UK ↔ EU Roaming in 2025: What Travelers Pay Post‑Brexit

29 Oct 2025

Planning a 2025 trip between the UK and Europe? Post‑Brexit roaming is no longer one-size-fits-all. “Roam like at home” rules don’t bind UK networks in the EU or EU networks in the UK. Instead, each operator sets its own prices, fair‑use limits and speed policies. For travellers, that means possible daily fees, monthly passes, per‑GB surcharges, or generous inclusions—depending entirely on your plan. This guide explains what UK and EU residents can expect, where the gotchas hide (fair‑use is the big one), and how to avoid bill shock with simple steps and flexible eSIMs. We’ll also compare typical scenarios: a weekend city break, a two‑week holiday and a month‑long workation. If you only remember three things: check your plan’s EU/UK zone and caps, control roaming in your phone settings, and consider a local or regional eSIM to lock in predictable data costs.

The quick answer: uk eu roaming charges 2025 at a glance

UK residents in the EU: Expect either a daily fee (often around £2/day), a monthly/30‑day pass, or “included roaming” with a fair‑use data cap (commonly 12–25 GB). Exceed the cap and you may pay per‑GB surcharges or see speeds throttled.
EU residents in the UK: No EU‑wide mandate to include the UK. Many EU operators keep the UK in their top roaming zone, but some don’t. You may see day passes (€1–€3/day), per‑GB surcharges, or full inclusion with a fair‑use cap similar to EU “roam like at home”.
Calls and texts: Outgoing calls/texts often follow your roaming zone price list; incoming calls may be free or charged depending on your operator’s UK/EU policy.
Speed: Some plans cap roaming at 3G/4G or throttle after a threshold; 5G roaming may require a premium plan.
eSIMs: Local/regional eSIMs can undercut day fees on trips longer than 3–5 days and give you predictable data pricing.

What changed after Brexit?

The EU’s “roam like at home” rules no longer apply to UK networks, and the UK is a third country for EU operators.
Since 2021, UK and EU operators are free to set their own roaming terms for each other’s markets.
Many networks reintroduced fees or limits, but competitive pressure means some still include EU/UK roaming with fair‑use caps.
Consumer protections (spend alerts, bill limits) vary by operator and country; they are not uniform across UK and EU anymore.

Scenario 1: UK resident travelling to the EU

What you may pay

Daily roaming fees: Common on consumer plans; typically applied per day of use. Good for short trips, expensive for longer stays.
30‑day passes: A set fee for a block of days; better value for two‑week+ travel.
Included roaming with caps: Some plans include EU roaming but impose a fair‑use data limit (e.g., 12–25 GB per billing cycle). Exceed it and you may pay per‑GB or face throttling.
Pay‑per‑use: Usually the riskiest; per‑MB or per‑minute rates add up quickly.

Pro tips: - Ask your network if tethering counts towards any separate roaming cap; it often does. - Check whether voicemail retrieval from abroad is chargeable; it often is. Consider turning off voicemail before you go.

Fair‑use nuance for UK subscribers

“Fair‑use” for UK customers in the EU is entirely operator‑defined. Expect: - A monthly roaming data cap (even if you have unlimited data at home). - Reasonable usage rules on duration/ratio (e.g., roaming more than domestic use over a few months may trigger surcharges). - Potential speed management (e.g., priority at home, lower priority when roaming).

A simple pre‑trip checklist (UK → EU)

Confirm your EU roaming zone and pricing: check daily fees, 30‑day passes, per‑GB rates and any voice/SMS charges.
Find your data fair‑use cap and what happens after it (surcharge, throttle or stop).
Set a roaming spend cap or alerts in your account/app.
Update device OS and apps over Wi‑Fi before travel.
In Mobile Data settings, disable background refresh for heavy apps (cloud photos, auto‑updates).
Consider an eSIM for predictable data costs: - Single country: Esim France, Esim Spain, Esim Italy - Multi‑country: Esim Western Europe
Set your phone to Data Roaming ON only for the plan you intend to use (see dual‑SIM tips below).
Save essential offline maps and boarding passes; they’re data‑light insurance.

