Mobile Bands by Region: Will Your Phone Work in the USA, Europe, Asia?

30 Oct 2025

Travelling with your own phone is easy—until it isn’t. Mobile networks use different frequency bands in different parts of the world, and your device must support the right ones to get strong 4G/LTE coverage (and voice, via VoLTE) abroad. If you’ve ever landed to “No service” or painfully slow data, band compatibility was likely the culprit. This guide gives you a traveller-first way to check, fast. You’ll find the key LTE bands by region, simple checklists to confirm compatibility, and pro tips to avoid surprises—plus direct links to regional eSIMs so you can be online the moment you land. Use the band tables to see what matters in the USA, Europe and Asia, then run a quick device check before you buy. If you only remember one thing: you don’t need every band, but you do need the right few for where you’re going.

Mobile bands 101 (the two-minute refresher)

A “band” is a chunk of radio frequency used by mobile networks. LTE bands have numbers (e.g., Band 3, Band 20).
Regions deploy different mixes of bands. Your phone must support the local bands to get 4G data and VoLTE calls.
FDD vs TDD: Some regions (notably China/India) use TDD bands like 40/41. Many phones support both FDD and TDD, but budget or older models may not.
3G/2G shutdowns: The USA has shut down 3G and legacy CDMA. Without VoLTE, calls won’t work. Several countries in Europe/Asia still run 3G, but support is shrinking.
5G is great, but 4G/LTE is still the baseline for reliable coverage. Check LTE first; treat 5G as a bonus.

Pro tip: “Quad‑band” used to mean 2G/GSM compatibility, not LTE. For modern travel, look for LTE/5G band support, not just GSM.

The fast compatibility checklist

1) Find your phone’s supported bands - iPhone: Settings > General > About > Legal > Regulatory, then cross-check on Apple’s specs page. - Android: Settings > About phone > Hardware information, then confirm on the manufacturer’s specs page or model datasheet. - Pro tip: Model numbers vary by region. Verify the exact model (e.g., SM‑S91xB vs SM‑S91xU).

2) Check the destination’s key LTE bands - Use the regional tables below as a quick filter. - Then confirm your specific country on our Destinations page (with device checker).

3) Confirm VoLTE support - USA travel requires VoLTE for calls (3G is off). Ensure your device supports VoLTE and that it’s enabled.

4) eSIM and carrier lock - Ensure your phone is carrier‑unlocked and supports eSIM. - Choose a regional eSIM: for example, Esim United States or Esim Western Europe.

5) Install and test before you fly - Add the eSIM profile, set the APN (if needed), enable data roaming, and run a speed test on arrival.

Pro tips: - You don’t need every band—having the main coverage band(s) plus at least one capacity band usually suffices. - Rural coverage often relies on low‑frequency bands (700/800 MHz like B12/B13/B20/B28). Don’t skip these if you’re leaving big cities.

LTE bands by region: what really matters

North America (USA and Canada)

In the USA, each operator leans on a small set of critical LTE bands. If your device has most of these, you’ll be fine in cities and beyond:

Band

Frequency (approx.)

Where/notes

1900 MHz (PCS)

All carriers; urban capacity

4/66

1700/2100 MHz (AWS)

Core for AT&T, T‑Mobile, Verizon; B66 is an extended AWS

850 MHz

AT&T (also some legacy Sprint/T‑Mobile areas)

12/17

700 MHz (Lower)

AT&T/T‑Mobile coverage band

700 MHz (Upper)

Verizon’s primary coverage band

700 MHz (FirstNet)

AT&T public-safety band; consumer devices increasingly support it

1900+ MHz

T‑Mobile (ex‑Sprint)

850+ MHz

T‑Mobile (ex‑Sprint) coverage supplement

41 (TDD)

2500 MHz

T‑Mobile capacity (ex‑Sprint); strong in many cities

600 MHz

T‑Mobile wide‑area/rural coverage

3G is shut down. VoLTE is mandatory for calls.
For broad USA coverage, aim for Bands 2, 4/66, 5, 12/13, and 71; Band 41 improves capacity in many cities.
Canada broadly uses Bands 2, 4/66, 5, 7, 12/13/17 and 29/30 (DL); coverage varies by operator.

