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

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

2

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

5

850 MHz

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

12/17

700 MHz (Lower)

AT&T/T‑Mobile coverage band

13

700 MHz (Upper)

Verizon’s primary coverage band

14

700 MHz (FirstNet)

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

25

1900+ MHz

T‑Mobile (ex‑Sprint)

26

850+ MHz

T‑Mobile (ex‑Sprint) coverage supplement

41 (TDD)

2500 MHz

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

71

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

1

2100 MHz

Capacity; widespread

3

1800 MHz

Core band across Europe

7

2600 MHz

High‑capacity urban band

8

900 MHz

Coverage/indoor fill in some networks

20

800 MHz

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

28

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.

Heading to Paris, Rome or Barcelona? Check country specifics and pick a regional plan: - France: Esim France - Italy: Esim Italy - Spain: Esim Spain - Multi‑country trip: Esim Western Europe

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

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.

Is eSIM Secure? Myths, Risks & How to Stay Safe

Is eSIM Secure? Myths, Risks & How to Stay Safe

Travellers love eSIM for instant setup, no queues and easy switching. But many still ask a simple question: is eSIM safe? In short: yes—when you buy from a reputable provider and follow a few basic security steps, eSIM is as safe as (and often safer than) a traditional plastic SIM. It uses GSMA-standard, carrier-grade security, with profiles delivered over encrypted channels and protected by your phone’s hardware.That said, no connectivity method is magically immune to risk. The biggest day‑to‑day threats to travellers are not eSIM itself but account takeover, dodgy QR codes, and—by far the most common—unsafe public Wi‑Fi. This guide cuts through the noise, explains how eSIM security really works, and gives you practical checklists to stay protected on the road. If you’re planning multi‑country travel, explore our regional options like Esim Western Europe or Esim North America, or browse all Destinations.eSIM security, in plain EnglishAn eSIM is a secure chip inside your phone that stores your mobile plan as a digital profile. Instead of inserting a plastic SIM, you download a profile from a secure server (known as an SM-DP+). Your phone and the server verify each other using certificates, then exchange encrypted data to install the profile.Key points that matter for safety: - No physical card to steal, lose, or swap. - Profiles are bound to your device’s secure hardware. - Provisioning uses mutual authentication and encryption based on GSMA standards used by mobile operators worldwide. - You control activation, deactivation, and deletion on your device settings.Is eSIM safe? The short answerYes. eSIMs use operator‑grade security and reduce several risks associated with plastic SIMs.Why eSIM can be safer than a physical SIM: - Harder to steal or swap: There’s no tiny card to remove. Many eSIM transfers require device unlock and/or account verification. - Encrypted delivery: Profiles are provisioned over secure channels; the QR code is just a pointer, not the profile itself. - Faster control if lost: You can remotely erase your phone (which removes eSIM profiles) and suspend service via your carrier promptly.Where the real risks are: - Social engineering (SIM swap via your carrier account, not via “hacking” the eSIM itself). - Malicious QR codes or fake eSIM vendors. - Insecure public Wi‑Fi, which remains a far bigger everyday threat than mobile data.Common myths, debunked“eSIMs are easy to hack”Reality: There’s no public evidence of widespread eSIM profile “hacking” on modern devices. Attacks we hear about are usually account takeovers (convincing a carrier to port your number) or device theft. Keep your carrier/Apple/Google accounts locked down with strong, unique passwords and multi‑factor authentication (MFA).