Scenario 2: EU resident visiting the UK

Does EU “roam like at home” apply in Britain?

No. EU rules apply within the EU/EEA. The UK is outside the regime, so inclusion is up to your operator. Many EU providers still treat the UK as top‑tier roaming with similar pricing to EU roaming, often with a fair‑use cap, but there is no guarantee.

What you may pay

Day passes: Common (€1–€3/day or bundled).
Included roaming with a fair‑use cap: Similar to your EU allowance, but the cap may be lower outside EU/EEA.
Per‑GB or per‑minute charges: If the UK is in a higher zone, costs can be steep.

Pro tips: - Check whether receiving calls in the UK is free on your plan; outside EU rules, some operators charge. - Watch for 5G access; you may get 4G only unless your plan explicitly supports 5G roaming in the UK. - If you’re transiting North America on the same trip, consider a separate regional plan like Esim North America or Esim United States.

Fair‑use policies: what they actually mean

Fair‑use is the main cause of bill surprises in 2025:

Data caps despite “unlimited”: Even if your domestic plan is unlimited, roaming may be capped per billing cycle. After the cap, networks typically charge per‑GB or slow you down.
Duration and residency checks: Some operators monitor how long you roam vs. use at home. Long‑term or predominant roaming can trigger extra charges or warnings.
Tethering and hotspots: Often allowed but count toward the same cap; some plans restrict hotspot use while roaming.
Speed and traffic management: Roaming may be de‑prioritised at busy times; a few plans offer 5G roaming only on premium tiers.

Practical rule: If you rely on maps, ride‑hailing, messaging and light browsing, 5–10 GB per week is comfortable. Streaming video at high resolution eats that quickly; download content over Wi‑Fi.

Bill‑shock prevention checklist

Set a hard spend cap and enable roaming alerts in your account/app.
Turn off voicemail or avoid retrieving messages from abroad if chargeable.
Disable automatic app updates and cloud photo backups on mobile data.
Limit video to Wi‑Fi; pre‑download playlists and shows.
Prefer Wi‑Fi calling or data‑based calls; check what your plan charges for voice roaming in the UK/EU.
Use a local/regional eSIM for data to avoid per‑GB roaming charges and keep your primary SIM for calls/SMS only.
Keep an eye on usage in your phone and your provider’s app; both meters help.
Know emergency numbers: 112 works across the EU; 999/112 in the UK.

eSIMs that beat day fees

For trips longer than a few days, a local or regional eSIM typically wins on cost and control:

Single‑country eSIMs: Ideal for city breaks and fixed itineraries.
Esim France
Esim Spain
Esim Italy
Multi‑country bundles: Great for rail trips or multi‑stop itineraries.
Esim Western Europe
Beyond Europe on the same ticket:
Esim United States
Esim North America
Browse all supported markets via Destinations.

Benefits: - Predictable, prepaid data with clear allowance and validity. - Keep your home SIM active for calls/SMS and 2FA. - Instant setup via QR code; no store visits.

Worked examples: what’s cheaper?

5‑day city break (UK → EU): Daily roaming at ~£2/day ≈ £10 if you only need light data. A 3–5 GB local eSIM is competitive and often faster; choose eSIM if you expect navigation, social and a bit of streaming.
2‑week holiday (EU → UK): Day fees add up. A 10–20 GB eSIM commonly beats daily charges and avoids fair‑use surprises, especially for families tethering tablets.
1‑month workation: Passes or included roaming caps are often exceeded mid‑month. A regional eSIM with a larger allowance is usually most economical and simpler to manage.

How to run dual‑SIM the smart way

Most recent iPhone/Android models support eSIM alongside your physical SIM.

