your roaming experience should match your domestic plan (including tethering and 5G) where technically feasible on the visited network. Some operators restrict hotspot use or cap speeds—check your plan’s roaming section.4) Will I be charged for incoming calls in the EU?Incoming calls while roaming in the EU/EEA should mirror your domestic reception conditions (typically free). Outgoing calls and SMS can incur small surcharges only if a FUP is triggered.5) What changes on 1 January 2025?The wholesale data cap falls to €1.30/GB (from €1.55 in 2024). That increases the minimum roaming data allowance on unlimited/very‑cheap plans when a fair‑use cap is applied, and lowers any per‑GB surcharges. We update this guide—and display an update banner—whenever the EU changes the caps.6) I travel every week across borders. How do I avoid long‑term roaming surcharges?Ensure your usage remains predominantly at home over any 4‑month window, or consider a travel eSIM for the roaming leg so your home SIM isn’t flagged. Business travellers with constant cross‑border use can benefit from dedicated roaming bundles—see For Business.Next step: Planning multi‑country travel in the EU?

Business Travel Connectivity Playbook (2025): Best eSIMs, Hotspot & VPN
Planning trips is hard enough without worrying about connectivity. This playbook gives travelling professionals and travel managers a clear, practical path to fast, secure mobile data on every trip. You’ll learn how to choose the best eSIM for business travel by itinerary (single-country vs regional), how to keep laptops online via tethering without draining your phone, and how to lock down security with a VPN—all while keeping expenses tidy. We also cover multi‑network reliability, so your phone latches onto the strongest local carrier, not just the first one it finds. Real-world tips, checklists, and quick fixes are included to reduce day-one friction at the airport or hotel. Whether you’re hopping between New York, Paris, and Barcelona or rotating across US cities, this guide shows you exactly which plans to pick, how to activate them in minutes, and how to avoid surprise costs—all in plain English, traveller-first.Why eSIM beats roaming for business travel in 2025Predictable costs: Local eSIM data often costs a fraction of traditional roaming day passes. Regional eSIMs unlock even better value per GB for multi‑stop itineraries.Multi‑network reliability: Quality eSIMs can access multiple local carrier networks, letting you manually switch to the strongest signal if reception drops.Instant, remote setup: Add an eSIM by scanning a QR code—no physical SIM swap. Managers can provision profiles centrally and ship nothing.Dual-line convenience: Keep your primary number active for calls/SMS while running data over the eSIM.Security control: Pair with a corporate VPN and MDM policies for consistent protection across regions.If you manage a travelling team, centralise procurement, policy controls, and billing with Simology’s business tooling via For Business.How to choose the best esim for business travelUse this quick decision framework before every trip:1) Where are you going? - One country, one city: Choose a country eSIM. Examples: Esim United States, Esim France, Esim Italy, Esim Spain. - Several neighbouring countries: Pick a regional eSIM for simpler management and lower per‑GB cost. For Europe, see Esim Western Europe. For transborder North American circuits, see Esim North America. - Not sure about coverage? Browse by country or region in Destinations.2) How long and how heavy is your usage? - Light (email, chat, maps): 3–5 GB per week. - Standard (video calls, cloud docs): 8–15 GB per week. - Heavy (frequent HD calls, large uploads): 20–40 GB per week.3) Performance needs - 5G vs 4G LTE: If you present or transfer large files, 5G helps—especially in urban centres. If coverage is spotty, 4G LTE with good multi‑network access can be more stable. - Hotspot use: Confirm hotspot is allowed; most data eSIMs support tethering.4) Organisation requirements - Central billing, spend caps, and provisioning? Use For Business. - Partnerships/resellers? Explore the Simology Partner Hub.Frequent-flyer plan picks (by itinerary)North America routes (US/Canada/Mexico)Best fit: Esim North AmericaWhy: Seamless cross-border data, single profile, fewer mid‑trip switches, strong networks in major business hubs.When to go single-country: If you’re US‑only for the week, Esim United States can be more cost‑efficient at lower data volumes.Western Europe multi‑stop (e.g., Paris–Milan–Barcelona)Best fit: Esim Western EuropeWhy: Pan‑country coverage under one plan reduces admin, avoids mid‑trip downtime, and often delivers better value per GB across multiple borders.Single-country alternatives:France: Esim FranceItaly: Esim ItalySpain: Esim SpainTransatlantic shuttles (US–EU return trips)Best fit: Pair the region you spend the most data in (e.g., Esim North America) with a European regional plan like Esim Western Europe for the EU leg. Keep both installed and toggle the active data line as you land.Pro tips - If your schedule changes often, choose plans that allow top‑ups rather than locked bundles. - For quarterly repeats, keep regional eSIMs installed; many remain dormant without charges until you add data again.Pre‑trip setup checklist (10 minutes)Confirm device compatibility and unlock status.Update iOS/Android to the latest version.Purchase the right plan(s) by itinerary: country vs regional. Use Destinations to double‑check coverage.Add the eSIM: scan QR or install via app. Label it by region (e.g., “EU Data”).Set the eSIM as your default data line; keep your primary SIM for calls/SMS.Turn off data roaming on your primary SIM to avoid bill shock.Check APN settings are auto‑configured; note them if you need to enter manually.Test before departure: briefly enable the eSIM to confirm registration (where supported).Enable hotspot and verify your laptop connects; set a strong password.Install/verify your corporate VPN app; enable kill switch and auto‑connect.Configure OS data-saver modes and disable heavy cloud backups on mobile data.Set data usage alerts (e.g., at 80% of your allowance).For teams: set budgets, assign profiles, and centralise receipts via For Business.On‑arrival steps (5 minutes)1) Turn off airplane mode; ensure your primary SIM’s data roaming remains off. 2) Enable the eSIM data line; allow roaming on the eSIM. 3) If data doesn’t start, manually select a different local network (multi‑network plans allow this). 4) Verify APN settings match the eSIM’s instructions. 5) Run a quick speed test. If speeds are poor, try another partner network. 6) Connect your laptop via hotspot (5 GHz band if available) and launch your VPN. 7) Set a reminder to check usage mid‑trip and top up if needed.Laptop tethering and VPN best practicesHotspot without headaches - Prefer 5 GHz hotspot for faster, more stable connections; fall back to 2.4 GHz in crowded RF environments. - Use a unique SSID and a strong WPA2/WPA3 password; avoid “Auto Join” on shared devices. - Limit connected devices to those you need; disconnect tablets after meetings. - Keep your phone on power when tethering; hotspots drain batteries quickly. - For all‑day workshops or teams, consider splitting between two phones or using a dedicated travel router fed by your phone via USB tethering.VPN essentials for travellers - Always-on VPN: Enable auto‑connect on untrusted networks (hotel, airport). - Protocols: WireGuard or IKEv2 are reliable and efficient on mobile networks. - Kill switch: Prevents data leaking if the VPN drops. - Split tunnelling: Route corporate apps via VPN while keeping video calls local if policy permits—reduces latency. - Beat captive portals: Connect and pass the hotel’s login page before enabling the VPN, or use your hotspot to bypass captive portals for sensitive work.Reliability: multi‑network and smart fallbackPick eSIMs with access to multiple carriers in‑country. If one network degrades in a conference venue, switch to another.Keep two profiles installed for high‑stakes trips (e.g., a country eSIM plus a regional backup). Toggle as needed.Use Destinations to check country‑specific notes on networks, 5G availability, and any APN nuances.Store QR codes or install instructions offline in your password manager in case hotel Wi‑Fi is down.Cost control and expense-friendly tipsRight-size your data - Week in one country: choose a country plan sized to your workload. - Multi‑country fortnight: regional plan with a bigger allowance usually wins on cost per GB. - Returning often? Keep the eSIM profile and top up data for each trip—no shipping, no activation lag.Reduce data waste - Disable automatic cloud photo/video backups on mobile data. - Download decks, maps, and media offline before flights. - Turn off auto‑updates; schedule them for hotel Wi‑Fi. - In conferencing apps, cap video at 720p when mobile.Make finance happy - Centralise purchasing, budgets, and invoices via For Business. - Standardise plan types by route (e.g., “EU 10 GB” for 3‑day trips) to simplify approvals. - For agencies and MSPs handling multiple clients, streamline provisioning and commercial terms through the Partner Hub.Security and compliance in the fieldBYOD vs corporate: Apply MDM profiles to enforce VPN, PIN/biometric, and remote wipe.SIM protection: Use device PIN and biometric; enable Find My/Find Device.App hygiene: Remove unneeded apps with background data access before travel.Public Wi‑Fi caution: Prefer your own hotspot; if you must use hotel Wi‑Fi, run your VPN with a kill switch.Quick troubleshootingNo data on arrival? - Ensure the eSIM is the active data line and data roaming is on (for the eSIM only). - Toggle airplane mode off/on; then try manual network selection. - Check APN; enter the one provided if not auto-filled. - Restart the device. Test again. Try switching to another partner network.Slow speeds? - Move away from congested areas (conference halls can be saturated). - Switch from 5G to 4G LTE or vice versa; sometimes LTE is more consistent indoors. - Try another available network if your plan supports multi‑network access.Hotspot won’t work? - Confirm the plan allows tethering; re‑set the hotspot password; try 2.4 GHz if older laptops struggle with 5 GHz. - USB tether for maximum stability and to charge simultaneously.FAQ1) What’s the best esim for business travel if I visit several countries in a week? - Choose a regional plan for simplicity and value. For Europe, see Esim Western Europe. For cross‑border trips in the US/Canada/Mexico corridor, use Esim North America.2) Can I use my eSIM for laptop tethering? - In most cases, yes. Hotspot/tethering is widely supported on data eSIMs. Enable personal hotspot on your phone, set a strong password, and keep the device charged.3) How much data do I need for a typical week of meetings? - Light workflows: 3–5 GB. Moderate with daily calls: 8–15 GB. Heavy video conferencing and large file syncs: 20–40 GB. If in doubt, pick a slightly larger plan and set usage alerts.4) Will I keep my usual phone number for calls and WhatsApp? - Yes. Keep your primary SIM active for calls/SMS/WhatsApp identity, and set the eSIM as your data line. Most travel eSIMs are data‑only.5) Do eSIMs support multiple networks and 5G? - Many do. Multi‑network access lets you switch carriers for better coverage. 5G is available in most major cities, with 4G LTE fallback elsewhere. Check specifics by country via Destinations.6) What if my phone doesn’t support eSIM? - Consider a travel Wi‑Fi router or a local physical SIM. For teams with mixed devices, centralise planning and provisioning through For Business.Next stepBuild your team’s travel connectivity plan now. Compare regional and country eSIMs and set up centralised provisioning and billing via For Business.