Plan a US trip with Esim United States or a cross‑border plan via Esim North America.

Europe (EU and UK)

Europe’s LTE landscape is remarkably consistent. Most countries use a common “core five” plus 700 MHz:

Band

Frequency (approx.)

Where/notes

2100 MHz

Capacity; widespread

1800 MHz

Core band across Europe

2600 MHz

High‑capacity urban band

900 MHz

Coverage/indoor fill in some networks

800 MHz

Key coverage band (rural/suburban); crucial for reach

700 MHz

Growing rapidly; extra coverage and indoor penetration

32 (DL)

1500 MHz (DL only)

Supplemental downlink in pockets (not required)

38 (TDD)

2600 MHz

Limited use in select markets

For dependable EU/UK coverage: Bands 3, 20 and 28 are the most valuable; Bands 1 and 7 add city capacity.
3G still exists in some countries but is being retired. Rely on LTE and VoLTE.

Asia–Pacific highlights

Asia is diverse. Use this table to prioritise bands by destination cluster:

Country/region

Key LTE bands to have

Notes

China

1, 3, 8, 39/40/41 (TDD)

Heavy use of TDD (B39/40/41) plus B3/B1; ensure TDD support

Japan

1, 3, 8, 11, 18, 19, 21, 28, 41

Local bands (11/21) and coverage bands (18/19); broad support on mainstream flagships

South Korea

1, 3, 5, 7

B3 is central; B1/B5 common; B7 for capacity

India

3, 5, 8, 40, 41 (TDD)

B40 is widespread; B3 core; check VoLTE with your device

SE Asia (SG, MY, TH, ID, VN, PH)

1, 3, 5, 7, 8, 28, 40/41

Common blend; B28 increasingly used for coverage

Australia/NZ

1, 3, 5, 7, 8, 28, 40

B28 is vital for regional coverage; B3/B7 for city capacity

Notes: - Japan can be picky with VoLTE provisioning. Newer global models fare best. - China/India’s reliance on TDD means budget phones that skip Bands 40/41 may struggle for speed. - Australia/New Zealand prioritise Band 28 for range—crucial if you’re driving outside metro areas.

Use our country pages and device checker on Destinations to confirm specifics before buying.

Quick examples: what “good enough” looks like

City‑only USA trip: Bands 2, 4/66 and 12 or 13 will usually carry you; 71 is a bonus for reach.
Pan‑Europe rail trip: Bands 3 + 20 (and preferably 28) for near‑universal coverage; 1/7 for faster city data.
China/India circuit: Ensure TDD Bands 40/41 in addition to 1/3; without them, expect patchier data or slower speeds.

Pro tip: Premium global models (recent iPhone/Pixel/Galaxy flagships) typically include all critical bands for these regions. Mid‑range or region‑specific variants may drop one or two—double‑check.

How to set up your phone and eSIM before you fly

1) Verify compatibility - Match your phone’s LTE bands to the country’s key bands using this guide and Destinations.

2) Pick a regional plan - USA/Canada: Esim North America or country‑specific Esim United States. - Western Europe multi‑city: Esim Western Europe. - Single‑country trips: Esim France, Esim Italy, Esim Spain.

3) Install the eSIM - Add via QR or in‑app; label it (e.g., “Trip eSIM”). - Set it as the mobile data line; leave your home line for calls/SMS if needed.

4) Enable VoLTE and data roaming - iPhone: Settings > Mobile Data > your eSIM > Voice & Data > enable LTE/VoLTE. - Android: Settings wording varies; ensure 4G preferred and VoLTE toggled on.

5) Configure APN if required - Most eSIMs auto‑configure. If speeds are odd, re‑check APN settings provided at purchase.

6) On arrival: test quickly - Toggle flight mode off/on, check bars, run a speed test. Move to a window for initial registration if signal is weak.