Step‑by‑step: 1. Buy and install your travel eSIM while on Wi‑Fi before departure. 2. Label lines (e.g., “Home” and “Travel”) in your phone settings. 3. Set “Mobile Data” to the Travel eSIM; leave “Default Voice Line” as Home so people can still reach your number. 4. Turn Data Roaming ON for the Travel eSIM, OFF for the Home SIM. 5. Enable Wi‑Fi Calling on your Home SIM if supported to lower call costs when on Wi‑Fi. 6. After the trip, switch Mobile Data back to Home and delete/disable the travel eSIM if it was a one‑off plan.

Pro tips: - Keep iMessage/WhatsApp tied to your home number so contacts don’t lose you. - If your bank uses SMS 2FA, keeping the home SIM active avoids lockouts.

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.

Hotspot & Tethering on eSIM: Limits, Speeds, and Safe Sharing

Travelling with an eSIM and need to get your laptop or tablet online? Turning your phone into a hotspot (or tethering via USB/Bluetooth) is often the most reliable way to work, stream, or map your way through a new city. This guide explains how to set up and optimise hotspot and tethering on eSIM devices, what limits to expect, how to tweak APN settings when hotspot is blocked, and how to keep things secure and cool under load. You’ll also find device-limit guidance, speed expectations, practical VPN advice for laptops, and battery/heat tips drawn from real-world use. Where rules and networks vary by country, we point to the right country pages and Playbooks so you can check local notes before you land. If you just need the bottom line: yes, hotspot works on most eSIMs, but plan rules, device caps, and APN settings often decide how well it works.Planning a trip? Start at Destinations to check local tips.Regional picks: Esim North America, Esim Western Europe, Esim United States, Esim France, Esim Italy, Esim Spain.Hotspot vs tethering: the quick definitionsPersonal hotspot: Your phone creates a Wi‑Fi network others can join.USB tethering: Your phone shares data over a cable to one computer; fastest and lowest latency; charges at the same time.Bluetooth tethering: Low-power, slow; fine for basic chat/email.Tethering vs hotspot: Tethering is the umbrella term; hotspot is usually Wi‑Fi sharing.eSIM doesn’t change the mechanics: if your plan allows it, hotspot/tethering will behave like a physical SIM. The differences come from plan permissions, APN profiles, local carrier policies and device limits.Does your eSIM plan allow hotspot/tethering?Most travel eSIMs allow hotspot, but not all. Some carriers disable tethering on certain APN profiles or cap the number of devices.Checklist before you rely on it: 1. Check the plan description for “tethering allowed” or “hotspot support”. 2. Look for data policy notes on the country/region page (start at Destinations or specific regions like Esim North America or Esim Western Europe). 3. Expect fair use in Europe and some throttling at peak times. If your plan says “mobile use only”, hotspot may be blocked. 4. Corporate travellers: consider a pooled or team plan so you’re not sharing a single phone. See For Business.Tip: If hotspot is off or greyed out as soon as you enable it, it’s often an APN configuration issue. See the APN section below.Set up hotspot on your phone (and fix common snags)iPhone/iPad (iOS/iPadOS)Basic setup: 1. Settings > Mobile Data > toggle Mobile Data on. 2. Tap Personal Hotspot. 3. Turn on Allow Others to Join. 4. Set a strong Wi‑Fi password (12+ characters). Avoid birthdays or simple words. 5. Optional: toggle Maximise Compatibility to use 2.4 GHz (better range, lower speed).If Personal Hotspot is missing or won’t enable, check APN fields: - Go to Settings > Mobile Data > Mobile Data Network. - You may see three APN sections: Mobile Data, LTE Setup (optional), and Personal Hotspot. - Copy the APN value from Mobile Data into Personal Hotspot (username/password too, if present). - Return to Personal Hotspot and try again.Pro tips (iOS): - If devices struggle to join, enable Maximise Compatibility to force 2.4 GHz, then try 5 GHz again later for higher speeds. - USB tether for long work sessions: plug into your laptop and enable Personal Hotspot; macOS/Windows will auto-detect. - Family Sharing can auto-join trusted Apple devices without sharing the password.Android (steps vary by brand, but generally)Basic setup: 1. Settings > Network & Internet (or Connections) > Hotspot & tethering. 