Japan eSIM for Tourists: Identity Requirements, App Calling & Network Notes (2025)

30 Oct 2025

Thinking about a Japan eSIM for your 2025 trip? Here’s what actually matters. Japan’s rules distinguish sharply between tourist-friendly data eSIMs and resident mobile plans with a phone number. Identity checks vary depending on where and what you buy; hotspotting sometimes gets limited; and network behaviour (VoLTE, 5G, APNs) can affect your experience more than you expect. This guide covers the japan esim tourist requirements in plain English, plus practical steps to set up app calling, avoid tethering surprises, and pick the right network profile for cities, mountains, and shinkansen corridors. If you’re mapping a wider itinerary, see Japan alongside other countries on Destinations and consider mixing regional profiles like Esim North America or Esim Western Europe for onward legs.

Tourist vs resident mobile plans in Japan

Tourist eSIMs (data-only)
Designed for short stays.
Usually no Japanese ID or local address needed when purchased from international providers.
No local phone number; use apps (LINE/WhatsApp/FaceTime) for calls and messages.
Validity is fixed (e.g., 7/15/30 days) with a set data allowance or “unlimited” with fair-use limits.
Resident plans (voice/SMS + data)
Offered by Japanese carriers/MVNOs for long-term residents.
Require ID verification and typically a Japanese address and payment method.
Provide a Japanese number, native voice calling, and SMS.
Contract commitments and cancellation rules may apply.

Practical takeaway: Most travellers should pick a data-only tourist eSIM and keep their home SIM active for banking codes and fallback calling.

Japan eSIM tourist requirements: identity and activation

What ID do tourists need?

Buying from international travel eSIM sellers
Typically no Japanese ID required.
You purchase with a card, receive eSIM via email/app, and activate by scanning a QR code.
Some vendors run light fraud checks (e.g., 3-D Secure) but no passport capture.
Buying at Japanese airports/shops or vending machines
Airport counters often ask to see a passport even for data-only SIM/eSIMs (retailer policy).
Voice/SMS-capable SIMs require identity verification and often a residence card/address. These are not designed for short-term visitors.
Online Japanese MVNOs
Increasingly use eKYC (passport selfie + data). Many still won’t issue voice/SMS to short-stay visitors.

Pro tips: - If you only need data, an international tourist eSIM avoids most ID friction. - If you must have a Japanese number, plan for in-person verification and be ready for rejection without a residence card.

Activation basics and what gets checked

Activation usually happens the moment the eSIM profile connects in Japan, not when you scan the QR code (check your vendor’s policy).
Some plans auto-start on first network attach; others start on the purchase date. Read the start/expiry fine print.
Payment methods commonly accepted: major cards and sometimes PayPal/Apple Pay/Google Pay. Japanese retailers may prefer credit card or cash.

Where ID rules bite in practice

Emergency calling: Data-only eSIMs do not support native emergency calls (110/119). See App Calling below for workarounds and why keeping a voice-capable line matters.
Hotel Wi‑Fi and public hotspot logins: Some portals ask for SMS verification to a mobile number. Without a Japanese number, use email-based login or your home SIM for the OTP.
App registrations: A few services in Japan require a domestic number. Most travellers can rely on LINE/WhatsApp without one.

App calling in Japan: how to stay reachable without a local number

You won’t get a Japanese phone number with a typical tourist eSIM. Here’s how to handle calls:

Use app-based calling and messaging:
LINE is Japan’s default. Create or update your account on your home number before travel.
WhatsApp, FaceTime, Google Meet, Skype, Signal all work normally over mobile data.
Keep your home SIM active for:
Bank OTPs and two-factor codes.
Occasional inbound calls to your usual number (consider roaming charges).
Wi‑Fi Calling on your home SIM:
If your operator supports Wi‑Fi Calling in Japan, you may be able to place/receive regular calls using Wi‑Fi or your eSIM’s data. Charges are per your home plan; check rates before you rely on it.
Emergency calls:
VoIP apps may not connect you to 110/119 or may route incorrectly. If you need emergency services, use a phone with native cellular voice service, ask a nearby venue to call, or use hotel/rail staff.

