Secure Messaging Abroad: iMessage, WhatsApp, Signal — Best Practices

Travelling adds friction to your private chats: new SIMs, patchy roaming, sketchy Wi‑Fi and the constant risk of loss or theft. This guide distils what actually matters for secure messaging travel across iMessage, WhatsApp and Signal. You’ll learn how to keep end-to-end encryption intact while changing networks and devices, how to avoid account takeovers during SIM swaps, how to set up encrypted backups you can actually restore, and when to use disappearing messages. We’ll also cover dual‑SIM/eSIM roaming so you can keep your home number for authentication while using a local data plan without bill shock.

If you only do three things before you fly: lock your accounts with registration/2‑step verification, enable encrypted backups (or turn backups off if you can’t encrypt), and keep your primary number reachable for re‑activation codes using a travel eSIM for data. Everything below shows you exactly how.

The essentials: how secure are iMessage, WhatsApp and Signal?

  • End-to-end encryption (E2EE): All three encrypt message content in transit and on servers.
  • Backups are the weak link:
  • iMessage: On-device is E2EE. If you sync with iCloud, enable Apple’s Advanced Data Protection (ADP) to keep iCloud Messages end‑to‑end encrypted; otherwise Apple holds keys.
  • WhatsApp: Chats are E2EE, but you must turn on E2EE backups to protect iCloud/Google Drive backups.
  • Signal: No cloud backups. You can create local encrypted backups (Android) with a passphrase.
  • Metadata: Who you talk to and when is more exposed than message content (highest protection on Signal; WhatsApp and iMessage retain more metadata).
  • Device security matters: A strong device passcode/biometrics and encrypted storage are non‑negotiable.
  • SMS fallback is not secure: Avoid sending SMS/MMS when data is spotty; ensure apps don’t silently fall back.

Pro tip: Keep mobile data via a travel eSIM to maintain E2EE reliably instead of hunting for risky public Wi‑Fi. See Esim France, Esim Spain or Esim Italy if you’re heading to Europe.

Before you fly: secure messaging travel checklist

Do these at home on a stable connection with access to your primary number.

iMessage/FaceTime (Apple)

  1. Update iOS/iPadOS/macOS to the latest version.
  2. Settings > Your Name > Password & Security: - Turn on two‑factor authentication for your Apple ID. - Consider Advanced Data Protection for end‑to‑end encrypted iCloud data (store recovery key or set a recovery contact).
  3. Settings > Messages: - Ensure iMessage is On. - Send & Receive: Add your Apple ID and your phone number. Prefer using your Apple ID for reachability while travelling.
  4. Settings > Messages > Send as SMS: Leave On for emergencies, but note SMS isn’t encrypted; watch for green bubbles.
  5. Optional for high‑risk users: iMessage Contact Key Verification (iOS 17.2+). Verify contacts and receive alerts if keys change.

Pro tips: - On dual‑SIM, choose which number iMessage uses in Settings > Messages > Send & Receive. Keep your home number linked but use data on your travel eSIM. - Avoid signing out of Apple ID while abroad; it can trigger re‑verification you may not receive if your home SIM is offline.

WhatsApp

  1. Update WhatsApp.
  2. Settings > Account > Two‑step verification: - Turn on and set a unique PIN. Add an email for recovery. This is your shield against SIM‑swap takeovers.
  3. Settings > Chats > Chat backup: - Turn on End‑to‑end encrypted backup. - Set a strong backup password or store the 64‑digit key securely. Lose it and your backup is irrecoverable.
  4. Settings > Account > Security alerts: - Turn on Security notifications to be alerted when contacts’ security codes change.
  5. Multi‑device: - Consider linking a secondary device before travel (Linked devices). If your primary is lost, you can still access chats on companions.

Pro tips: - Never share your WhatsApp 6‑digit code. WhatsApp support will never ask for it. - If connectivity is unreliable, disable automatic media downloads to reduce data use.

Signal

  1. Update Signal.
  2. Profile > Settings > Account: - Registration lock/PIN: Enable. This prevents someone registering your number on another device without the PIN.
  3. Backups: - iOS: No cloud backups. Transfers require device‑to‑device or QR migration. - Android: Settings > Chats > Chat backups: Create an encrypted local backup; write down the 30‑digit passphrase and store it offline.
  4. Safety numbers: - Open each critical contact > Verify safety number (scan QR or compare digits). Re‑verify after device changes.
  5. Privacy: - Enable Sealed Sender and always‑relay calls if you want to reduce metadata exposure. - Turn on disappearing messages by default for travel chats.