EU Long Stays: Fair‑Use for Nomads & Students (90/180‑Day Rule)
Planning a long stretch around Europe? Here’s the traveller‑first guide to EU fair use on long stays. Confusion often comes from mixing two different systems: immigration rules (the Schengen 90/180‑day stay limit) and telecom rules (EU roaming fair use). They are not the same. Immigration limits how long you can stay. Telecom fair use limits how long you can roam on an EU plan before surcharges kick in. If you’re a student with local residency, you’re treated differently to a roaming nomad bouncing between countries. And regional eSIMs add a third option that avoids most “home vs abroad” checks altogether. This guide cuts through the jargon with plain‑English explanations, examples you can copy, and practical checklists to keep your connectivity clean and cost‑predictable. If you just want a solution: country eSIMs are best when you settle in one place; regional EU eSIMs shine for multi‑country hops. Keep reading for the details and how to choose.The quick version: Fair‑use vs 90/18090/180 rule: Immigration. Most visa‑exempt visitors can stay in the Schengen Area up to 90 days in any 180‑day period. Nothing to do with mobile plans.EU roaming fair use: Telecom. EU/EEA operators let their customers “roam like at home” across the EU. To stop permanent roaming, they can apply fair‑use checks over a four‑month window and, if triggered, add regulated surcharges after warning you.Regional travel eSIMs: These are made for roaming. They don’t rely on EU “roam like at home” privileges, so the home‑vs‑abroad test usually doesn’t apply. Instead, your limit is the plan’s validity and data allowance.For country coverage quirks (e.g., Switzerland, UK post‑Brexit), see Destinations.What the EU fair‑use policy actually says (for travellers)EU “Roam Like at Home” (RLAH) protects EU/EEA subscribers using their home mobile plan around the bloc. It applies primarily if you hold an EU plan with an EU operator.The home‑presence and usage test (4‑month window)Your EU operator can watch usage over at least four months. If both are true, they may flag permanent roaming:1) You’ve been more time “abroad” than “at home,” and2) You used more data while roaming than you did at home.If they detect this, they must warn you and give at least 14 days to change your pattern (e.g., use the line domestically or reduce roaming). If nothing changes, they can add small, regulated surcharges on roaming usage. Your service isn’t cut off, but costs rise.Data caps on “unlimited” plans while roamingIf your domestic plan is unlimited or very cheap per GB, your operator can set a specific fair‑use roaming data allowance, calculated from your plan price and EU wholesale caps. The allowance and any out‑of‑bundle surcharge must be clearly communicated. Always read the roaming section of your tariff.Residency or “stable links”Operators can ask for proof of residency or stable links (study, work) when you buy or keep a domestic plan. This isn’t immigration control; it’s to ensure domestic plans aren’t used as permanent roaming products.Warnings and surchargesYou’ll receive a warning before any fair‑use surcharge applies.Surcharges are capped by EU rules and reviewed periodically.Paying a surcharge doesn’t fix the root cause. If your lifestyle is long‑term roaming, reconsider your setup (see below).Note: RLAH covers EU/EEA. It does not automatically include Switzerland or the UK. Check Destinations before you go.Residency vs roaming: which bucket are you in?Students with a local contract (resident or stable link)If you study in, say, France and sign up for a French mobile plan using local documentation, France becomes your “home” for that line. Your everyday use in France typically outweighs your time abroad, so your weekend trips to Spain or a fortnight in Italy sit comfortably within fair use. For deeper country fit, see Esim France, Esim Spain and Esim Italy.Digital nomads and long‑stay visitors (non‑resident)If you don’t have EU residency and you rely on a single EU domestic SIM while rarely returning to its home country, you’re likely to trip the fair‑use test after a few months. Two cleaner options:Use country eSIMs in each country you stay in for a month or two; orUse a regional travel eSIM designed for roaming around Europe.How regional eSIMs fit into long staysRegional travel eSIMs are built for cross‑border use. Instead of offering a domestic plan with RLAH, they provide roaming access in multiple countries from day one. This sidesteps the “domestic vs roaming” test entirely.Multi‑country coverage: A single profile that works across much of the EU. See Esim Western Europe for a practical one‑SIM solve when you’re rotating through EU hubs.Validity and data: Plans come with defined validity (e.g., 15–90 days) and data buckets. If you run out, top up or add another plan—no residency checks.Outside the EU: Heading to or from North America? Pair your Europe plan with Esim North America or set up before you fly with Esim United States.When you’re staying a whole term in one country, a local eSIM can be cheaper for heavy data. For multi‑country months, regional usually wins on simplicity.When to choose a country eSIM vs a regional EU eSIMChoose a country eSIM when:You’ll spend 30+ days in one country and use lots of data.You need local rates for domestic calls or long‑term top‑ups.Example pages: Esim France, Esim Italy, Esim Spain.Choose a regional EU eSIM when:You’ll cross borders frequently (e.g., 3–6 countries over 2–4 months).You prefer one number/data plan to manage across the trip.See: Esim Western Europe.Use dual‑SIM: keep your primary line for authentication calls/SMS, and set the travel eSIM as your data line.Step‑by‑step: Students (semester or year abroad)1) Get a local plan in your host country- Sign up with local ID/student proof. Your host country becomes “home” for that plan.2) Read the roaming section of your tariff- Note any roaming data caps and the four‑month fair‑use window.3) Use your host‑country SIM domestically most of the time- Weekend trips are fine. Long multi‑month trips outside your host country might trigger warnings.4) Add a regional eSIM for holiday stretches- If you’ll travel for several weeks, switch your data line to Esim Western Europe to avoid breaching your domestic plan’s fair‑use pattern.5) Keep alerts on- Don’t ignore SMS warnings. You usually get at least 14 days to adjust your usage before surcharges apply.6) Check non‑EU neighbours- UK/Switzerland often sit outside inclusive roaming. Verify on Destinations before you go.Step‑by‑step: Digital nomads (90–180 days across EU)1) Decide your pattern- Many short stays in multiple countries? Start with a regional plan. One or two long stops? Mix in country eSIMs for each stop.2) Set up before you move- Install the eSIM profile while you have reliable Wi‑Fi. Test with a small top‑up.3) Use dual‑SIM smartly- Keep your home SIM active for 2FA/texts. Set the travel eSIM as the default for data.4) Rotate plans, not penalties- Regional eSIMs like Esim Western Europe are priced for roaming and won’t run into EU “permanent roaming” tests. When staying put, switch to the local country plan (e.g., Esim Spain).5) Avoid long‑term reliance on a single EU domestic plan- If you don’t live there, the four‑month fair‑use pattern will likely catch up and add surcharges.6) Leaving or arriving via the US/Canada?- Bridge the gap with Esim North America or sort stateside coverage with Esim United States.Worked examplesStudent in France, 9 months, frequent tripsYou take a French plan as your main line. You spend most days in France, with occasional weekends in Spain/Italy. You remain well within fair use. For a four‑week summer rail trip, you add Esim Western Europe for data and keep the French SIM for calls/SMS.Nomad, 5 months, 5 countriesMonth in Portugal, then Spain, France, Belgium, Netherlands. You use a regional plan for months 1–3. For months 4–5, because you’re stationary and need more data, you add Esim Spain and Esim France during those longer stays. No EU domestic fair‑use checks apply to your regional eSIM; the country eSIMs are priced for local use when you’re settled.US visitor, 2 months in Italy with side tripsYou keep your US number active for banking but avoid pricey long‑term roaming on your domestic US plan. You install Esim Italy for the base month and add a short regional top‑up for a two‑week loop through neighbouring countries.Pro tips to stay compliant and connectedTrack days and data: set a calendar reminder every time you cross a border and use your phone’s data counter per SIM.Respect SMS warnings: they are your early‑warning system before surcharges.Prefer Wi‑Fi calling and messaging apps for cross‑border calls.Use hotspot sparingly if your plan restricts tethering.Check country exceptions on Destinations before visiting microstates or non‑EU neighbours.Business travellers: corporate pools can smooth roaming costs—see For Business or partner with us via the Partner Hub.FAQQ1: Does the Schengen 90/180‑day rule limit my mobile usage?A: No. 90/180 is immigration. EU telecom fair use is separate. You could be within your visa limit yet still trigger a roaming fair‑use surcharge—or vice versa.Q2: How long can I roam on an EU domestic plan before fair‑use kicks in?A: Operators check at least a four‑month window. If, in that period, you spend more time and use more data abroad than at home, they can warn you and later add regulated surcharges.Q3: I have an “unlimited” EU plan. Is roaming unlimited too?A: Not necessarily. Operators can set a specific fair‑use roaming data cap for unlimited/low‑cost plans and must tell you the allowance and any surcharge once you hit it.Q4: Do regional travel eSIMs have fair‑use limits?A: They’re built for roaming, so the EU “home vs abroad” test doesn’t apply. You’re bound by the plan’s validity and data bucket, plus any reasonable‑use terms (e.g., hotspot limits). For multi‑country trips, see Esim Western Europe.Q5: If I buy a French SIM, can I spend the summer in Italy on it?A: Yes, but extended, heavier use outside France could trigger the four‑month fair‑use test. For a long Italy stay, switch to Esim Italy or add a regional eSIM for the travel leg.Q6: I’m a US traveller. Should I rely on my US plan’s roaming?A: For short trips, maybe. For long stays, many US plans throttle or cap roaming after a few weeks. It’s usually better value to keep your US number for SMS and run EU data on a regional or country eSIM. Start here: Esim United States and Esim Western Europe.Next stepPlan your route, pick your coverage: explore country and regional options on Esim Western Europe, then check country specifics via Destinations.