2. Tap Wi‑Fi hotspot (or Mobile Hotspot). 3. Set Network name (SSID), Security = WPA2 or WPA3, and a strong password. 4. Toggle hotspot On. 5. Optional: Set AP band to 5 GHz for speed if all your devices support it.If hotspot toggles off instantly or says “Not available”: - Check Data Saver/VPN apps aren’t blocking tethering. - APN profile may be missing the DUN flag (tethering APN). Try: - Settings > Mobile network > Access Point Names. - Create a new APN using the APN details provided with your eSIM. - Under APN type, include: default,supl,dun - Save, select the new APN, toggle flight mode Off/On, then retry hotspot.Note: Some carriers lock APN editing. If you can’t add “dun”, use USB tether (often unblocked) or contact support via your plan page on Destinations.USB and Bluetooth tetheringUSB (iOS/Android): Plug your phone into your computer; enable Personal Hotspot/USB tethering. Best for speed, latency, and power (it charges your phone).Bluetooth: Pair devices; enable Bluetooth tethering. Useful when Wi‑Fi is congested, but speeds are modest.Device limits and realistic speedsDevice caps: - iPhone: typically up to 5 Wi‑Fi clients (plus 1 via USB and 1 via Bluetooth in some cases). Behaviour varies by iOS and device. - Android: commonly up to 10 Wi‑Fi clients, configurable in Hotspot settings. Some models/carriers cap lower.Performance expectations: - The hotspot speed ceiling is your phone’s own mobile data speed. Expect 5–15% overhead for Wi‑Fi sharing. - 5 GHz hotspot usually outperforms 2.4 GHz (less interference), but range is shorter. - USB tether bypasses Wi‑Fi overhead and interference, improving stability and latency—ideal for calls and remote desktop.Pro tips for better throughput: - Place the phone near a window for stronger mobile signal; avoid pockets and bags. - If 5G is weak or causing drops, try 4G/LTE only mode for steadier performance. - Change the hotspot channel (Android) if nearby Wi‑Fi networks are clashing. - Avoid chaining multiple VPNs (phone + laptop). See the VPN section.Using VPN on a laptop over hotspotA VPN can protect traffic on public networks, but it introduces overhead.What works best while travelling: - Prefer modern protocols (WireGuard, IKEv2) over older, heavy options (OpenVPN TCP). Try UDP-based connections for lower latency. - If your corporate VPN is mandatory, enable split tunnelling so only work apps use the VPN; streaming and updates go direct. - Use a kill switch to prevent data leakage if mobile signal drops. - Banking/gambling sites may flag unusual IP geolocation across borders. Temporarily disable the VPN if legitimate services won’t load. - Test your “work stack” (VPN + conferencing + RDP/VDI) on hotspot before you travel.If speeds collapse when starting the VPN: - Try a nearer VPN location. - Switch protocol (WireGuard/IKEv2). - Use USB tether to reduce latency and packet loss.Business teams that need guaranteed performance should consider device-per-person rather than sharing a single hotspot. See For Business for options, and the Playbooks linked from Destinations for country-specific notes.Battery, heat and reliability on the roadHotspot is power-hungry. Add 5G radios, and heat becomes the bottleneck.Practical checklist: - Use USB tether when possible: fastest and charges simultaneously. - If on Wi‑Fi hotspot, keep the phone on a table/stand with airflow; avoid dashboards and direct sun. - Disable unused radios: turn off Bluetooth/NFC if you don’t need them. - Lock the phone to 4G/LTE in weak 5G areas to reduce hunting and heat. - Lower screen brightness; use Low Power Mode (iOS) or Battery Saver (Android). - Keep a power bank handy, or a 20W+ charger for fast top-ups.If the phone overheats: - Pause heavy downloads/updates on connected devices. - Switch to 2.4 GHz (Maximise Compatibility) to reduce RF load. - Move to cooler shade; remove thick cases temporarily.Safe sharing: security and access controlDo: - Use WPA2 or WPA3 with a strong, unique password. - Change the hotspot password after sharing with new