Pro tips: - Signal doesn’t store your chats in the cloud. Test your restore process before you go. - Use a screen lock inside Signal for an extra layer (Settings > Privacy > Screen lock).

Device and carrier hygiene

  • Set a strong device passcode, enable biometrics, and turn on “Erase data after 10 failed attempts” if available.
  • Enable Find My (Apple/Google) and test remote lock/wipe.
  • Ask your carrier to add a SIM‑swap/port‑out lock before travel.
  • Photograph and securely store your SIM/eSIM details and QR codes.

Dual‑SIM and eSIM: roam smart, keep your number safe

Travellers increasingly use dual‑SIM phones with a physical home SIM for identity/OTP and a travel eSIM for data. Done right, you get cheap data without breaking your secure messaging.

  • Keep the home number active for SMS re‑verification while avoiding data roaming fees:
  • iPhone: Settings > Mobile Data:
    • Set your travel eSIM as “Mobile Data”.
    • Turn off “Data Roaming” on the home line.
    • Leave Calls/SMS enabled on the home line so you can still receive OTPs.
  • Android: Settings > Network & Internet > SIMs:
    • Use the travel eSIM for data; disable data on the home SIM; keep SMS on.
  • iMessage:
  • In Send & Receive, ensure your Apple ID is selected so messages can continue over data even if your phone number changes status.
  • WhatsApp and Signal:
  • Both tie identity to your phone number. Keeping the home SIM reachable prevents account reactivation headaches.

Pro tip: Use regional data plans so you don’t swap eSIMs at each border. For example, Esim Western Europe covers multiple countries; for transatlantic trips, pair it with Esim North America.

For destination‑specific coverage and pricing, see Destinations or pick plan pages like Esim United States, Esim France, Esim Spain or Esim Italy.

Account transfer and device loss: minimise risk

If your phone is lost or stolen:

  • General steps (immediately)
  • Use Find My/Find My Device to lock or erase.
  • Contact your carrier to suspend the line to block OTP interception.
  • Move your number to an eSIM or replacement SIM as soon as possible.
  • WhatsApp
  • Get a new SIM with the same number and install WhatsApp to re‑register; this logs out the old device.
  • If you cannot get a SIM quickly, email support@whatsapp.com with the subject “Lost/Stolen: Please deactivate my account” including your number in full international format.
  • Restore from your end‑to‑end encrypted backup using your password/key.
  • Signal
  • Once you have your number back, install Signal and register; Registration Lock will require your PIN (good).
  • On Android, restore from your local encrypted backup with your passphrase.
  • Ask contacts to verify safety numbers again.
  • iMessage
  • Remove the device from your Apple ID at appleid.apple.com.
  • If necessary, deregister your phone number from iMessage at Apple’s deregistration page so new SMS/messages reach you once you switch devices.

Pro tips: - Don’t publish your travel dates and number changes publicly; it aids social‑engineering. - Store your backup passwords/keys offline (paper or a secure password manager with offline access).

Backups, sync and what to encrypt

  • iMessage
  • Best security: Enable Advanced Data Protection so Messages in iCloud stay end‑to‑end encrypted. Keep your recovery key/contact safe.
  • If you can’t use ADP, consider turning off Messages in iCloud during sensitive travel to reduce exposure, but you’ll lose cross‑device message sync.
  • WhatsApp
  • Always enable end‑to‑end encrypted backups with a strong password or 64‑digit key.
  • Test a restore before you leave so you know the password works.
  • Avoid third‑party “transfer” tools that may break security.
  • Signal
  • iOS: Use Signal’s device‑to‑device transfer when replacing phones; it’s encrypted and local.
  • Android: Use the built‑in encrypted local backup only; keep the passphrase offline.

General rule: If a backup isn’t end‑to‑end encrypted with a key only you know, assume your chat content could be exposed.