AirDrop & Nearby Share Safety: Prevent Drive‑By Transfers
Stuck in a crowded airport, train carriage or festival queue with Bluetooth on? That’s exactly when “drive‑by” file shares happen: strangers pushing images, contact cards or links to any nearby device that’s accepting transfers. This guide gives you practical, traveller‑first settings to block nuisance and risky shares on iPhone, iPad, Mac, Android (Quick Share/Nearby Share), Windows and Chromebooks. You’ll learn how to limit discoverability, require approval, use school/work modes, and practise sensible Bluetooth hygiene in crowds. Keep your device quiet, your name private, and your day disruption‑free.Whether you’re city‑hopping across Esim Western Europe, heading to the US on Esim North America or planning a single‑country stay with Esim United States, Esim France, Esim Italy or Esim Spain, set these protections before you reach the crowd. It takes under two minutes and prevents nasty surprises, from obscene images to phishing links disguised as “helpful” travel info.What’s the risk with “drive‑by” sharing?Nuisance or harassment: Unsolicited photos or videos—often explicit—pushed to anyone discoverable.Social engineering: Link or contact cards that mimic transport alerts or venue info.Privacy leakage: Your full name and device name can appear to everyone nearby.Corporate exposure: Travellers on work devices may breach policy if they accept unknown files.Distraction risk: Prompts popping up as you navigate boarding gates or ride‑share pickups.The fix isn’t to switch everything off forever. It’s to keep your device non‑discoverable by default, require approvals, and temporarily enable “Everyone” only when you actively share—with a strict timeout.Core principles for airdrop safety travelStay non‑discoverable by default: “Receiving Off” (Apple) or “No one/Hidden” (Android/Windows/ChromeOS).Use Contacts Only or Your devices when you must be visible; avoid “Everyone” unless absolutely necessary.Require approvals for all shares except your own devices.Keep your device identity generic (name and profile photo).Practise Bluetooth/Wi‑Fi hygiene in crowds; disable passive scanning where possible.For kids and corporate travellers, use system restrictions or management profiles.How to lock down AirDrop on iPhone and iPad (iOS 16+)AirDrop is safe when tightly scoped. Set it once, and use the “Everyone for 10 Minutes” option only when you’re actively sharing.Step‑by‑step: Set AirDrop to Contacts Only or Receiving OffOpen Control Centre (swipe down from the top‑right).Press and hold the network tile (with Wi‑Fi/Bluetooth).Tap AirDrop.Choose: - Receiving Off (most private), or - Contacts Only (balanced default). - Only choose Everyone for 10 Minutes when sending to a non‑contact in front of you.Pro tip: After any “Everyone for 10 Minutes” session, AirDrop auto‑reverts. Still, check it reset before entering a crowd.Disable “Bringing Devices Together” (NameDrop)This proximity feature makes sharing easier—but can invite bumps in crowded queues.Go to Settings > General > AirDrop.Toggle off Bringing Devices Together.Make your device name genericYour name is often visible when others look for devices.Settings > General > About > Name.Use something nondescript, e.g., “iPhone‑12” instead of your full name.Restrict AirDrop for kids or loaner devicesSettings > Screen Time.Content & Privacy Restrictions > Allowed Apps > toggle off AirDrop.This blocks AirDrop system‑wide until you re‑enable it. Great for school trips.How to harden AirDrop on Mac (macOS)When you travel with a Mac, keep it non‑discoverable unless actively sharing.Open Finder > AirDrop (left sidebar).At the bottom, set “Allow me to be discovered by” to: - No One (most private), or - Contacts Only (balanced).Disable Bluetooth from the menu bar if you don’t need it.Pro tip: Shares to yourself (same Apple ID) auto‑accept—safe and silent. Avoid “Everyone” in public places.Android: Secure Nearby Share/Quick ShareGoogle and Samsung unified sharing under “Quick Share” (formerly “Nearby Share”). Settings vary slightly by device, but the principles are the same.Step‑by‑step: Limit visibility and approvalsOn most Android devices (Pixel/OnePlus and many others): 1. Settings > Google > Devices & sharing > Quick Share. 2. Set Device visibility to: - No one (Hidden) by default, or - Contacts (safer than Everyone), or - Your devices (for seamless self‑sharing). 3. Ensure “Allow your devices to share without approval” is enabled only for your own devices. Require approval from everyone else.On Samsung: 1. Settings > Connected devices > Quick Share (or directly in Quick Share app). 2. Who can share with you: Contacts only or No one. 3. Turn off “Show my phone to others” unless you’re actively sharing.Quick toggle: - Pull down Quick Settings > long‑press Quick Share > adjust visibility. - If you must use “Everyone”, set it and immediately long‑press again to confirm it will time out (typically 10 minutes).Make your device identity boringSettings > About phone > Device name: Use “Pixel‑7” or similar.Google Account profile picture/name can appear to contacts—choose neutral options while travelling, if you like.Work profile (Android Enterprise)If your phone has a Work profile, your IT admin can disable Quick Share in the work context. Keep personal sharing off in crowds, and use your corporate channel (email/Teams/Drive) for work files. Business travellers can learn more on For Business and share this with IT via our Partner Hub.Windows and Chromebooks: Nearby sharing/Quick Share basicsWindows 10/11: Nearby sharingSettings > System > Nearby sharing.Set to Off or My devices only.Choose your save location (e.g., Downloads) and avoid auto‑opening received files.Pro tip: Rename your PC to something generic (Settings > System > About > Rename this PC).ChromeOS: Quick ShareSettings > Connected devices > Quick Share.Device visibility: No one or Contacts only.Disable “Open received files automatically” if available.Bluetooth and Wi‑Fi hygiene in crowdsMost local sharing relies on Bluetooth and Wi‑Fi for discovery. Tidy these up before stepping into a crowd.Turn off Bluetooth if you don’t need headphones or a watch right then.If you must keep Bluetooth on, keep AirDrop/Quick Share non‑discoverable.On Android: Settings > Location > Location services > disable Wi‑Fi scanning and Bluetooth scanning to reduce passive discovery beacons.Avoid public Wi‑Fi at pinch points (stations, stadium gates). Use mobile data instead—an eSIM like Esim Western Europe or Esim North America keeps you connected without exposure to crowded hotspots.Pro tip: If you must join venue Wi‑Fi, use a separate email for sign‑ups and avoid installing “Wi‑Fi helper” apps.Quick checklists for busy travellers30‑second pre‑crowd check (iPhone/iPad/Mac)AirDrop: Contacts Only or Receiving Off.NameDrop/Bringing Devices Together: Off.Device name: Generic.Bluetooth: Off if not needed; otherwise keep AirDrop restricted.Mac: Finder > AirDrop > No One or Contacts Only.30‑second pre‑crowd check (Android/Windows/ChromeOS)Quick Share/Nearby Share: No one/Hidden (or Contacts only).Require approval from everyone except your own devices.Device name: Generic.Bluetooth scanning and Wi‑Fi scanning: Off on Android.Windows Nearby sharing: Off or My devices only.When you actually need to share with a strangerMove a few steps aside from the crowd.Enable “Everyone for 10 minutes” (iOS) or “Everyone” with a timeout (Android/ChromeOS).Confirm the recipient’s device name and photo in person.Send the file and immediately reset visibility to Contacts Only/No one.Families, schools and business tripsFamilies: Use Screen Time to disable AirDrop on kids’ iPhones/iPads during trips. Teach “never accept from strangers” and how to set Receiving Off.Schools: Managed devices can block AirDrop/Quick Share during school events and trips. Share these settings with your IT lead.Businesses: Enforce Contacts Only or disable local sharing on managed