Pro tips: - For long app calls, switch video off to save data and improve stability. - Share your app IDs with travel companions before you land to avoid setup delays on airport Wi‑Fi.

Hotspotting and tethering limits

Most tourist eSIMs allow personal hotspot tethering, but there are caveats:

Plan and APN policy:
Some profiles block tethering at the network or APN level even if the phone shows the toggle.
“Unlimited” plans may throttle hotspot traffic sooner than on-device usage.
Device behaviour:
iPhone may hide Personal Hotspot until the carrier/APN settings update; toggling Mobile Data off/on or installing a carrier settings update can help.
Android may require entering a specific APN to enable tethering; check your plan’s APN instructions.
Fair usage:
Daily “unlimited” often means high-speed data up to a cap (e.g., 2–5 GB/day) then speed-limited. Heavy video streaming over hotspot will trigger throttling quickly.
What to avoid over hotspot:
Cloud backups and OS updates can silently consume tens of GB. Disable background updates while tethering.

Quick test: 1. After activation, connect a laptop to your hotspot. 2. Load a few domestic sites (e.g., transit maps) and a video at 480p. 3. If speeds stall or the laptop can’t reach pages while your phone can, the plan likely restricts tethering.

Network notes (2025): coverage, 5G, device bands

Primary networks:
NTT Docomo: Broadest rural reach (mountains, coastal routes), excellent nationwide LTE; robust 5G in cities.
KDDI au: Strong nationwide 4G/5G; great urban and intercity coverage.
SoftBank: Very good in cities and along transport corridors; 3G retired; 4G/5G focus.
Rakuten Mobile: Rapidly expanding but still patchier outside major metros; seldom used by tourist eSIMs.
What travel eSIMs use:
Most tourist profiles attach to KDDI au or SoftBank; some offer Docomo. Few use Rakuten.
3G shutdown:
3G service is largely retired. Expect 4G/5G only. Ensure your device supports VoLTE if you intend to use a voice-capable line.
5G reality:
NSA 5G (n77/n78) is common; mmWave (n257) is city hotspot–style. Don’t plan your trip around mmWave.
Device compatibility:
Recent iPhones and premium Androids support Japan’s LTE (Bands 1/3/8/18/19/21/28/41) and 5G (n77/n78; some n257).
Your phone must be carrier-unlocked and eSIM-capable.
Dual-SIM tip:
Set your Japan eSIM as “Mobile Data” line and keep your home SIM for calls/SMS. Disable data roaming on the home SIM to avoid bill shock.

Step-by-step: install and use a Japan travel eSIM

Check your device: - Confirm it’s unlocked and supports eSIM. Update iOS/Android to the latest version.
Buy the plan: - Choose a data allowance that matches your usage and trip length. Verify hotspot support and fair-use policy.
Schedule activation: - If your plan auto-starts on install, wait until you’re about to depart. If it starts on first connection, you can pre-install at home.
Install the eSIM: - Scan the QR or use the app. Name it “Japan” for clarity.
Configure data lines: - Set “Japan” as the default for Mobile Data. Keep your home SIM as default for Calls/SMS if needed.
Enable data roaming on the Japan eSIM: - Required for it to attach in Japan. Keep roaming OFF on your home SIM.
APN and hot-spot check: - If instructed, enter the APN. Test Personal Hotspot with a quick connection to another device.
On arrival: - Toggle Airplane Mode once. Wait for the network to register (1–2 minutes). If no data, restart, then re-check APN and data roaming settings.

Pro tips: - Download offline maps for your first city in case of airport congestion or signal dead spots. - Add your chosen calling apps (LINE/WhatsApp) to the phone’s “Unrestricted data” list to prevent background throttling.

Quick checklist before you buy

Do you need a Japanese phone number?
If yes, be prepared for in-person ID checks and likely rejection as a short-stay visitor. Otherwise, choose a data-only tourist eSIM.
Identity friction tolerance:
Prefer no-ID purchase? Buy from an international travel eSIM provider rather than an airport kiosk.
Tethering needs:
Verify hotspot is allowed and note any fair-use caps.
Data forecast:
Navigation + social + a few video calls = roughly 0.8–1.5 GB/day. Adjust for streaming or heavy uploads.
App calling plan:
Install LINE/WhatsApp and share contact details ahead of time. Keep home SIM active for OTPs.
Device readiness:
Unlocked, eSIM-capable, VoLTE-enabled. Carry a secondary connectivity option (hotel Wi‑Fi or a backup plan) if you work on the road.