Disappearing messages and minimising metadata

  • Turn on disappearing messages for travel chats:
  • WhatsApp: Per chat > Disappearing messages > set a short timer (e.g., 24 hours) and “Default message timer” for new chats.
  • Signal: Per chat or global default; add “View‑once” for sensitive media.
  • iMessage: No true disappearing messages. Consider sending via Notes collaboration or avoid persistent media; delete threads you no longer need.
  • Limit message previews on lock screen:
  • Show “Only when unlocked” to prevent shoulder‑surfing.
  • Reduce metadata:
  • Prefer Signal for highly sensitive contacts.
  • In WhatsApp, keep “Last seen/Online” limited to “Nobody” or “My contacts”.
  • Avoid large group chats that leak membership and activity patterns.

Pro tip: Disappearing messages don’t prevent screenshots or backups by your contacts. Share only what you’re comfortable losing control of.

Public Wi‑Fi vs mobile data

  • Prefer mobile data for secure messaging. E2EE protects content on any network, but captive portals and rogue hotspots can still trick you into risky behaviour and leak metadata.
  • If you must use Wi‑Fi:
  • Validate the network name with staff.
  • Use a reputable VPN, especially on shared or open networks.
  • Disable auto‑join for public SSIDs and forget networks after use.

Travel eSIM data is usually the simplest, safest path. Choose regional plans like Esim Western Europe or country plans such as Esim United States. Teams and frequent travellers can streamline provisioning via For Business or explore partnership options in our Partner Hub.

How to set up secure messaging for travel: a quick start

  1. Update your phone OS and all messaging apps.
  2. Lock your accounts: - iMessage: Turn on two‑factor; consider ADP. - WhatsApp: Enable two‑step verification and security notifications. - Signal: Enable Registration Lock (PIN).
  3. Secure your backups: - WhatsApp: Turn on E2EE backups and record the password/key. - Signal (Android): Create and store the encrypted backup + passphrase. - iMessage: Enable ADP or turn off Messages in iCloud if you can’t.
  4. Configure dual‑SIM: - Set travel eSIM for data; keep home SIM for SMS; disable home data roaming.
  5. Set privacy defaults: - Disappearing messages on (Signal/WhatsApp). - Lock‑screen previews off or “When unlocked”.
  6. Test the recovery path: - Restore a WhatsApp backup on a spare device. - Verify Signal safety numbers with a trusted contact. - Confirm you can receive an SMS on the home line while data uses eSIM.

FAQ

Q: Will iMessage work abroad without SMS? A: Yes, iMessage uses data. However, re‑activation can require an SMS. Keep your home SIM able to receive texts while using a travel eSIM for data.

Q: Is WhatsApp secure enough for travel? A: With two‑step verification and end‑to‑end encrypted backups enabled, yes for most travellers. For maximum privacy (less metadata), prefer Signal.

Q: Can I switch phone numbers while travelling? A: Avoid changing the number tied to WhatsApp/Signal mid‑trip; it triggers re‑registration. If you must, use the in‑app “Change Number” (WhatsApp) and notify contacts; re‑verify safety numbers on Signal.

Q: Can I use WhatsApp on two phones? A: Yes. You can link a second phone as a companion device. For resilience, link it before travel so you’re not locked out if your primary is lost.

Q: Do disappearing messages make me bulletproof? A: No. They reduce residual data but don’t stop screenshots or photos. Treat them as cleanup, not a guarantee.

Q: Does a VPN make messaging more secure? A: It doesn’t add encryption to E2EE chats, but it protects against rogue Wi‑Fi and hides traffic from local networks. Still prefer mobile data when possible.

Next step: Pick a regional eSIM to keep your secure messaging online without roaming fees. Start with Destinations or choose a bundle like Esim Western Europe.

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.