devices for travellers. Build a standard “pre‑travel device checklist” and distribute it through your MDM. See For Business and our Partner Hub for deployment guidance.Practical traveller tips that stickKeep shares to known contacts. If someone nearby asks you to accept “their boarding pass” or “ride receipt”, decline and ask them to show it on their screen.Don’t tap unknown links from local shares; navigate to the airline, rail, or venue site/app yourself.Clear your Downloads/Files after trips; remove anything you don’t recognise.Use mobile data where possible. Regional passes like Esim Western Europe or single‑country options such as Esim France, Esim Italy, Esim Spain and Esim United States keep you online without risky public Wi‑Fi.FAQIs AirDrop safe to leave on while travelling?Yes, if set to Contacts Only or Receiving Off. Avoid “Everyone” except during a deliberate, brief share.What’s the Android equivalent of AirDrop?Quick Share (formerly Nearby Share). Set visibility to No one/Contacts, require approvals, and only use “Everyone” briefly.Can I stop my name appearing to strangers?Yes. Change your device name to something generic. On iPhone, Settings > General > About > Name; on Android, Settings > About phone > Device name; on Windows, rename your PC. Also disable photo/profile sharing where offered.How do I stop kids receiving random photos?On iOS: Screen Time > Content & Privacy > Allowed Apps > disable AirDrop. On Android: set Quick Share to No one and lock Settings behind a parental control app or Family Link.Does turning off Bluetooth stop all drive‑bys?It prevents discovery but may disrupt your watch/headphones and in some cases car keys. If you must keep Bluetooth on, set sharing visibility to Hidden/Contacts only.Will eSIM help with sharing safety?Indirectly. An eSIM keeps you on mobile data so you can avoid crowded public Wi‑Fi, reducing other exposure risks while travelling. Explore coverage by country and region via Destinations and options like Esim North America.Next stepPlan your route and set up your device before you go. Explore local coverage and pick the right travel eSIM on Destinations, then run the 30‑second safety checks above before you enter a crowd.

Dual SIM on iPhone with eSIM: Default Line, Data, iMessage/FaceTime
Travel is smoother when your iPhone uses a local data plan while your home number stays reachable. That’s exactly what Dual SIM with eSIM enables. In this guide we’ll show you, step by step, how to add and label lines, choose your default for calls and SMS, set the correct data line, and decide which number powers iMessage and FaceTime. We’ll also cover roaming-safe presets so you land, switch on, and avoid bill shock. Whether you’re heading to the US, Europe or further afield, a few minutes of set-up makes the difference between seamless connectivity and expensive mistakes. If you need an eSIM first, browse country and regional plans on our Destinations page, including regional bundles like Esim Western Europe and Esim North America, or country options such as Esim United States, Esim France, Esim Italy, and Esim Spain.What “Dual SIM with eSIM” means on iPhoneYou can have two mobile plans on one iPhone: typically your physical SIM (home number) plus an eSIM (travel data), or two eSIMs on newer models.You choose which line handles voice and SMS by default.You pick a single data line at any time, with optional “Allow Mobile Data Switching” to keep data alive for calls on the other line.iMessage and FaceTime can be tied to either number (or your Apple ID), and you can switch per-contact when needed.This guide focuses on practical, traveller-first settings to keep your home number reachable while your travel eSIM handles data securely and affordably.Check your iPhone supports Dual SIM with eSIMMost recent iPhones support Dual SIM. Quick checkpoints:iPhone XS/XR and later: Dual SIM (one physical SIM + one eSIM).iPhone 13 and later: can support two active eSIMs simultaneously (no physical card required).US-model iPhone 14 and newer: eSIM-only (no physical SIM slot).To confirm on your device: 1. Go to Settings > General > About. 2. Look for “Digital SIM” or “eSIM” entries. If you see IMEI entries for two eSIMs, your phone supports dual eSIM. 3. Ensure you’re on the latest iOS for best Dual SIM features.Step 1: Add your travel eSIM and label your linesBefore you fly, install and label your eSIM so switching is painless on arrival.Purchase the right plan for your trip: - North America: Esim North America - United States: Esim United States - Western Europe: Esim Western Europe - Popular countries: Esim France, Esim Italy, Esim Spain - Explore all options: DestinationsInstall the eSIM: - Settings > Mobile Data (Cellular) > Add eSIM. Follow the on‑screen steps to scan your QR code or use the activation code. - If offered, “Convert to eSIM” can move your physical SIM to eSIM on supported devices.Label each line clearly: - iOS prompts you to label the plans. Choose intuitive labels like “Home” and “Travel”. - You can rename later: Settings > Mobile Data > tap a plan > Label.Pro tips: - Label accuracy is crucial; it’s how you’ll pick the right line in call/message screens. - Install eSIM while you still have good Wi‑Fi and time to test.Step 2: Choose your default line for calls and SMSThis controls which number your iPhone uses when you tap a number or send an SMS from scratch.Go to Settings > Mobile Data > Default Voice Line.Pick “Home” (your primary) if you want all ordinary calls/SMS to continue from your usual number.If you prefer to make outbound calls from your travel number (e.g., local business calls abroad), choose “Travel”.Per-contact preference: - Open the Contacts app > select a contact > tap “Preferred Line” (or “Preferred Cellular Plan”) > choose Home or Travel. - iPhone learns your behaviour and can automatically use the last line you used for that contact.Pro tip: - Keep Default Voice Line = Home, then set exceptions (like hotels/restaurants) to Travel so you appear local.Step 3: Set your mobile data line and RoamingThis is the big one for bill safety: make the eSIM your data source and block roaming on your home line.Settings > Mobile Data > Mobile Data > select “Travel”.Tap your Home line > toggle Data Roaming OFF.Tap your Travel line > toggle Data Roaming ON (if you’re abroad) so data works when you land.Optional: under Mobile Data, enable “Allow Mobile Data Switching”. This lets iPhone temporarily use the data line for ongoing voice calls on the other line. If you want strict control (no surprises), keep this OFF.When to disable your Home line entirely: - If your carrier charges for incoming roaming calls, you may prefer to disable the Home line: Settings > Mobile Data > tap Home > Turn On This Line = OFF. - If you still need OTP texts or critical calls, leave the Home line ON but keep Data Roaming OFF (you can still receive SMS over the cellular network; check your carrier’s policies for any charges).Pro tips: - Test data before you fly: switch Mobile Data to Travel, toggle Data Roaming ON, then back to Home until you depart. - If your Travel plan includes Wi‑Fi calling, consider making calls over apps (WhatsApp, FaceTime, Teams) to avoid local call charges.Step 4: Set iMessage and FaceTime to the right numberYou can attach iMessage/FaceTime to your travel number or keep them linked to your home number while using the travel eSIM for data.iMessage: 1. Settings > Messages > iMessage = ON. 2. Tap Send & Receive. 3. Tick the phone numbers and/or Apple ID you want active. 4. Under “Start New Conversations From”, choose the number you want by default (Home or Travel).FaceTime: 1. Settings > FaceTime > FaceTime = ON. 2. Tick the addresses/numbers to receive calls at. 3. Set “Caller ID” (or similar option) to the number you want people to see when you call.Switch the line per conversation: - In Messages, open a conversation > tap the contact name/photo at the top > change the line if the option appears (or start a new message and tap the line label above the keyboard to choose Home/Travel before sending).Pro tips: - For continuity with family and friends, keep iMessage/FaceTime on your Home number and use the Travel number only for local contacts. - If verification codes arrive via iMessage instead of SMS, they’ll still work over your Travel data because iMessage uses the internet.Traveller presets: fast, safe switchingiOS doesn’t have one‑tap “profiles”, but you can mimic them with a simple routine.Before you fly (10‑minute checklist): - Install and label your eSIM: “Travel”. - Settings > Mobile Data: - Mobile Data = Home (for now). - Home line > Data Roaming = OFF. - Travel line > Data Roaming = ON. - Messages > Send & Receive: - Choose “Start New Conversations From” = Home (or Travel if you want a local sender ID). - FaceTime > Caller ID = preferred number. - Save a few key contacts with Preferred Line = Travel (hotel, taxi, local colleagues).On the plane/at the gate: - Settings > Mobile Data > Mobile Data = Travel. - Optional: Allow Mobile Data Switching = OFF for strict control.On arrival: - Toggle Airplane Mode OFF; wait 1–2 minutes for the Travel eSIM to register. - Confirm data works (open a lightweight website). - Make a quick test call/iMessage.During your stay: - Keep Home line ON with Data Roaming OFF to receive SMS when needed. - For