people. - Enable automatic turn-off when no devices are connected (Android setting on many models). - On iOS, consider Family Sharing for known Apple devices.Avoid: - Open (password-free) hotspots. - Sharing with strangers or in crowded venues where shoulder-surfing is easy. - Leaving hotspot on when you walk away from your laptop.Extra layer: - Keep your phone and laptop fully patched. - On Windows/macOS, mark the hotspot as “Private/Trusted” only if it’s yours; otherwise keep it “Public” to tighten the firewall.Troubleshooting: common tethering blockers and fixesSymptom: Hotspot setting is greyed out or turns off immediately - Cause: Plan blocks tethering or APN lacks DUN. - Fix: Edit APN (Android) to include APN type default,supl,dun, or copy APN into the iOS Personal Hotspot APN field. If APN editing is locked, try USB tether, then contact support via your plan page under Destinations.Symptom: Devices connect to hotspot but no internet - Cause: Captive portal or exhausted data. - Fix: Open a browser on the phone itself to trigger any network sign-in. Check your remaining data in the app/portal.Symptom: Poor speed on hotspot but good on phone - Cause: Wi‑Fi interference or 2.4 GHz congestion. - Fix: Switch hotspot band to 5 GHz (Android) or disable Maximise Compatibility (iOS).Symptom: VPN disconnects frequently - Cause: High packet loss over Wi‑Fi or marginal 5G signal. - Fix: Use USB tether; lock to LTE; change VPN protocol to WireGuard/IKEv2.Symptom: Laptop won’t see the hotspot - Cause: Hidden SSID or band mismatch. - Fix: Ensure SSID is broadcast; try the other band; forget and re-add the network on the laptop.Country notes and planningRules and performance vary by market and carrier. Before you fly: - United States: 5G coverage is broad but varies by city and band. Check Esim United States for plan notes and any hotspot caveats. - Western Europe: Generally friendly to tethering on mainstream plans; watch fair-use policies. Start with Esim Western Europe. - France/Italy/Spain: Review local network compatibility and APN notes in Esim France, Esim Italy and Esim Spain. - Regional coverage maps and Playbooks are linked from Destinations.Partners and travel teams can access implementation guidance and updates via the Partner Hub.Pro tips from the roadPrioritise USB tether for calls, RDP and VPN-heavy work.Keep a short, quality USB‑C or Lightning cable in your bag; cheap cables cause flaky tethering.Set laptop updates to “metered connection” to avoid background downloads chewing your data.Share with fewer devices. Each extra device adds overhead and contention.If you must share widely (family/team), consider a dedicated travel router that connects to your phone’s hotspot and manages the rest—then place the phone somewhere with the best signal.FAQQ: Do all eSIM plans allow hotspot/tethering? A: No. Most travel plans do, but some block it. Check your plan details on Destinations or the regional page (e.g. Esim North America, Esim Western Europe).Q: How many devices can I connect to my phone’s hotspot? A: iPhone typically supports around 5 Wi‑Fi devices; Android often allows up to 10 (varies by model and carrier). More devices mean less bandwidth per user.Q: Will using a VPN on my laptop slow things down? A: A bit. Expect additional latency and some throughput loss. Use USB tether, a modern protocol (WireGuard/IKEv2), and split tunnelling to keep speeds usable.Q: My hotspot toggle is greyed out on eSIM. What can I do? A: Ensure your plan allows tethering. Then check APN: on iOS, copy the data APN into the Personal Hotspot APN field; on Android, include “dun” in APN type (default,supl,dun). If APN editing is locked, try USB tether or contact support via your plan page.Q: Is 5G always better for hotspot? A: Not always. Weak 5G can fluctuate and overheat your phone. Locking to LTE can deliver steadier performance for calls and uploads, especially indoors.Q: What’s the safest way to share with a friend? A: Use WPA2/3 with a strong password, share via QR code, and change the password afterwards. Turn the hotspot off when done.Next step: Choose your destination, confirm hotspot support on the plan page, and note any APN specifics in the Playbooks. Start at Destinations.
