Before you start: what you need

Estimated time: 5–10 minutes
Cost: Free to install (plan cost varies)

An iPhone 15 or iPhone 16 running current iOS (Settings > General > Software Update).
Reliable Wi‑Fi (strongly recommended during activation).
Your eSIM details:
Either a QR code, or
Manual activation details: SM‑DP+ address, Activation Code, and (if provided) Confirmation Code.
If transferring from another iPhone: both phones on iOS 16+ and signed into iCloud with Bluetooth on.

Quick checks: - Remove any old VPN profiles (Settings > General > VPN & Device Management) if they may interfere. - Backup screenshots or a PDF of your QR code so you have it offline on arrival.

Compatibility note: - iPhone 15/16 models sold in the United States are eSIM‑only. International variants generally still include a physical SIM tray. All support multiple eSIMs with up to two lines active at the same time.

Step-by-step iPhone eSIM setup

You can add an eSIM in four ways. Use the method your provider supports.

Tip: If your provider instructs you to activate only after you land, you can still pre‑install the eSIM over Wi‑Fi and toggle it on later.

Option 1: Install via QR code (fastest)

Connect to Wi‑Fi.
On your iPhone: Settings > Mobile Data (Cellular) > Add eSIM.
Tap Use QR Code and point the camera at your code.
When prompted, tap Continue. If asked, choose to Add eSIM.
Wait for “Activating” to complete. This can take 1–3 minutes.
Label the line (e.g., “Japan data”).
Set as your Mobile Data line if it’s your travel plan. Keep your home line for calls/SMS if needed.
Leave Data Roaming off until you arrive, unless your plan requires activation at purchase.

If you see “Invalid QR Code” or “Plan Cannot Be Added”, see Troubleshooting.

Option 2: Enter details manually (SM‑DP+ and Activation Code)

Settings > Mobile Data > Add eSIM > Use QR Code > Enter Details Manually.
Enter: - SM‑DP+ Address: e.g., “xyz.smdp.com” (exactly as provided) - Activation Code: long string (case‑sensitive) - Confirmation Code: only if your provider lists one
Tap Next and wait for activation.
Label and assign the line for data as needed.

Tip: Typo‑sensitive. Copy/paste carefully. Double‑check dots and dashes.

Option 3: Install via carrier/app

Install your provider’s app from the App Store.
Create/log in to your account and purchase/assign the eSIM to your device.
In the app, select “Install eSIM” and follow the prompts.
When iOS prompts to add the plan, confirm and wait for activation.

Option 4: eSIM Quick Transfer (moving from your old iPhone)

Put both iPhones side by side with Bluetooth on and signed into iCloud.
On your new iPhone: Settings > Mobile Data > Add eSIM > Transfer From Nearby iPhone.
On your old iPhone, approve the transfer and choose the line.
Wait for activation on the new device and confirm the line is working.
Decide whether to keep the eSIM active on the old phone (usually off for travel).

After activation: configure for travel

These post‑install settings make the difference between “it works” and “it works every time”.

Label lines: Settings > Mobile Data > tap the new plan > Label.
Default line:
Mobile Data: choose your travel eSIM.
Voice: choose your home line if you want your usual number active.
iMessage & FaceTime: Settings > Messages/FaceTime > Send & Receive > pick the appropriate number/email.
Data Roaming: Toggle on when you land in your destination.
Network Selection: If auto fails, try manual. Settings > Mobile Data > Network Selection > turn off Automatic and choose a listed partner network.
5G/LTE: Settings > Mobile Data > Mobile Data Options > Voice & Data > try 5G Auto/On or LTE per provider guidance.
Low Data Mode: Turn off if speeds seem throttled unnecessarily.

APN and data settings (only if needed)

Most eSIMs auto‑configure APN. If data connects but webpages won’t load, set APN manually.