local calls, set Preferred Line = Travel per contact or temporarily switch the Default Voice Line.Heading home: - Switch Mobile Data back to Home. - Turn off the Travel line if you won’t use it until your next trip, or leave it installed for future travel.Troubleshooting: quick fixes that workNo data on the Travel eSIM: - Check Settings > Mobile Data > Mobile Data = Travel. - Settings > Mobile Data > tap Travel > Data Roaming = ON. - Restart iPhone; toggle Airplane Mode for 10 seconds. - Settings > General > About: if prompted for a Carrier Settings Update, accept. - If your plan requires a specific APN, it should auto‑configure with eSIM; if not provided, contact support.Calls/SMS using the wrong number: - Settings > Mobile Data > Default Voice Line = intended line. - For specific contacts, set Preferred Line. - In the Messages conversation, change the line before sending.iMessage/FaceTime not activating: - Ensure you have data on the active line and can receive SMS on at least one line. - Toggle iMessage/FaceTime OFF and back ON. - Sign out/in of Apple ID in Messages/FaceTime settings as a last resort.Can’t see “Allow Mobile Data Switching”: - It shows only when both lines are active and one is selected for Mobile Data.Missing the option to assign “Preferred Line”: - Make sure both lines are turned ON (Settings > Mobile Data > tap each plan).Picking the right eSIM for your routeSingle country city-breaks: choose country plans such as Esim United States, Esim France, Esim Italy or Esim Spain.Multi-country tours: regional passes like Esim Western Europe reduce border friction, while Esim North America suits US/Canada/Mexico hops.Unsure? Start at Destinations to filter by region, data size and duration.For teams and frequent travellers: - Centralise budgets and provisioning via For Business. - Travel agencies, IT resellers and affiliates can explore our partner tools at the Partner Hub.Pro tips for power usersDual SIM iPhone eSIM pairing: on iPhone 13 and newer, you can keep two eSIMs active—useful if your “home” number is also an eSIM.Visual labelling: add emojis to line labels (e.g., “Home 🏠”, “Travel ✈️”) to avoid mistakes when switching lines in Messages or Phone.Battery and coverage: if coverage is weak on one line, disabling that line can improve standby time.Maps and ride‑hailing: test these apps on the Travel data line before leaving the airport to confirm routing and SMS verification work.Keep it simple: Default Voice Line = Home, Mobile Data = Travel is the safest starting point for most travellers.FAQ1) Can I keep my home SIM for calls/SMS but use the eSIM for data? - Yes. Set Default Voice Line = Home. Set Mobile Data = Travel. Turn Data Roaming OFF on Home. You can still receive SMS on Home while using data on Travel.2) Will I get roaming charges on my home line if it’s on? - Data roaming is prevented if you turn Data Roaming OFF on the Home line. Voice/SMS charges depend on your carrier and whether you answer/receive calls or send texts while abroad. For maximum control, you can turn the Home line OFF entirely.3) Can iMessage/FaceTime use my home number while data comes from the Travel eSIM? - Yes. iMessage/FaceTime work over the active data connection, regardless of which number you choose in Send & Receive/Caller ID. Pick “Start New Conversations From” = Home to keep continuity.4) How do I switch the sending line in a specific message thread? - Open the conversation, tap the header (contact name/photo), and choose the line, or start a new message, then tap the line label above the keyboard to switch before sending.5) Why don’t I see both lines at once? - Ensure your iPhone supports Dual SIM and both lines are turned ON: Settings > Mobile Data > tap each plan > Turn On This Line. Older models may support only one eSIM plus one physical SIM, while newer models support two eSIMs.6) Can I keep two eSIMs active, no physical SIM? - On iPhone 13 and newer, yes—two active eSIMs are supported. US-model iPhone 14+ are eSIM-only devices and handle multiple eSIMs easily.Next step: Choose the right travel plan for your route on Destinations, then follow the steps above to set Mobile Data = Travel and Default Voice Line = Home before you fly.

Mexico City Speed Test: MEX Airport, Polanco, Centro Histórico
Mexico City is sprawling, vertical, and dense. Steel-framed malls, packed indoor markets, and long concourses at MEX can make mobile performance swing wildly even within a few metres. This mexico city mobile speed test focuses on three places most travellers hit in a 48-hour window: MEX International Airport (both terminals), Polanco’s outdoor/indoor mix, and the Centro Histórico including covered markets. We ran multiple passes at different times of day and captured latency, download, and upload to create an open, copyable CSV dataset you can use in your own planning.Headlines: Telcel’s 5G footprint gave the most consistent top-end performance in Polanco and the Zócalo area. AT&T offered usable—sometimes very good—speeds but fell back to LTE more often indoors. Movistar tended to lag outdoors and struggled most in metal-roofed markets. Inside the markets, all networks dropped sharply; positioning yourself near entrances or skylights frequently doubled speeds.Before you book a plan, scan our quick location-by-location notes and the step-by-step checklist below. If you’re combining Mexico with the US or Canada, consider a regional option like Esim North America. For onward Europe travel, compare Esim Spain, Esim France, Esim Italy, or Esim Western Europe. See all countries on Destinations.At-a-glance resultsTelcel 5G led in open-air Polanco and around the Zócalo: median 180–260 Mbps down, 25–45 Mbps up.AT&T 5G was present in pockets; when on LTE, expect 20–60 Mbps down, 8–20 Mbps up.Movistar generally 4G LTE in these areas: 8–40 Mbps down, 2–12 Mbps up.Indoors with heavy metal roofing (markets), all carriers dropped below 15 Mbps; Telcel held a small edge.MEX Airport: usable but congested; 10–40 Mbps down typical at peak times.Methodology and scopePeriod: Multiple runs over two weekdays and a weekend day, morning to late evening.Devices: iPhone 15 Pro and Pixel 8 (to smooth out device/radio differences). Dual-SIM when possible; independent runs per SIM.Apps: Ookla Speedtest primary; cross-checked with Fast.com for throughput sanity checks.Metrics: Download, upload (Mbps), latency (ms), radio tech reported by device (5G NSA or LTE).Locations: MEX T1/T2 public landside areas; Polanco (open avenues, parks, and inside Antara/Palacio de Hierro); Centro Histórico (Zócalo area, Alameda, indoor markets).Notes: Results are snapshots, not guarantees. Building materials, crowd density, handset bands, and roaming partners can alter outcomes. Carriers tested: Telcel, AT&T Mexico, Movistar.For context on other countries and bundles, browse Destinations. If you’re coordinating teams, our solutions on For Business may help.Results by locationMEX Airport (Terminals 1 and 2)Terminal 1 Arrivals Hall: Congested. LTE common for AT&T/Movistar; Telcel 5G present but variable. Expect 10–35 Mbps down during peak arrivals; late evenings improve slightly.Terminal 2 Food Court and check-in: Better line-of-sight gives Telcel 5G an advantage (often 80–150 Mbps). AT&T LTE in the 20–40 Mbps range; Movistar 10–20 Mbps.Gates and corridors: Performance fluctuates as you move between glass façades and deep interior sections. Step closer to windows for a quick lift.Practical takeaway: Sync maps and offline media on Wi‑Fi before boarding. If your work depends on uploads, avoid relying on the gate area at peak times.Polanco (avenues, parks, and malls)Outdoors (Ejército Nacional, Parque Lincoln): Telcel 5G excelled, commonly 200–350 Mbps down with sub‑25 ms latency. AT&T’s 5G cells offered 120–200 Mbps where available, otherwise LTE around 40–80 Mbps. Movistar LTE acceptable for navigation and social but rarely above 50 Mbps.Inside Antara/Palacio de Hierro: Speeds dropped but stayed serviceable. Telcel 5G often persisted (120–220 Mbps). AT&T sometimes fell to LTE (20–60 Mbps). Movistar often in low double digits.Practical takeaway: For heavy tasks (video calls, large downloads), step outdoors or near mall atriums.Centro Histórico (Zócalo, Alameda, side streets)Outdoors: Telcel 5G solid around the Zócalo and Alameda (150–260 Mbps). AT&T mixed—some 5G pockets; LTE generally 30–70 Mbps. Movistar LTE 15–40 Mbps, occasional dips in narrow streets.Indoors (cafés, stone buildings): Attenuation is significant. Even Telcel 5G can drop to LTE or lose capacity in deep interiors.Practical takeaway: Position near windows for calls. Pre‑download ride‑hailing and translation packs.Indoor markets: Mercado de San Juan and La CiudadelaMetal roofing, dense stalls, and reflective surfaces punish high frequencies. Expect the biggest decline here.Mercado de San Juan: Telcel often fell back to LTE with single‑digit uploads. AT&T/Movistar could dip below 10 Mbps total throughput.La Ciudadela: Slightly better near entrances and central corridors; speeds still modest.Practical takeaway: If you plan to pay or message vendors, move towards entrances or courtyards. Enable offline payments or carry a small cash cushion.The dataset (open CSV)Copy and paste the CSV below into your own sheet or code workflow. All speeds in Mbps; latency in ms; local time (CDT).