FAQ

Do tourists need ID to buy a Japan eSIM?

For international travel eSIMs (data-only), you usually don’t need Japanese ID—just a payment method and email. Airport counters and Japanese retailers commonly request a passport, and voice/SMS SIMs require full ID checks and often a residence card.

Can I get a Japanese phone number with an eSIM as a visitor?

Generally no. Voice/SMS plans with Japanese numbers are aimed at residents and require ID, a local address, and often a domestic payment method. Tourists should use data-only eSIMs plus app calling.

Does hotspotting work on tourist eSIMs?

Often yes, but not always. Some plans or APNs restrict tethering, and “unlimited” data commonly includes hotspot throttling after a daily cap. Test hotspot on arrival and avoid heavy streaming or system updates over tethering.

Which network will my travel eSIM use in Japan?

Most tourist eSIMs use KDDI au or SoftBank; some offer NTT Docomo. Each has excellent urban coverage; Docomo typically wins in remote/rural areas. Rakuten is less common for tourist plans.

Will LINE and WhatsApp work normally on a data-only eSIM?

Yes. Messaging and calls work over mobile data. Set them up before travel, keep video off for long calls to save data, and add the apps to your device’s “unrestricted data” list.

Can I keep my home SIM active for SMS while using a Japan eSIM?

Yes. Set the Japan eSIM as your data line and leave your home SIM for calls/SMS. Turn off data roaming on the home SIM to avoid charges. If your carrier supports Wi‑Fi Calling abroad, you may take and place normal calls over the Japan eSIM’s data, billed by your home plan.

Next step: Compare Japan alongside other countries and pick the right plan on Destinations.

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.

Move eSIM to a New Android Phone (Samsung/Pixel/OnePlus)