“Scanning a QR code is unsafe”The QR code typically contains the address of the secure server (SM-DP+) and an activation code. The sensitive bits still travel through an encrypted, authenticated session between your phone and the operator. The risk isn’t the QR format—it’s scanning codes from untrusted sources. Only use codes from your provider’s website/app or official email.“eSIM can be cloned”Cloning traditional SIMs required physical access and exploits. eSIM profiles are bound to device hardware and provisioned with mutual authentication, making cloning impractical for opportunistic attackers. Your bigger risk is someone taking over your carrier account, not copying your eSIM.“eSIM drains battery or tracks me more”No. eSIM is simply the way your device stores carrier credentials. Network behaviour, not eSIM itself, affects battery and privacy. As with any mobile plan, your operator sees the usual network metadata.“Public Wi‑Fi is fine if there’s a password”A café password does not equal end‑to‑end security. Open or shared‑password Wi‑Fi can be spoofed (“evil twin”), intercepted, or used to inject malicious captive portals. Mobile data via eSIM avoids most of these pitfalls.The real risks (and how to lower them)Account takeover (SIM swap)Risk: An attacker convinces your carrier to move your number to their device.Reduce it:Add a carrier account PIN and enable MFA.Use unique passwords stored in a password manager.Be wary of phishing that targets your email, Apple ID, Google account, or banking.Fake eSIM sellers and malicious profilesRisk: Phishing sites selling bogus “eSIMs,” or QR codes that lead you to install unknown profiles.Reduce it:Buy from reputable providers and official marketplaces.Confirm the web domain and payment gateway before purchase.Avoid Telegram/WhatsApp “resellers” without verifiable credentials.QR code interception or tamperingRisk: Using public PCs or shared screens to display codes; others scan your code.Reduce it:Access codes privately on your own device.Never share activation codes or order emails.Lost or stolen phoneRisk: Thieves may use your data/number if the phone remains unlocked.Reduce it:Set a strong device passcode and enable biometric unlock.Turn on Find My (iOS) / Find My Device (Android).Remote‑lock/erase immediately; contact your carrier to suspend service.Public Wi‑Fi risksRisk: Data interception, malicious hotspots, credential theft.Reduce it:Prefer mobile data via eSIM for banking, booking, and email.If Wi‑Fi is unavoidable, use a trusted VPN and disable auto‑join for open networks.Pro tip: When you arrive, enable “Allow Mobile Data Switching” (iOS) or equivalent dual‑SIM settings carefully, so your primary line isn’t used for roaming by mistake.A traveller’s security checklistBefore you flyBuy your eSIM from a trusted provider. Explore country packs like Esim United States, Esim France, Esim Italy or Esim Spain, or regional bundles such as Esim Western Europe and Esim North America. You can compare all options under Destinations.Secure your accounts: - Set a carrier account PIN and enable MFA. - Turn on MFA for email, Apple ID/Google, and banking.Update your phone to the latest OS.Set a strong device passcode; enable biometrics.Prepare backups (iCloud/Google) and enable Find My/Find My Device.When installing your eSIMUse a trusted network (mobile data or your home Wi‑Fi).Scan the QR code from your provider only; avoid screenshots in group chats.Confirm the Data Roaming toggle for the correct line to avoid bill shock.Keep your primary number as “Calls & SMS” only (if you need it) and route data through your travel eSIM.On the roadPrefer eSIM mobile data over public Wi‑Fi for sensitive tasks.If you must use Wi‑Fi:Verify the network name with staff; beware of lookalikes.Use a VPN; avoid logging into critical accounts on captive portals.Turn off auto‑join for open networks.Monitor