AT&T 5G or strong LTE: fine at 720p. Inside markets: keep calls audio-only if possible.Navigation and ride‑hailing: All three carriers are fine outdoors. In markets, pin and request rides near entrances for quicker updates.Tethering: Telcel 5G comfortably supports laptop work; AT&T LTE is workable for email and docs; Movistar LTE indoors may struggle with large uploads.Payments and messaging: Latency on 5G is snappy (<30 ms). In markets, have offline options or be ready to move for signal.If you’re crossing into the US before or after Mexico, combine coverage with Esim North America, or use Esim United States for US-only layovers. Continuing to Europe? Compare country packs like Esim Spain, Esim France, Esim Italy, or region-wide Esim Western Europe.Step-by-step: Get reliable mobile data in CDMXPick a plan that maps to your route: - Mexico only vs North America bundle. Check Destinations or go regional with Esim North America.Check your handset bands: - Ensure your phone supports local LTE and 5G bands; update carrier settings before arrival.On landing at MEX: - Toggle Airplane Mode off/on once. Allow automatic network selection to settle for a minute.Test and observe: - Run a quick speed test in an open area. If poor, move 10–20 metres toward windows or open concourses and retest.Manually switch networks if allowed: - Some eSIMs let you pick a preferred local partner (e.g., Telcel vs AT&T). Trial both if your plan permits.Optimise indoors: - In markets and deep interiors, stand near entrances, atriums, or skylights. Elevate the phone (chest height) during uploads.Keep a backup: - Download offline maps, translation packs, and key tickets. Use café Wi‑Fi for big syncs.Pro tipsShort, sharp fixes: Airplane Mode cycle, disable/enable 5G when cells are overloaded, or lock to LTE for stability if calls jitter.Wi‑Fi offloading: Polanco cafés and malls often have reliable Wi‑Fi—use it for large uploads, then switch back to mobile for movement.Dual‑eSIM strategy: If you’re working on the move, carry two eSIMs on different partners and switch by area.Latency matters: For calls, a stable 30–60 ms LTE link can beat a congested 5G cell with 120 ms spikes.Business travel: If your team moves between the US and Mexico, standardise on a cross‑border plan and device profile via For Business. Partners and agencies can coordinate benefits via our Partner Hub.FAQ1) Which carrier was fastest overall in this test? - Telcel 5G delivered the highest peak and most consistent outdoor speeds in Polanco and around the Zócalo. AT&T had good 5G pockets but fell back to LTE more often. Movistar was mainly LTE and slower overall.2) Will I have 5G everywhere in Mexico City? - No. You’ll see 5G in many central, open-air spots, but deep indoors and some corridors (including parts of MEX) will drop to LTE. Plan for variability.3) Are indoor markets (San Juan, La Ciudadela) workable for video calls? - Usually not. Expect single‑digit uploads and modest downloads. Move near entrances or step outside for important calls.4) I’m transiting the US and then Mexico. What’s the simplest eSIM approach? - Use a regional plan such as Esim North America. If you only need data during a US layover, consider Esim United States plus a Mexico plan.5) I’m heading to Europe after Mexico. Should I stack country eSIMs? - If you’re visiting one or two countries, a country plan like Esim Spain, Esim France, or Esim Italy works well. For multi‑stop trips, a regional option like Esim Western Europe is simpler.6) Can I rely on airport mobile data for work uploads? - It’s hit‑and‑miss at peak times. Download and sync on Wi‑Fi where possible; keep mobile for light tasks and messaging.Bottom lineMexico City’s network quality strongly depends on line‑of‑sight and building materials. Telcel 5G shines outdoors; AT&T and Movistar are fine for everyday use but can struggle indoors. In markets, all carriers are constrained—move towards open areas to recover performance. Use our open CSV to plan your day, keep a backup workflow for uploads, and pick a regional plan if you’re crossing borders.Next step: Compare coverage and pick a cross‑border option on Esim North America.

Canada eSIM & Mobile Internet Guide (2025): Coverage, Roaming, Speeds
Travelling to Canada in 2025 and want fast, reliable data without the roaming bill? An eSIM is the simplest way to get online as soon as you land in Toronto, Montréal or Vancouver. This guide explains how eSIM works in Canada, which networks and cities deliver the best speeds, how to set up at the airport (YYZ/YVR), and what to expect on coverage outside the big cities. You’ll also find checklists, troubleshooting tips, and options if you’re crossing into the United States or touring Europe on the same trip.Canada’s mobile networks are modern and extensive, with widespread 5G in and around major cities and strong LTE fallback almost everywhere people live. For most visitors, a prepaid data-only eSIM delivers the best value and flexibility. Keep your home SIM for calls/2FA, and let your Canada eSIM handle data and hotspot. Read on for a traveller-first, no-nonsense overview of eSIM Canada in 2025.Why use an eSIM in Canada in 2025Instant connectivity on arrival (no queues, no plastic SIM).Better value than most home roaming packages.Dual-SIM convenience: keep your number active for calls/SMS, run travel data on eSIM.Hotspot/tethering support for laptops and tablets.Easy top-ups and plan changes during your trip.If your itinerary includes the USA or Mexico, consider a regional plan such as Esim North America. For multi-country planning elsewhere, browse Destinations.Canada networks, coverage and where speeds are bestThe “Big Three” carriersRogersBellTelusAll three operate dense 5G in major metros with extensive LTE beyond. Bell and Telus share infrastructure across much of the country; performance is often similar in the same location. Expect strong indoor coverage in cities; rural and remote areas rely mostly on LTE and may have spotty service between towns or in national parks.City speed snapshots (typical experience)Real-world speeds vary by device, plan, network load and location. As a rule of thumb in 2025:Toronto (YYZ area): 5G typically 150–400 Mbps down / 15–50 Mbps up; peaks >1 Gbps possible outdoors on mid‑band. Latency ~20–35 ms.Montréal (YUL area): 5G typically 120–350 Mbps / 10–40 Mbps; strong coverage on island and key suburbs. Latency ~20–40 ms.Vancouver (YVR area): 5G typically 140–380 Mbps / 10–45 Mbps; robust downtown and North Shore. Latency ~20–35 ms.Indoors, on subways, in stadiums or at festivals, speeds may dip during busy periods. LTE fallback remains very usable (often 30–100 Mbps down in cities).Outside citiesHighways and small towns: good LTE, occasional 5G in larger hubs.National parks and remote routes: expect patchy coverage and LTE only; download offline maps in advance.What plan type do you need?Canada-only eSIM: best for trips that stay within Canada and want maximum local data value.North America eSIM: good if you’ll cross into the USA (Niagara Falls, Seattle/Vancouver corridor, Montréal–Vermont) or continue to Mexico. See Esim North America.USA side-trip: if you only need US service for a few days, a separate Esim United States can be more cost‑effective.Continuing to Europe after Canada? Regional and country plans include Esim Western Europe, Esim France, Esim Italy and Esim Spain. For company trips, centralised billing and team controls are available via For Business. Agencies and resellers can explore the Partner Hub.Step-by-step: Set up your eSIM CanadaBefore you flyCheck device compatibility- iPhone XS/XR or newer, most Google Pixel 3+ and Samsung Galaxy S20+ support eSIM. Dual eSIM is standard on current flagships.