If you’re upgrading your Android phone or carrying a new device for travel, moving your mobile plan across should be straightforward. With eSIM, that can mean either a direct device‑to‑device transfer (supported on some models and networks) or a quick reactivation using your carrier’s SM‑DP+ details or QR code. This guide explains both paths for Samsung, Google Pixel and OnePlus, and helps you decide which one to use. We’ll also cover dual‑SIM caveats that catch travellers out, and the exact situations where re‑downloading your eSIM is required. Whether you’re keeping your home number for banking OTPs and adding a travel eSIM for data, or consolidating everything on a new handset, follow the steps below and you won’t be left without service on the way to the airport. Planning a trip? Explore local and regional eSIMs on our Destinations page, including options like Esim United States and Esim Western Europe.Quick reality check: “transfer” vs “reactivate”There is no user‑accessible “export/import file” for eSIM profiles on Android due to GSMA security.Transfers work only when both devices and your carrier support the built‑in eSIM migration feature.Otherwise, you’ll reactivate on the new phone by scanning a QR code or entering SM‑DP+ details; your carrier re‑downloads the profile from their server.Keep both devices and a Wi‑Fi network handy. If your old phone is lost or broken, skip straight to the SM‑DP+ reactivation method.Before you start: compatibility and preparation checklistMake sure the following is true to avoid interruptions:Your new phone is eSIM‑capable and carrier‑unlocked.Android version: ideally Android 13 or newer (Android 14 improves transfer on Pixels).Battery ≥ 50% on both phones; connect to stable Wi‑Fi.Bluetooth enabled and both devices are nearby (for transfer).You know your eSIM’s SM‑DP+ server and activation code (check your email/order, carrier app/portal, or support). The code often looks like LPA:1$smdp.plus.example$ACTIVATIONCODE.Find your EID (eSIM ID) in Settings > About phone > Status (some carriers ask for it).If your carrier enforces “one active eSIM per number,” be ready to remove or deactivate the eSIM on your old phone when instructed—ideally only after the new one is live unless support tells you otherwise.Back up your messaging apps if needed (RCS/WhatsApp is account‑based but verify backup settings).Travelling soon? You can keep your home line for OTPs and add a travel data eSIM such as Esim North America or Esim Spain on the new device.Option A: Device‑to‑device eSIM transfer (when available)This is the easiest path when it appears. It requires support from your device, Android version and carrier. If you don’t see a transfer option, jump to Option B.Samsung (One UI 5.1 or later)On recent Samsung models, eSIM transfer is built into SIM Manager.1) On the new Samsung: - Go to Settings > Connections > SIM manager > Add eSIM. - Choose Transfer SIM or Transfer eSIM from another device if prompted.2) On the old Samsung: - When a transfer prompt appears, follow on‑screen instructions to approve the transfer. You may also navigate to Settings > Connections > SIM manager > Your eSIM > Transfer to another device if asked.3) Keep both devices unlocked, on Wi‑Fi and close together. Wait for the process to complete.Notes: - Smart Switch does not move eSIM profiles; use SIM manager transfer only. - If your carrier doesn’t support transfer, Samsung will direct you to use a QR/SM‑DP+ activation instead.Google Pixel (Pixel 6 and newer on Android 13/14)Newer Pixels offer eSIM transfer for participating carriers, especially on Android 14.1) On the new Pixel: - Settings > Network & internet > SIMs (or Mobile network) > Add SIM > Download a SIM instead. - If you see Transfer from another device, select it.2) On the old Pixel: - Approve the transfer when prompted.If the transfer option is missing or shows “No eligible SIM,” proceed with SM‑DP+ reactivation.OnePlus (OxygenOS 13/14)Most OnePlus models support eSIM but typically do not offer device‑to‑device transfer. Expect to use QR/SM‑DP+ reactivation (see Option B). If a transfer option appears on your device and carrier, follow on‑screen steps as above.Pro tips for transfersKeep mobile data off during transfer and use Wi‑Fi to avoid interruptions.If you have multiple eSIM profiles, transfer one at a time.After transfer, test calls, SMS and data. Then remove the eSIM from the old phone if required by your carrier.Option B: Reactivate the eSIM on your new phone (QR/SM‑DP+)If transfer isn’t supported, re‑download the eSIM profile from your carrier’s server.What you need: - SM‑DP+ address, activation code, and (optionally) a confirmation code. - Your EID (sometimes required to bind the profile to your new device).Generic Android steps1) On the new phone: - Open Settings: - Samsung: Connections > SIM manager > Add eSIM. - Pixel: Network & internet > SIMs > Add SIM > Download a SIM instead. - OnePlus: Settings > Mobile network > SIM management > Add eSIM. 2) Choose Scan QR code. If you don’t have a QR, pick Enter details manually and input the SM‑DP+ server and activation code from your carrier. 