FAQs

Q: Do I need every local LTE band to get coverage? A: No. Aim for the main coverage band(s) plus at least one capacity band. In Europe that’s typically 20/28 + 3/7; in the USA it’s 12/13/71 + 2/4/66.

Q: Will my phone make calls in the USA? A: Only if it supports VoLTE and the carrier recognises your device for VoLTE. 3G is shut down. Ensure VoLTE is enabled and consider mainstream devices for best compatibility.

Q: My phone is “GSM unlocked.” Is that enough? A: Not necessarily. “GSM unlocked” doesn’t guarantee LTE band support. Check the specific LTE bands your device supports against the destination’s bands.

Q: What about 5G bands—should I care? A: Treat 5G as a bonus. LTE is the baseline for reliable coverage. If your phone matches the key LTE bands, you’ll be fine; 5G adds speed where available.

Q: How do I find my phone’s exact bands? A: Check the manufacturer’s specs for your precise model number (e.g., on the retail box or in Settings). Cross‑reference with the tables above or use the device checker on our Destinations page.

Q: Will a European phone work in North America (and vice versa)? A: Often yes, but performance varies. Many EU phones lack Band 71 (USA rural) and some USA models lack Band 20 (EU rural). City usage may be fine; rural coverage can suffer.

The bottom line

Match your phone’s LTE bands to where you’re going, prioritise the few that matter, and enable VoLTE. Choose a regional eSIM that fits your itinerary and install it before you fly.

Next step: Check your destination and run a quick device compatibility check on our Destinations page, then pick the right plan (e.g., Esim North America or Esim Western Europe) to travel connected.

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.