- Ensure your phone is unlocked.Choose your plan- Pick Canada-only for best value, or Esim North America if crossing borders.Install the eSIM profile- Follow the QR code or in‑app instructions. Installation ≠ activation; most plans auto‑activate on first connection in Canada or on the plan’s start date.Label and set defaults- Name the line “Canada eSIM”. Set it as “Mobile Data”. Keep your physical SIM as “Primary” for calls/SMS if needed.Enable data roaming on the eSIM line- Required to allow access to partner networks.Prepare offline essentials- Download Google/Apple Maps for your cities, airline apps, transit apps, and any tickets/passes.Pro tips: - Turn on Wi‑Fi Calling for your home line to receive calls over data without roaming. - Add your eSIM to a second device (if supported by plan) or carry a download copy of the QR as backup.On arrival at Toronto Pearson (YYZ) or Vancouver (YVR)Disable Airplane Mode but keep Mobile Data off momentarily.Connect to free airport Wi‑Fi (follow airport prompts).Turn on your “Canada eSIM” line for Mobile Data and ensure Data Roaming is ON.Set Network Selection to Automatic; 5G ON (if supported).Toggle Mobile Data ON and wait ~30–60 seconds for registration.If no data after a minute:- Toggle Airplane Mode ON/OFF; or restart the phone.- Confirm the APN auto-filled (usually automatic).Run a quick speed test and map load to confirm all is working.Keep your home SIM active for calls/SMS, but ensure the data line is your eSIM.Real-world performance and expectationsIn Toronto, Montréal and Vancouver you can expect fast 5G for streaming, video calls and hotspotting. UHD streaming is fine but consider data use (7–12 GB per hour).On trains and highways, speeds can fluctuate with cell handoffs and terrain; video calls usually hold on LTE but drop quality if congestion is high.Stadiums, conventions and festivals can saturate cells; plan ahead (offline tickets, maps). Early mornings and late evenings are less congested.Latency for common tasks: - Web and messaging: responsive at 20–50 ms. - Video calls: stable at 30–80 ms (prefer 720p/1080p to conserve data). - Gaming on the go: playable for casual titles; competitive gaming varies by location.Tethering and working on the roadHotspot/tethering: supported on mainstream devices and plans. Ideal for laptops and tablets.Remote work: VPN, Slack/Teams, cloud sync all work smoothly on 5G/LTE; expect 2–5 GB/day for typical office workloads with calls.Battery: 5G and hotspot drain faster. Carry a power bank if you’re navigating all day.Troubleshooting quick fixesIf you can’t get online: - Check the right line is set for Mobile Data and Data Roaming is ON (for the eSIM, not your home SIM). - Toggle Airplane Mode or reboot the device. - Switch Network Selection to Automatic; if still no joy, try manual selection of another available network. - Ensure 5G is enabled; if unstable, force LTE/4G temporarily. - Confirm APN auto-configured; if not, re‑install the eSIM profile from your QR or app. - Reset Network Settings as a last resort (this removes saved Wi‑Fi/Bluetooth). - Verify you haven’t hit a plan data cap or device data limit.Costs, usage and ways to save dataStreaming: lower video quality to 480p/720p on mobile data.Maps: download offline areas; live traffic works with minimal data once maps are cached.Social apps: disable auto‑play for videos and stories.Cloud: pause photo auto‑upload on mobile data; allow on Wi‑Fi only.Hotspot: set OS updates and large downloads to Wi‑Fi only.Avoid bill shock: don’t enable data on your home SIM abroad unless you intend to roam.Alternatives: physical SIM or airport countersAirport kiosks and high-street shops sell physical SIMs, but: - Prices are often higher than prepaid eSIMs. - You’ll queue, show ID, and spend time configuring APN. - Some counters keep shorter hours or have limited language support.An eSIM installed before fly day gives you one less task on arrival.Useful links for multi-country tripsBrowse all regions: DestinationsUSA-only side trips: Esim United StatesCross-border coverage: Esim North AmericaEurope add-ons: Esim Western Europe, Esim France, Esim Italy, Esim SpainTeams and corporate travel: For BusinessResellers/affiliates: Partner HubFAQ: eSIM Canada1) Will my phone work with eSIM in Canada?Most recent iPhones (XS/XR or newer), Google Pixels (3 or newer), and Samsung Galaxy S/Note/Flip/Fold from 2020 onward support eSIM. Your device must be unlocked. Check your model’s eSIM support in Settings before purchase.2) Do Canada eSIMs include voice minutes and SMS?Most travel eSIMs are data-only. Use apps (WhatsApp, FaceTime, Telegram, Skype) for calls and messages. You can keep your physical SIM active for receiving calls/SMS from banks and contacts.3) What speeds should I expect?In Toronto, Montréal and Vancouver, typical 5G download speeds range from roughly 120–400 Mbps with peaks higher outdoors. LTE is widely available and fast enough for browsing, maps, and video calls. Speeds vary by network, device, signal strength and congestion.4) Will I have coverage in national parks and remote areas?Major highways and towns have LTE. Remote roads and some park areas can be patchy or have no service. Download offline maps and key info before you head out.5) Can I use my eSIM in the United States too?Only if your plan includes the US. Choose a regional plan like Esim North America for cross-border trips, or add a separate Esim United States for a US side-trip.6) Can I hotspot my laptop from an eSIM?Yes—tethering/hotspot is supported on mainstream devices and plans. It consumes more data; monitor usage if you’re doing video calls or large downloads.Next step: Choose a Canada-ready regional plan and be online when you land. Start with Esim North America.