3) Stay on Wi‑Fi while the profile downloads. When installed, set it as your preferred line for data, calls and SMS as needed.When SM‑DP+ reactivation is requiredMoving between different brands (e.g., Samsung to Pixel, Pixel to OnePlus).Your carrier doesn’t support Android’s transfer feature.The old phone is lost, broken or wiped.You’ve changed numbers or are porting service.The profile on the old phone is locked or corrupted.Business or MDM‑managed lines where security policy blocks transfer.If your carrier limits one active eSIM per line, they may ask you to remove the old one first or will automatically suspend it when the new profile activates.Common places to find your QR/activation detailsThe original fulfilment email or order page.Your carrier or provider app.Web account portal under “Manage eSIM.”Support chat—have your EID ready.Heading to France or Italy? You can set up your travel data line in advance with Esim France or Esim Italy and activate it the moment you land.About “export/import” of eSIM profilesThere is no manual export/import file for eSIM on Android.“Transfer” is a controlled hand‑off between devices when supported.Otherwise, you “import” by re‑downloading from the SM‑DP+ server using your activation code.If anyone asks you to share an eSIM file, treat it as a red flag.Dual‑SIM and travel caveats (read before you fly)Dual‑SIM flexibility is brilliant for travellers, but a few settings matter:One data connection at a time: Android supports DSDS (dual SIM dual standby) but only one SIM can carry mobile data concurrently. Set your travel eSIM as the data SIM.Roaming control: Turn off data roaming on your home SIM to avoid surprise charges, while keeping calls/SMS on if you need OTPs.5G/VoLTE per SIM: 5G and VoLTE availability can be restricted when two SIMs are active. On some models, 5G drops to 4G when both SIMs are enabled. Test locally before you travel.Wi‑Fi Calling and RCS: These features are provisioned per SIM. If they don’t work on the new device, toggle them off/on or re‑provision by briefly switching the device to airplane mode and back on Wi‑Fi.Visual Voicemail: May require your carrier’s app or re‑provisioning on the new phone.Stored vs active eSIMs: Many phones can store multiple eSIM profiles (e.g., 5–8) but only keep one or two active at once. Name them clearly (e.g., “Home UK,” “Spain data”).Priority for calls/SMS: Choose the correct default SIM for outgoing calls and messages, or set “Ask every time” to avoid using the wrong line.Planning multiple countries? Consider a regional plan like Esim Western Europe instead of juggling several single‑country eSIMs such as Esim Spain.Troubleshooting: errors and roadblocksNo transfer option available:Update both phones to the latest software.Log into the same brand account if required (Samsung account for some transfers).If it still doesn’t appear, use SM‑DP+ reactivation.“No eligible SIM” or “Carrier not supported”:Your carrier doesn’t support transfers. Use the QR/SM‑DP+ method or contact support to unlock/reissue an eSIM.Activation fails or stalls:Use Wi‑Fi only; turn off mobile data during download.Toggle airplane mode or reboot.Clear Carrier Services app cache (Pixels/stock Android).Confirm the SM‑DP+ address and activation code characters (watch for 0/O and 1/I mix‑ups).Wait 10–15 minutes and try again—back‑end provisioning can lag.Carrier says the eSIM is “already in use”:Remove/deactivate the old profile and ask the carrier to reset/reissue the activation.Need the EID:Find it in Settings > About phone > Status > EID. Share it with support if requested.Lost or wiped old phone:Contact your carrier to revoke the old eSIM and issue new activation details. You do not need the old device to activate on the new one.If you’re setting up for a work trip and need multiple lines for staff, our team can help streamline provisioning via For Business. Partners and resellers can access tools and support via the Partner Hub.Example: setting up a travel eSIM alongside your home lineKeep your home eSIM active for calls/OTP.Add a travel data eSIM like Esim United States before you fly.On arrival, set the travel eSIM as the data SIM, keep data roaming off on your home line.Test WhatsApp/Maps and a quick speed test on Wi‑Fi first, then on mobile data.If your phone drops to 4G with two SIMs active, that’s normal on some models; if you need 5G, temporarily disable the inactive SIM.FAQ1) Can I export my eSIM profile to a file and import it on the new phone? - No. For security, Android does not allow exporting eSIM profiles to files. Use device‑to‑device transfer (if supported) or re‑activate via QR/SM‑DP+.2) Do I need my old phone present to transfer eSIM? - Only for device‑to‑device transfers. If the old phone is unavailable, ask your carrier to reissue activation details and use the SM‑DP+ method.3) Will dual‑SIM affect my 5G or battery life? - Possibly. Some phones limit 5G when two SIMs are active. Dual standby also uses slightly more power. If you need maximum speeds, disable the unused SIM temporarily.4) How many eSIMs can I store? - It varies by model (often 5–8 stored). Typically only one or two can be active at the same time. Check your device specs.5) Will WhatsApp, banking and OTPs still work after I move my eSIM? - WhatsApp links to your account, not the SIM, but ensure you keep your number and have backups. For OTPs, keep your home line active for SMS; confirm roaming is off if you want to avoid data charges.6) Does eSIM reactivation cost money? - Some carriers charge a small fee to reissue or move an eSIM. Policies vary—check your provider’s terms before you start.Where to nextSet up your travel line now so it’s ready when you land.