eSIM Stuck on “Activating” on Android: 12 Fixes That Work

Travelling with a new eSIM and seeing your Android stuck on “Activating”? You’re not alone. The “esim activating android” loop usually points to a radio, settings, or carrier-service cache issue—not a dead plan. The good news: most activations can be salvaged with a few practical resets and checks you can do in minutes, even at the airport. This guide prioritises fixes that work on the road: cycling Airplane mode, resetting network settings, verifying APNs, and clearing Google Carrier Services cache. You’ll also find steps to re-add the eSIM safely, and quick checks for roaming and network selection.Menus vary slightly by device (Pixel, Samsung, Motorola, OnePlus), but the flow is similar across Android 12–14. Keep your eSIM QR or activation code handy, and stay on reliable Wi‑Fi while activating. For country-ready plans, see our regional pages such as [Esim United States], [Esim France], [Esim Italy], [Esim Spain], [Esim Western Europe] or browse all [Destinations]. Business travellers can also streamline deployments via [For Business].Start with these quick checksBefore deep troubleshooting, confirm the basics:Your device supports eSIM and is carrier-unlocked.Strong, stable Wi‑Fi during installation (avoid captive portals in airports/hotels).Date & time set to Automatic.VPN and Private DNS disabled: Settings > Network & Internet > VPN (Off) and Private DNS (Automatic/Off).Android OS up to date; restart after updating.You are in a covered country/region for your plan.If you carry multiple lines, your travel eSIM is enabled and set as the data line.Pro tip: Some travel eSIMs only activate when you’re physically in the destination country and data roaming is ON. If you’re headed to the US or Canada, check [Esim North America]. For Europe, see [Esim Western Europe].12 fixes for an eSIM stuck on “Activating” (Android)Try these in order. Test after each step.1) Cycle Airplane mode (the fastest radio reset)Pull down Quick Settings.Turn on Airplane mode for 20–30 seconds.Turn it off and wait 1–2 minutes.Open Settings > Network & Internet > SIMs and check the eSIM status.Why it works: it forces a fresh network registration without a full reboot.2) Full restartHold Power > Restart.After reboot, wait 2 minutes before opening any apps.Check eSIM status again.Pro tip: If Wi‑Fi auto-connects to a weak network, temporarily forget it and use a stronger Wi‑Fi or mobile hotspot.3) Ensure data roaming is ON for the eSIMSettings > Network & Internet > SIMs.Tap your travel eSIM.Toggle Data roaming ON.Set Preferred network type to 5G/4G (LTE) or 4G/3G/2G (Auto), not 2G-only.Many international eSIMs require roaming ON even in the country of use.4) Manually select a network, then go back to AutomaticSettings > Network & Internet > Mobile network > Network.Turn off Automatically select network.Pick the listed partner network (e.g., Orange, AT&T, Vodafone) and wait 1–2 minutes.If registration succeeds, switch back to Automatic.This nudges the device to register with an allowed partner when auto-selection stalls.5) Verify and correct APN settingsEven during activation, Android may need the correct APN to complete data attachment.Settings > Network & Internet > SIMs > [your eSIM] > Access Point Names.Compare with the APN provided by your eSIM supplier. Typical fields: - Name: any (e.g., Simology) - APN: as supplied (case-sensitive) - Username/Password: often blank - MCC/MNC: auto-filled; don’t change unless instructed - APN type: default,supl (no spaces) - Authentication: None/PAP per instructionsSave, select the new APN, toggle Mobile data OFF/ON, then recheck activation.Pro tip: If APNs are greyed out, remove any Device Policy/Work Profile temporarily or contact your admin (see [For Business]).6) Clear Google Carrier Services cache (and storage if needed)Carrier Services can hold stale configuration that blocks activation.Settings > Apps > See all apps.Tap Carrier Services.Tap Storage & cache > Clear cache.Try activation. If still stuck: Clear storage, then restart the phone.Also open the Play Store and update Carrier Services to the latest version (see Fix 8).7) Toggle Mobile data and Preferred network typeSettings > Network & Internet > Internet.Toggle Mobile data OFF, wait 10 seconds, then ON.Go to SIMs > [your eSIM] > Preferred network type and switch between 5G/4G and 4G-only. Wait 1 minute after each change.This triggers a new PDP context and often completes activation.8) Update Google Carrier Services and Google Play servicesOpen Google Play Store.Search “Carrier Services” and “Google Play services” and tap Update if available.Restart the phone.Outdated components can cause provisioning loops.9) Reset network settings (safe but thorough)Settings > System > Reset options.Tap Reset Wi‑Fi, mobile & Bluetooth.Confirm (this forgets saved Wi‑Fi, Bluetooth pairings, APNs; it doesn’t erase photos/apps).Reconnect to Wi‑Fi and check eSIM activation.This clears hidden radio and APN conflicts that commonly cause the “Activating” hang.10) Disable SIM auto-switching and set the eSIM as the data SIMOn dual-SIM phones, auto data switching can interfere.Settings > Network & Internet > SIMs.Turn OFF “Switch data automatically” or “Auto data switching”.Set your travel eSIM as Preferred SIM for Mobile data.Temporarily disable the physical SIM if needed.Re-enable your usual SIM after the eSIM is active and roaming correctly.11) Remove and re-add the eSIM profile (with caution)Only do this if you have the QR/activation code and your plan allows reinstallation.Settings > Network & Internet > SIMs > [your eSIM] > Delete/Remove.Restart the phone.Settings > Add eSIM > Use QR code or Enter activation code.Stay on strong Wi‑Fi. Keep data roaming ON after install.Pro tip: Some plans have limited re-downloads. If unsure, confirm via your provider or our [Partner Hub] if you manage eSIMs at scale.12) Check date/time, Private DNS, and VPN one more timeSettings > System > Date & time > Set Automatically (use network-provided time).Settings > Network & Internet > Private DNS > Automatic or Off (not a custom hostname).Settings > Network & Internet > VPN > Disconnect/Remove any VPN.Re-try activation on a different Wi‑Fi network or a mobile hotspot.Even minor clock drift or a strict DNS/VPN policy can block provisioning.After activation: quick test checklistOnce the eSIM shows Active:Toggle Mobile data OFF/ON.Turn Wi‑Fi OFF and load a fast site (e.g., a map).Keep Data roaming ON.Confirm the correct APN is selected.If data is slow or intermittent, try 4G-only temporarily and re-test.If you’re travelling in the US, expect 3G shutdowns—ensure 4G/5G is enabled. See [Esim United States] or broader [Esim North America] options if you plan to cross borders. For multi-country EU trips, [Esim Western Europe] covers popular routes including [Esim France], [Esim Spain], and [Esim Italy].Prevention checklist before you flyVerify device eSIM support and unlock status with your original carrier.Save or print your QR/activation code offline.Know your plan’s activation trigger (on install vs on first connection in-country).Record your device EID and IMEI: Settings > About phone.Update Android, Carrier Services, and OEM apps before departure.If managing teams, pre-stage profiles using [For Business] or via the [Partner Hub].When to contact support (and what to include)If you’re still stuck after all 12 fixes, reach out with:Screenshots of the eSIM status page and any error messages.Your device make/model and Android version.eSIM ICCID (or last 4 digits) and your EID/IMEI.Location (city/country) and tested networks.APN values in use and whether data roaming is ON.Steps you’ve already tried from this guide.This speeds up diagnosis and avoids repetitive back-and-forth.FAQQ: Why is my “esim activating android” stuck at 0% or “Setting up mobile plan”?A: It’s usually a radio registration or provisioning cache issue. Start with Airplane mode, enable data roaming, confirm APN, clear Carrier Services cache, then try network reset.Q: Do I need Wi‑Fi to activate an eSIM?A: Strong Wi‑Fi is recommended for downloading the profile. After install, the first network attachment can use mobile data, but poor Wi‑Fi can stall the process.Q: Should data roaming be ON even if I’m in the destination country?A: Yes. Most travel eSIMs rely on roaming flags even in-country, especially in the US and EU. Keep data roaming ON for the eSIM line.Q: Will resetting network settings delete my eSIM?A: No. “Reset Wi‑Fi, mobile & Bluetooth” does not remove eSIM profiles. It clears saved Wi‑Fi, Bluetooth pairings, and APN customisations.Q: Can I move my eSIM to another phone if activation fails?A: Only if your plan allows re-downloads. Many travel eSIMs are single-use per EID. Check plan terms or contact support before deleting the profile.Q: I installed before flying and it won’t activate abroad. What now?A: In the destination, turn data roaming ON, cycle Airplane mode, attempt manual network selection, verify APN, then clear Carrier Services cache. Some plans only fully activate once you’re physically in-region.Next step: Choose the right plan for where you’re headed.