Go to Settings > Mobile Data > your eSIM plan > Mobile Data Network (Cellular Data Network).
Under Mobile Data (Cellular Data):
APN: enter the exact APN value provided (e.g., “internet”, “fast.t-mobile.com” — this will vary).
Username/Password: leave blank unless specified.
MMS/Personal Hotspot APNs: set only if you’ve been given values.
Return one level and reboot the iPhone if the change doesn’t apply immediately.

Pro tips: - If the APN field is missing or greyed out, your profile is locked by the carrier; contact support to push correct settings. - “Could not activate mobile data network” usually means incorrect APN or temporary network registration delay. Recheck APN and toggle Airplane Mode for 20 seconds.

Troubleshooting: top errors and fast fixes

If activation fails, work methodically. Most issues resolve in under 5 minutes.

1) “Invalid QR code” / “This code is no longer valid” - Cause: Code already redeemed, expired, or scanned incorrectly. - Fix: - Confirm you’re scanning the most recent QR from your provider. - Try Enter Details Manually (SM‑DP+, Activation Code). - Ask the provider to reissue the eSIM.

2) “Activation unsuccessful” / Stuck on “Activating” - Cause: Wi‑Fi glitch or temporary carrier server timeout. - Fix: - Force‑quit Settings, toggle Airplane Mode on for 20 seconds, then off. - Reboot iPhone. - Switch to a different Wi‑Fi or use a known‑good hotspot. - Try again after 10–15 minutes.

3) “No Service” after install - Cause: Roaming off, wrong network selected, unsupported band, or not yet in the coverage area. - Fix: - Toggle Data Roaming on (when in destination). - Settings > Mobile Data > Network Selection: try manual selection of a partner network. - Settings > Mobile Data Options > Voice & Data: switch between 5G Auto, 5G On, and LTE. - Restart the iPhone.

4) Data doesn’t work; calls/SMS do (or vice‑versa) - Cause: APN not set, wrong default data line, or plan is data‑only. - Fix: - Confirm your eSIM is selected as the Mobile Data line. - Set APN manually as provided by the carrier. - If your plan is data‑only, use OTT apps for calls/messages.

5) “Plan cannot be added” / “Unable to complete cellular plan change” - Cause: Region/IMEI/EID mismatch or unsupported device profile. - Fix: - Ensure you’re on the latest iOS. - Provide your device EID to the provider (Settings > General > About). - Ask the provider to reprovision the eSIM.

6) “Could not activate mobile data network” - Cause: APN or temporary network block. - Fix: - Reenter APN, then reboot. - Toggle Airplane Mode, then test again. - Try manual network selection.

Still stuck? Delete and reinstall the eSIM: - Settings > Mobile Data > tap the plan > Remove eSIM. Re‑add via QR/manual details. Ensure Wi‑Fi is stable during reactivation.

Managing multiple eSIMs on iPhone 15/16

Store many, use two: iPhone 15/16 can store multiple eSIMs and keep up to two lines active at once.
Switch data line quickly: Settings > Mobile Data > Mobile Data > select the plan you need.
Pause a line (don’t delete): Toggle “Turn On This Line” off to keep the profile for later.
Delete when finished: Remove eSIM to tidy your list. Keep a copy of the QR/manual details in case you need to reinstall.

Pro tips for travellers

Pre‑install on Wi‑Fi before you fly, then toggle the line on when you land.
Keep your home line on for SMS codes, but set the travel eSIM as the Mobile Data line.
Save the QR code and manual details offline (Files app/Notes) for airport re‑installs.
If speed dips in crowds, try manual network selection or switch between 5G and LTE.
Hotspot/tethering: Check your plan allows it; if not working, set the APN for Personal Hotspot if provided.

Plan your eSIM by destination

Choose a country or a multi‑country pass based on your route: - Single countries: Esim United States, Esim France, Esim Italy, Esim Spain - Multi‑country: Esim Western Europe, 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.

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.

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.