SIM‑Swap & Account Takeover: Prevention Tips for Travellers

Staying connected abroad shouldn’t put your identity at risk. Yet SIM‑swap fraud and account takeovers spike when people travel. Why? Attackers know you’ll be in transit, juggling time zones, relying on roaming, public Wi‑Fi and unfamiliar numbers. If they convince a carrier to reassign your number (a SIM‑swap), they can intercept SMS one‑time codes and reset your logins—often within minutes. This guide gives you practical, step‑by‑step defences you can set up in under an hour, plus what to do if you ever see suspicious “No Service” or sudden account alerts mid‑trip.We’ll focus on the highest‑impact moves for sim swap protection travel: enabling carrier account and port‑out PINs, turning on real‑time account alerts, tightening password hygiene and phishing detection, and knowing exactly when to contact your carrier. We’ll also show how travel eSIMs, used alongside your primary number, can reduce exposure without breaking your banking or messaging flows. Whether you’re off to the US, France, Italy or Spain, explore reliable eSIM options via Destinations and keep your number—and identity—yours.What is SIM‑swap and why travellers are targetedA SIM‑swap (also called port‑out fraud) happens when someone persuades your mobile carrier to move your number to a SIM or eSIM they control. Once that happens, they can: - Receive SMS one‑time passwords (OTP) meant for you - Reset email, bank, crypto, travel or social accounts - Trigger password resets using your number as a recovery method - Approve fraudulent transactions that rely on SMS codesTravellers are prime targets because: - You’re harder to reach and slower to respond to alerts - Roaming can mask “No Service” blips and strange SMS messages - You’re more likely to use public Wi‑Fi and unfamiliar networks - You may depend on SMS for banking while abroadPro tip: SIM‑swap is often the second step. The first is phishing—stealing enough info (name, number, DOB, last digits of ID) to convince a carrier. Stopping the phish often stops the swap.Before you fly: lock down your number and accountsTreat your mobile number like a bank account. These steps take 30–60 minutes and block most SIM‑swap attempts.1) Add carrier security controlsSet a strong carrier account password and memorable passcode.Enable a port‑out PIN or number lock/freeze (names vary by carrier). This prevents transfers without the PIN—even if someone knows your personal details.Turn on SIM PIN on your device. This protects your physical SIM if your phone is lost or stolen. Note: it won’t stop a remote carrier‑initiated SIM‑swap by itself.Disable or PIN‑protect voicemail, especially “reset by voicemail” features.Pro tip: Save your carrier’s fraud and international support numbers offline (notes app, paper, or password manager). If you lose service, you’ll need another line to call them.2) Move critical accounts off SMS 2FASwitch your email, cloud storage, bank, social and travel accounts to an authenticator app, hardware key or passkeys.Remove your phone number as a recovery method where possible; add a second email instead.Download and print backup codes for top accounts; store them securely.Pro tip: Your email is the “master key”. Secure it first with an authenticator or passkey before anything else.3) Turn on real‑time alertsCarrier: login attempts, SIM changes, password changes, new lines added.Email: new logins, forwarding rules added, recovery methods changed.Bank/fintech: new device logins, password changes, large transactions, payee changes.4) Upgrade password hygieneUse a password manager to create unique, 16+ character passphrases.Enable Travel Mode (if your manager supports it) to carry only what you need.Update OS and apps; enable device‑wide screen lock and Find My/remote wipe.Smarter connectivity choices on the roadUsing a travel eSIM can reduce risk by separating your data from your primary number.Keep your primary line active but restricted to calls/SMS only if you still need bank texts. Use a travel eSIM for data and apps.Alternatively, keep your primary number off (or on “no data”) and shift logins to app‑based authentication.Prefer secure messaging apps tied to your account rather than your phone number for travel coordination.Explore regional options: - United States: Esim United States - France: Esim France - Italy: Esim Italy - Spain: Esim Spain - Multi‑country: Esim Western Europe or Esim North AmericaPro tip: eSIM reduces the risk of physical SIM theft, but it doesn’t eliminate carrier‑level SIM‑swaps. Keep those carrier PINs and locks enabled.Spot the red flags: phishing and social engineering on the moveExpect tailored lures while travelling. Common examples: - “Your roaming bill exceeds $500. Verify now.” - “We’ve blocked your SIM for unusual activity. Confirm to restore.” - “Bank alert: new device login in [your destination]. Enter the code we just sent.” - Fake delivery or airline messages with urgent links - “Apple/Google/Meta: your account will be disabled. Appeal here.”How to verify safely: - Do not click links in unsolicited texts/emails. Open the carrier/bank app directly or type the URL. - Check sender details. Short codes vary by country; inconsistency is a clue. - Look for subtle misspellings, odd grammar or mismatched domains. - Treat unexpected one‑time codes as a sign someone is trying to log in as you.Pro tip: If a caller claims to be your carrier and asks for your port‑out PIN or full password, hang up and call the official number you saved earlier.When to contact your carrier (and exactly what to say)Contact your carrier immediately if any of the following occur: - Sudden “No Service” on your primary line while others have signal - Multiple “Your SIM has been changed/activated” messages - Password reset texts you didn’t request - Banks/email warn about login attempts from your home country while you’re abroadWhat to ask: - “Place an immediate freeze/number lock on my line; disable port‑out.” - “Reverse any SIM change and issue a new SIM/eSIM tied to my account.” - “Add a permanent port validation PIN on file; require it for any changes.” - “Notify me of all account changes by email and app push.” - “Confirm recent changes and provide a record of the activity.”Pro tip: From abroad, contact via carrier app over Wi‑Fi or your travel eSIM data. Keep your identity docs and account PIN ready.Step‑by‑step: If you suspect a SIM‑swap right now1) Get online another way - Use hotel Wi‑Fi, a companion’s hotspot or your travel eSIM for data. - Avoid logging in over unsecured public Wi‑Fi without a trusted VPN.2) Lock your number - Log into your carrier account; change the password and enable any number lock/port‑freeze features. - If you can’t log in, call the carrier’s fraud line and ask them to freeze/restore the line.3) Secure your “master” accounts - Change your email password; enforce authenticator or passkeys. - Review account recovery settings; remove phone number as a recovery method if safe to do so.4) Stop the financial fallout - Open your banking apps directly; review recent transactions and devices. - Temporarily freeze cards or accounts if anything looks off; call the bank from the app or listed number.5) Rotate other critical logins - Cloud storage, password manager, messaging, crypto, travel/airline accounts.6) Document and follow up - Note times, alerts, and support ticket numbers. - Ask the carrier to investigate and to keep the port‑freeze in place.After you return: keep the locks onLeave the port‑out PIN/number lock enabled permanently.Keep SMS as a last‑resort recovery only; prefer authenticators/passkeys.Review your phone number’s usage in accounts and remove where not essential.Maintain alerts on carrier, email and banking accounts.Revisit your eSIM setup for your next trip via Destinations.For teams on the move, centralise travel connectivity and security policies with For Business.