Approve from the parent device.On flaky Wi‑Fi, temporarily allow downloads over mobile—then switch back.Location not updating:Ensure Location Services and mobile data are on, and low‑power modes aren’t disabling background location for maps/safety apps.Kids need more time/data today:Use a one‑time 30–60 minute extension in Screen Time or Family Link; don’t change the baseline rule.Planning multiple devices or group travel?Families running several child lines benefit from shared data visibility and predictable bundles. If you manage a school trip or youth team, see our solutions For Business for centralised purchasing and support.Travel agents and tour providers can offer pre‑configured child‑safe eSIMs; explore our Partner Hub.FAQsHow early should I set up parental controls before a trip?Do it 3–5 days before departure. You’ll catch any issues on home Wi‑Fi and can pre‑download maps and media.Do controls still work if my child turns off mobile data?Screen time and app limits apply regardless of data. Location sharing and approvals need connectivity, so keep a small data allowance active or rely on regular Wi‑Fi check‑ins.What’s the simplest way to cap data?Put the child on a dedicated travel eSIM, set it as the only Mobile Data line, and enable OS‑level data limits. When the bundle runs out, usage stops.Should I use a VPN on public Wi‑Fi?A reputable VPN can add privacy on open networks. At minimum, use HTTPS sites/apps and avoid sensitive logins on open Wi‑Fi.How do I keep essential apps working during Downtime?Add Maps, Wallet, airline/rail, and your family chat to “Always Allowed” (Apple) or set app‑specific exceptions (Family Link).What if we’re visiting several countries in one trip?Choose a regional plan like Esim Western Europe or Esim North America so you don’t juggle multiple SIMs. Check coverage notes in our Destinations pages.Next step: Choose the right travel plan for your itinerary—start with our region and country guides on Destinations.