usage and plan validity in your device settings.If your phone is lost/stolen: remote‑lock and erase, then contact your provider to suspend the line.When you head homeDelete unused travel eSIM profiles in Settings.Review your accounts and change any passwords used on shared networks.Keep your provider receipts and emails for future trips.Pro tip: Dual‑SIM setups are ideal. Keep your home number for calls/SMS (data off), and run data on your local eSIM for cheaper, safer connectivity.eSIM vs public Wi‑Fi: which is safer?For day‑to‑day travel, mobile data via eSIM is generally safer than public Wi‑Fi: - Air interface encryption: 4G/5G encrypt traffic between your phone and the tower. While telecom‑grade threats exist, opportunistic interception on mobile networks is far less common than Wi‑Fi sniffing. - Fewer “evil twin” attacks: It’s trivial to mimic “Free Airport Wi‑Fi”; it’s not trivial to mimic a mobile network your phone will trust. - Less captive portal risk: Wi‑Fi portals can inject scripts or trick you into entering credentials. Mobile data doesn’t have this layer.When to consider Wi‑Fi: - Large downloads or video calls where you trust the network (e.g., hotel room with unique password, enterprise WPA2‑Enterprise). Even then, a VPN adds protection.Bottom line: For most travellers wondering “is eSIM safe?”, the bigger question is “is this Wi‑Fi safe?”. If in doubt, stick to eSIM data.For business travellers and teamsMobile security is a team sport: - Standardise on eSIM data for travel devices to reduce Wi‑Fi risk. - Use MDM/EMM to enforce passcodes, remote‑wipe and VPN. - Require MFA on all corporate accounts and set carrier account PINs for employees. - Centralise purchasing for predictable costs and vetted vendors. See Simology For Business. - Agencies, TMCs, and resellers can streamline secure eSIM distribution via our Partner Hub.Where to buy securelyChoose reputable providers with transparent plans, clear activation steps and responsive support: - Country eSIMs: Esim United States, Esim France, Esim Italy, Esim Spain. - Regional bundles: Esim Western Europe, Esim North America. - Explore all Destinations to match your route and budget.Pro tip: Install the eSIM before you fly so you’re online the moment you land—no airport Wi‑Fi needed.FAQQ: Is eSIM safer than a physical SIM? A: In many ways, yes. There’s no card to steal, profiles are tied to device hardware, and provisioning uses encrypted, authenticated channels. The major risk remains account takeover, not the eSIM tech itself.Q: Can someone hack my eSIM by scanning my QR code? A: Not if you keep it private. The QR code points your phone to a secure server; the actual profile is delivered over an encrypted, mutually authenticated session. Treat the code like a password—don’t share or display it publicly.Q: What if my phone is lost or stolen while travelling? A: Immediately use Find My/Find My Device to lock and erase the phone, which removes the eSIM profile. Then contact your provider to suspend or transfer the line. A strong device passcode and biometrics limit misuse.Q: Is public Wi‑Fi safe if I use HTTPS? A: HTTPS helps, but Wi‑Fi still carries risks: malicious hotspots, DNS tampering, captive portal tricks, and misconfigured apps. For sensitive tasks, mobile data via eSIM is typically safer. If Wi‑Fi is unavoidable, use a trusted VPN.Q: Can I use eSIM and a physical SIM at the same time? A: Yes. Most modern phones support dual‑SIM (one physical + one eSIM, or dual eSIM). You can set calls/SMS on one line and data on the other—ideal for keeping your home number active while using a local data plan.Q: Does eSIM affect battery life or privacy? A: Not inherently. eSIM is just how your plan is stored. Battery life depends on network conditions and usage; privacy is governed by your device settings and operator policies, similar to a physical SIM.Next step: Plan your trip with the right regional or country eSIM—start with our full list of Destinations.