The real protection is carrier PINs/number locks, strong account passwords and non‑SMS 2FA.Q2) What’s the difference between a SIM PIN and a carrier port‑out PIN? - A SIM PIN protects the SIM on your device. A port‑out PIN (or number lock) is stored with your carrier and is required to move your number to another SIM/eSIM. You need both.Q3) Should I use SMS for two‑factor authentication while travelling? - Only if you must. Prefer authenticator apps, hardware keys or passkeys. If you rely on SMS (e.g., for your bank), enable carrier locks and alerts and keep your primary line reachable but tightly controlled.Q4) I’ve lost service abroad. How do I tell if it’s a SIM‑swap or normal roaming issue? - Check: do other travellers have service? Did you receive SIM change/reset texts or emails? Can you still use data on your travel eSIM? If yes to these clues, contact your carrier’s fraud line immediately and lock your number.Q5) Will a travel eSIM affect my banking texts? - No—your primary number remains your primary. A travel eSIM just handles data. You can keep the primary line active for SMS, or switch banks to app‑based approvals before travel.Q6) I’m travelling across multiple countries. What’s the simplest secure setup? - Use a regional eSIM (e.g., Esim Western Europe or Esim North America) for data, keep carrier locks on your primary number, and rely on authenticator/passkeys instead of SMS wherever possible.Next step: Plan your route and add a regional eSIM with built‑in flexibility.