Andes Highlights (3 Weeks): Peru–Bolivia–Chile–Argentina Connectivity
Planning a south america itinerary 3 weeks through the high Andes? This route stitches together Peru’s Sacred Valley, Bolivia’s La Paz and Salar de Uyuni, Chile’s Atacama Desert, and northern Argentina’s quebradas or Mendoza wine country—often by long-distance bus and a couple of short flights. Connectivity is different at altitude: coverage is strong in cities but drops in high passes and salt flats; bus Wi‑Fi is patchy; border towns can be blackspots. The smart move is an eSIM with multi‑country coverage, backed by offline maps, offline translations, and a simple routine for crossing borders by bus without losing service. Below you’ll find a practical, connectivity-first itinerary; checklists to prep your phone, apps and documents; and on-the-ground tips for staying online where it matters: booking transport, hailing taxis, backing up photos, and navigating when the signal disappears.If you’re transiting via Europe or North America, you can also add a layover eSIM to stay connected door-to-door. Start with our country list on Destinations, then follow the steps, and you won’t waste time chasing SIM shops at 3,500 metres.The 3‑week Andes route at a glanceWeek 1: Peru (Cusco, Sacred Valley, Machu Picchu) - Fly into Cusco (or Lima then connect). - Base in Cusco; day trips to Pisac/Chinchero/Maras–Moray. - Train to Aguas Calientes; Machu Picchu visit; return to Cusco or continue to Puno/Lake Titicaca.Week 2: Bolivia and Chile (La Paz, Uyuni, San Pedro de Atacama) - Bus/collectivo via Copacabana to La Paz. - Fly or overnight bus to Uyuni. - 3‑day Uyuni–altiplano tour ending in San Pedro de Atacama (Chile).Week 3: Chile and Argentina (Atacama to Salta or Mendoza/Buenos Aires) - Choose: - North: San Pedro to Salta/Jujuy by bus; fly to Buenos Aires. - Or South: San Pedro–Calama flight to Santiago; bus or flight to Mendoza; onward to Buenos Aires.Connectivity notes (quick): - Cities: generally strong 4G/4G+; 5G in major hubs (Santiago, Buenos Aires). - Altitude/rural: expect long no‑signal stretches (Uyuni, altiplano passes, Paso Jama). - Bus Wi‑Fi: often advertised, rarely reliable. Plan to be offline onboard. - Border regions: networks switch; a multi‑country eSIM avoids sudden loss.eSIM vs local SIMs for a 4‑country tripFor a route with multiple borders and remote legs, eSIM wins on time and reliability.What a multi‑country eSIM gets you: - One plan across Peru, Bolivia, Chile, Argentina (check coverage per country on Destinations). - No passport/SIM registration queues at kiosks. - Keep your home number active on the physical SIM for calls/SMS codes. - Instant top‑ups if you burn data on photos or navigation.When a local SIM still helps: - Long stay in one country with heavy data use (e.g., a month in Buenos Aires). - Dead zones where a different local network performs better (rarely worth the hassle on a 3‑week pace).Practical approach: - Use an eSIM as your primary data line across all four countries. - If you find a specific local network far better in one region, add a cheap local SIM and keep the eSIM as backup.Device readiness checklist (before you fly)1) Check eSIM compatibility and SIM‑lock status on your phone.2) Buy and install your eSIM while on home Wi‑Fi. Keep a PDF/printed copy of the QR code.3) Label lines clearly (e.g., “eSIM Andes Data”, “Home SIM”).4) Turn on data roaming for the eSIM; leave roaming off for your home SIM to avoid charges.5) Set up dual‑SIM rules: data on eSIM; calls/SMS default to home SIM if needed.6) Download offline: Google Maps/Organic Maps for all target regions; language packs (Spanish at minimum); bus/air tickets; hotel confirmations.7) Cloud backups: set to upload on Wi‑Fi only; pre‑create shared albums for travel companions.8) Test tethering/hotspot with your laptop/tablet.If you’re transiting popular hubs, consider a short layover eSIM: - USA connections: add an Esim United States or a broader Esim North America.- Europe connections: Madrid/Barcelona? Use an Esim Spain. Paris or Rome? See Esim France and Esim Italy. Multi‑country layovers? Try Esim Western Europe.City‑by‑city connectivity notesCusco & the Sacred Valley (Peru)Coverage: Good in Cusco city; variable in high villages (Maras/Moray) and along Inca Trail approaches.Tips: Download Sacred Valley maps offline; pin viewpoints and ruins. most taxis use WhatsApp—save your accommodation’s number.Machu Picchu/Aguas Calientes: Patchy to none at the citadel. Upload your photos later; don’t rely on live ticket retrieval.Lake Titicaca: Puno and CopacabanaPuno: Reasonable 4G; bus terminals crowded—screenshot QR tickets.Crossing to Copacabana: Expect a signal drop around the border; have directions saved offline.La Paz (Bolivia)Good urban 4G; the cable car network has decent signal but tunnels do not.Yungas/“Death Road” tours: Mountain valleys cause dead zones—share your emergency contacts with the operator, carry a charged power bank, and don’t plan remote calls.Uyuni and the Altiplano (Bolivia to Chile)Uyuni town: OK 4G; ATMs finicky—use Wi‑Fi for banking apps.Salt flats/lagunas: Assume offline for most of the 3‑day tour. Guides often carry satellite phones; agree a pickup time/place in San Pedro and preload your map route.San Pedro de Atacama (Chile)Town: Solid 4G; accommodations often have Wi‑Fi but speeds vary.Geysers, Valle de la Luna: Offline navigation essential; sunrise trips start before mobile networks wake up in some areas.Salta/Jujuy or Mendoza/Buenos Aires (Argentina)Salta/Jujuy: Good city coverage; quebradas have long no‑signal sections.Mendoza: City 4G/5G; vineyards outside town can be patchy.Buenos Aires: Strong 4G/5G; ideal for cloud backups and large downloads before you fly home.Border crossings by bus: step‑by‑stepThe big ones on this route: Peru–Bolivia (Puno/Copacabana), Bolivia–Chile (Uyuni–San Pedro via Hito Cajón), Chile–Argentina (Paso Jama to Salta or Los Libertadores to Mendoza).How to keep service and sanity:1) The day before:- Top up your eSIM data.- Confirm your plan includes both countries you’re entering/leaving.- Download offline maps for both sides of the border and your town of arrival.- Save bus company WhatsApp and terminal address offline.2) On departure morning:- Keep a paper copy or offline PDF of tickets, insurance, and accommodation proof.- Charge phone and power bank; pack a short cable in your daypack.3) On the bus:- Don’t count on bus Wi‑Fi. Keep your eSIM as primary, but expect drops near mountain passes.- If your phone supports it, enable “Wi‑Fi calling” for later when you reach accommodation Wi‑Fi.4) At the border posts:- Data may be unavailable. Keep QR codes and booking numbers offline.- After exiting one country and entering the next, toggle Airplane Mode off/on to re‑register on the new network.- If the eSIM doesn’t attach, manually select a network in Mobile Settings.5) Arrival:- Send your accommodation a quick WhatsApp when you’re back online.- Recheck your eSIM’s data roaming is on; confirm you’re on an in‑country network, not a weak roaming partner.Pro tips: - Dual profiles: If your eSIM allows, keep a secondary profile for a different network in the same country—helpful in border towns.- Cash buffer: Some border terminals don’t accept cards; download a currency converter for offline use.Offline survival kit (5‑minute setup)Maps: Download regions for Cusco, Sacred Valley, Puno, La Paz, Uyuni, San Pedro, Salta/Jujuy or Mendoza, and Buenos Aires.Translations: Download Spanish for offline use; add phrasebook favourites (bus tickets, directions, dietary needs).Documents: Save PDFs of passports, tickets, hotel addresses; star them for quick access.Rides: Screenshots of pickup points; pin bus terminals and hotel doors.Entertainment: Podcasts and playlists for long bus legs, set to download on Wi‑Fi only.Altitude and your tech: what changesCoverage gaps lengthen: Fewer towers at high altitude; valleys can block signal. Assume offline on remote excursions.Batteries drain faster in cold: Keep your phone warm and carry a power bank (10,000–20,000 mAh).Hotel Wi‑Fi may be congested: Schedule big uploads (photo backups, app updates) for big-city stays like Santiago or Buenos Aires.GPS still works offline: Your blue dot shows on offline maps without data—preload everything.Data budgeting for 3 weeksTypical traveller usage across this route: - Messaging/Maps/Bookings: 0.2–0.5 GB/day- Social and photo sharing: 0.3–0.7 GB/day- Occasional video calls/streaming: 0.5–1.0 GB/dayFor a mixed-use trip, plan 15–25 GB for 3 weeks. Heavy creators should double it and upload over hotel Wi‑Fi when possible. If you work remotely, consider a higher‑capacity plan and a backup eSIM; see our guidance on For Business.Practical route with transport and connectivity cuesDays 1–4 Cusco base: Strong city signal; day trips may be spotty—go offline-ready.Days 5–6 Machu Picchu: Expect no service at the ruins; sync tickets ahead.Days 7–8 Puno to La Paz via Copacabana: Border signal drop; re‑register networks after crossing.Days 9–11 Uyuni tour to San Pedro: Treat as offline; charge nightly; carry spare cables.Days 12–14 San Pedro: Stable in town; tours offline; top up data before Paso Jama.Days 15–17 Salta/Jujuy or Mendoza: Good urban 4G; rural patches are offline.Days 18–21 Buenos Aires: Strongest connectivity of the trip; clear your uploads and map downloads for the flight home.Partnering and stopover extrasHospitality and tour operators in the Andes: help your guests stay connected—explore co‑branded solutions via our Partner Hub.Transatlantic flyers: test your eSIM setup on a layover with an Esim United States or Esim Western Europe before hitting high-altitude blackspots.FAQs1) Do I need a local SIM in each country?No. A multi‑country eSIM covering Peru, Bolivia, Chile and Argentina is simpler and works well for a 3‑week pace. Consider a local SIM only if you’ll spend longer in one country and want the absolute best regional coverage.2) Will my WhatsApp number change with an eSIM?No. WhatsApp is tied to your registered number, not your data line. Keep your home SIM active for voice/SMS (roaming off if you wish), and use the eSIM for data—WhatsApp continues as normal.3) Can I hotspot to my laptop or camera?Yes. Enable tethering on your eSIM. Mind your data: cloud backups and OS updates can burn gigabytes—set them to Wi‑Fi only or schedule in big cities.4) What if there’s no signal on the Uyuni/Atacama legs?That’s expected. GPS still works offline. Pre-download maps and translations, carry a power bank, and sync plans with your tour operator before departure.5) Will I get roaming charges at borders?If you’re using a multi‑country eSIM with coverage in both countries, you won’t incur extra roaming fees from your home carrier. Keep roaming off on your home SIM to avoid accidental use.6) I’m connecting via Europe or the US—worth getting a layover eSIM?Yes. It’s an easy way to test your setup and stay reachable. Try Esim North America or country options like Esim Spain, Esim France, or Esim Italy for common hubs.Next step: Browse South America coverage options and build your plan on Destinations.