Partner Onboarding Checklist: Branding, Legal, Sandbox, and Go‑Live

Partner Onboarding Checklist: Branding, Legal, Sandbox, and Go‑Live

Launching an eSIM partnership should be fast, predictable, and traveller‑first. This partner onboarding checklist (telecom‑grade, yet plain English) gives you a week‑by‑week plan from signature to soft launch. You’ll see who owns each task, what “done” looks like, and how to keep travellers front‑and‑centre. Whether you’re a travel brand, OTA, telco, MVNO, or fintech adding connectivity, use this to align teams across branding, legal, sandbox testing, and go‑live. Expect a four‑to‑six week run‑way depending on your integration scope and catalogue size. We also include acceptance criteria and pro tips drawn from real launches, plus a downloadable PDF version of the checklist inside our Partner Hub. If you need help selecting launch markets, browse our Destinations catalogue and top sellers like Esim United States, Esim France, Esim Spain, Esim Italy, Esim Western Europe, and Esim North America.Who this checklist is forTravel brands and OTAs adding ancillary connectivity revenueTelcos/MVNOs white‑labelling travel eSIMFintechs, banks and loyalty programmes bundling roamingWorkplace and events platforms providing temporary connectivitySystems integrators building on behalf of the aboveIf you’re scoping this project, share this article with Commercial, Legal, Product/Engineering, Brand/Marketing, Finance, Support Ops, and Data teams on day one.Week‑by‑week onboarding planEach week includes owners and acceptance criteria. Use the downloadable PDF from the Partner Hub as your live tracker.Week 0 (Pre‑flight): Decide scope and prepareOwners: Commercial, Product, BrandKey tasks: - Define your launch catalogue (countries/regions, data sizes, validity). Consider a phased start with hero SKUs for Esim United States, Esim France, Esim Italy, Esim Spain, and Esim North America or Esim Western Europe. - Choose integration: Hosted checkout, API, or both (for web vs app). - Nominate an internal project owner and a weekly stand‑up cadence. - Request access to the Partner Hub and sandbox credentials. - Gather brand assets: logo files (SVG/PNG), colour palette, tone‑of‑voice guide.Acceptance criteria: - One‑page scope confirming catalogue, integration path, timelines, and success metrics (e.g., time‑to‑activation < 60s; NPS ≥ 60). - Partner Hub access confirmed for relevant team members.Pro tip: - Traveller‑first pricing wins. Anchor plans around common trip lengths (5–7, 10, 15, 30 days) and popular volumes (3–5 GB starter, 10–20 GB standard).Week 1: Contracts and complianceOwners: Legal, Commercial, Finance, InfoSecKey tasks: - Execute MSA and service schedules; confirm territory restrictions and brand use. - Complete KYC/KYB and tax forms (as applicable). - Sign DPA and confirm data processing roles. Define breach notification pathways. - Share security posture: data retention, logging, access controls. - Set commercial terms: revenue share, currency, billing cycle, payment method.Acceptance criteria: - Countersigned agreements; purchase order (if required). - DPA and security questionnaire completed and approved. - Billing profile configured; test invoice generated and validated.Pro tip: - Keep privacy notices simple. Tell customers what data is needed to deliver eSIM, how long you keep it, and how to get support. Link to your policy at checkout.Week 2: Branding and catalogue buildOwners: Brand/Marketing, Product, Content, CXKey tasks: - Approve co‑branding and logo placement. Define naming conventions (e.g., “Simology eSIM – United States 5 GB / 30 days”). - Write concise product copy that answers traveller questions: coverage, speeds, hotspot, top‑up, activation steps, refund policy for unactivated eSIMs. - Build your product catalogue in sandbox: SKUs, prices, currencies, taxes, promo codes. - Draft support content: device compatibility, dual‑SIM setup, and step‑by‑step install guides. - Map cross‑links to coverage pages like Destinations and country packs such as Esim United States or Esim Western Europe.Acceptance criteria: - Copy and imagery approved; SKU list frozen for UAT. - Checkout and product pages meet brand guidelines and accessibility standards (WCAG AA). - Internal CX playbooks drafted and searchable.Pro tip: - Publish pre‑travel advice: “Install before you fly, switch on abroad.” It cuts first‑day roaming stress and inbound support.Week 3: Sandbox integration and testingOwners: Engineering, QA, ProductKey tasks (API or hosted checkout): - Generate sandbox API keys; set IP allow‑list and webhook endpoints. - Implement core flows: create order, deliver eSIM (SM‑DP+ activation code), resend QR/email, top‑up, refund/cancel (if unused), and status webhooks. - Implement device checks to display “eSIM‑compatible only.” Offer guidance for iOS/Android. - Build error handling and retries for transient network timeouts. - Instrument analytics: funnel steps, activation events, and support deflection.Test cases to run: - Create and fulfil orders for hero SKUs (e.g., US 5 GB, Western Europe 10 GB). - Delivery methods: QR email, deep link, and manual code. - Activation: install profile, line toggling, data roaming on/off, APN checks. - Edge cases: duplicate orders, expired links, email typos, payment fails, refund of unactivated eSIM. - Latency thresholds: order to code < 3s; webhook delivery < 5s (p95). - Observability: logs contain correlation IDs; PII masked.Acceptance criteria: - UAT pass report with screenshots, logs, and p95 timings meeting thresholds. - No P1/P2 defects open; alerting in place for failures > 1% in any step. - Support can reissue codes/QRs from console without engineering help.Pro tip: - Test on both platforms and multiple OEMs. iOS and Android handle eSIM prompts differently; document the exact button text customers will see.Week 4: Support, operations, and reportingOwners: Support Ops, CX, Finance, DataKey tasks: - Define SLAs: first response, resolution, refund of unactivated eSIMs. - Build macros for top queries: “Does my phone support eSIM?”, “How do I install?”, “No data after landing.” - Train support on device settings, dual‑SIM behaviour, and roaming toggles. - Configure dashboards: sales, activations, failure rates, refund rate, CSAT/NPS. - Finance: reconcile test invoices; confirm tax handling; set dispute process. - Incident management: on‑call rota, severity matrix, comms templates.Acceptance criteria: - Knowledge base live; macros tested end‑to‑end. - SLA adherence tracked; weekly ops review scheduled. - Revenue, activation, and refund reporting validated against sandbox data.Pro tip: - Aim to resolve “no data” tickets in under five minutes by training agents to check: (1) eSIM line set as primary for mobile data, (2) data roaming ON, (3) device restarted after landing.Week 5: Go‑live and hypercareOwners: Project Lead, Engineering, Marketing, Support OpsKey tasks: - Switch to production keys; repeat smoke tests on a single low‑risk SKU. - Final price check, tax, and currency confirmation. - Roll out tracking pixels/SDKs with consent. - Update support/KM links to production. - Soft launch to 5–10% of traffic or private cohort. - Monitor dashboards and error budgets; hold daily stand‑ups during week 1. - Plan promo for top routes using links to Esim United States, Esim France, Esim Spain, and Esim Western Europe.Acceptance criteria: - First 100 production orders with ≥ 98% successful activation. - Refund rate for unactivated eSIMs ≤ 1% in week 1. - No unresolved P1/P2 issues for 72 hours.Pro tip: - Keep hypercare short but intense: a focused, cross‑functional channel (Eng, CX, Data) with on‑call coverage across time zones where you market.Roles and responsibilities (RACI‑lite)Commercial: scope, pricing, revenue targets, relationship managementLegal/Compliance: MSA, DPA, KYC/KYB, data governanceProduct/Engineering: integration, sandbox, observability, reliabilityBrand/Marketing: naming, copy, assets, campaign planSupport Ops/CX: SLAs, playbooks, tooling, trainingFinance: billing, tax, reconciliation, disputesData/Analytics: dashboards, KPIs, experimentation frameworkAcceptance test pack: what “ready” meansUse this cut‑down checklist before go‑live: - Catalogue: all SKUs priced, taxed, translated (if applicable), and visible - Delivery: QR and manual code arrive within 60 seconds; deep link opens correctly - Install: profile installs on recent iOS and Android; APN pre‑configured - Activation: data attaches abroad within 60 seconds of landing - Controls: pause/resume data line; hotspot works (if plan permits) - Error handling: friendly guidance for incompatible devices and failed payments - Refunds: unactivated eSIM refund path works in < 2 minutes - Analytics: funnel steps tracked; correlation IDs propagate from order to activation - Security: webhook signatures verified; PII masked in logs; access restricted - Support: agents can find a customer, reissue QR, and send the correct install guideCatalogue tips: start focused, grow fastStart with a small, high‑demand set (US, EU, UK). Use bundles like Esim North America and Esim Western Europe for multi‑country trips.Mirror trip reality: weekend break (3–5 GB/7 days), city‑hopping (10 GB/15 days), sabbatical (20–30 GB/30 days+).Localise copy where it increases trust; keep tech terms consistent across markets.Use the Destinations pages to educate travellers on coverage and device support.Governance and cadenceWeekly stand‑up during build, daily stand‑up during hypercareA single owner for scope, risk, and timelinesClear “no‑go” criteria (e.g., activation success < 95%, webhook failure > 2%)Monthly post‑launch review: funnel, NPS, refunds, catalogue updatesFrequently asked questions1) How long does the Simology partner onboarding take? Most partners go live in 4–6 weeks. Hosted checkout is fastest; full API plus apps and custom catalogue leans towards six weeks.2) Do we need developers to launch? Not strictly. You can launch with hosted checkout and brand configuration. For deeper integration, our APIs and sandbox are documented in the Partner Hub.3) Which destinations should we launch first? Pick high‑volume routes for your customers. Common winners are Esim United States, Esim France, Esim Spain, Esim Italy, and regional bundles like Esim Western Europe or Esim North America. Browse full coverage on Destinations.4) How do we test eSIM without travelling? Use sandbox orders to simulate fulfilment and activation. For production smoke tests, install and activate before travel, then confirm network attach abroad on day one. Document device‑specific steps for iOS and Android.5) What branding controls do we have? You control naming, copy, and presentation within agreed guidelines. Co‑branding ensures consistency and trust for travellers. Assets and examples are available in the Partner Hub.6) What about data protection and refunds? We provide a DPA and secure processing. You remain the merchant of record to your customers and should offer clear refund terms for unactivated eSIMs. Avoid storing activation codes in clear text; mask PII in logs.Download the checklistA printable, week‑by‑week PDF with tasks, owners, and acceptance criteria is available inside the Partner Hub.