The clock starts when the first line in the pack activates data on‑network.Rollover: Unused GB do not roll over after expiry.Step-by-step: set up in minutes1) Choose your region- Browse Destinations. Pick the United States, Western Europe, North America, or a single-country pack.2) Build your Family Pack- Select the number of lines (2–5) and validity window. Add any expected top-ups now or later.3) Checkout- Pay once for the whole pack. You’ll receive QR codes and invite links for each member.4) Invite your family- Share each member’s QR code or invite link. They install their eSIM over Wi‑Fi in Settings.5) Activate on arrival- When you land, turn on the new eSIM’s data. The pack validity starts from the first line to go on‑network.6) Set controls- In the pack dashboard, set per-line caps and alerts. Pause a line any time and unpause with one tap.Parental controls that actually helpKeep kids connected for maps and messaging without runaway usage.Admin controls in the Simology pack: - Set a per-line data cap (e.g., 3 GB for each child).- Pause a line temporarily (e.g., at night).- Disable hotspot/tethering for specific lines if needed.- Turn off roaming for a child’s line after you return home.On-device tips: - iPhone (iOS): Settings > Mobile Data > select the travel plan > enable Low Data Mode; use Screen Time to limit high‑usage apps.- Android: Settings > Network & Internet > SIMs > select the travel eSIM > set Data Saver; set data warning/limit under Data usage.- Both: Disable background app refresh for photo backup apps until on hotel Wi‑Fi; keep automatic cloud photo sync off when roaming.Checklist for parents: - Install all eSIMs at home.- Set per-line caps before travel day.- Agree family rules: upload photos on hotel Wi‑Fi; maps/music are fine on cellular.- Show kids how to toggle Wi‑Fi Assist/Smart Network Switch off to avoid accidental cellular use.When to choose a Family Pack vs individual plansChoose a Family Pack when: - 2–5 travellers are on the same itinerary.- You want one shared pool with predictable costs and controls.- You prefer a single checkout and centralised management.Choose individual plans when: - Travellers are splitting up for different countries/lengths of stay.- One person needs significantly more data than the rest (consider a Family Pack plus one high‑GB individual plan).Planning a team offsite or school trip? Our business controls and consolidated billing may fit better—see For Business.Coverage and where it worksUnited States: Nationwide coverage with 4G/5G in major cities. See plan details on Esim United States.Western Europe: Designed for multi-country travel—check supported countries and fair use on Esim Western Europe.North America: US, Canada, Mexico in one pack—see Esim North America.Single-country Europe: Explore specifics for Esim France, Esim Italy, and Esim Spain.For everything else, browse Destinations to match your itinerary.Partners and travel plannersIf you’re a tour operator, creator, or agency wanting to bundle Family Packs into holiday packages, join our Partner Hub for referral tools and co‑branded materials.FAQs1) Which phones work with Family Packs?Any eSIM‑compatible iPhone or Android handset. Most recent iPhones (XS or newer) and many flagship/mid‑range Androids support eSIM. Each traveller needs an unlocked device.2) Can I mix iOS and Android in one pack?Yes. The shared pool and admin controls are platform‑agnostic.3) Can I add a line after purchase?Yes, up to a maximum of five lines per pack. New lines inherit the pack’s remaining validity and shared pool.4) What happens if we run out of data?Data stops when the shared pool reaches zero. Add a top‑up (e.g., +10 GB) in a few taps; it becomes available instantly.5) Do unused GB roll over or can I extend validity?Unused GB do not roll over. To extend your stay, either add another pack or schedule a second pack to start when the first ends.6) Will WhatsApp and iMessage keep my number?Yes. Your phone number stays tied to your primary SIM; the eSIM is for data. Apps like WhatsApp and iMessage continue to use your existing number.The small, useful printSpeeds depend on network conditions, device, and location. 5G is available in select areas.Hotspot is supported on most networks but may vary; you can disable it per line in the admin controls.Per-line caps help manage usage but won’t limit data consumed while a device is offline from reporting; allow a small buffer if you need a strict cap.Taxes may apply in some regions.

eSIM Profiles 101: SM‑DP+, LPA, EID & Activation Methods

eSIM Profiles 101: SM‑DP+, LPA, EID & Activation Methods

Travelling with an eSIM should be quick and painless, but the jargon around SM‑DP+, LPA and EID can make activation feel more complex than it really is. This guide demystifies the moving parts so you can install, recover or move your eSIM profile with confidence—whether you’re scanning a QR code at the airport or entering details manually on a long‑haul flight. We’ll compare activation methods (QR vs manual), explain where each code lives and what it does, walk through recovery steps if you delete or change phones, and share tips for transferring your plan to a new device. You’ll also find practical troubleshooting for common activation errors and a traveller‑ready checklist to avoid surprises abroad. If you’re heading to the USA, Europe or beyond, we’ve included links to regional plans so you can choose your coverage and get online fast.The building blocks: SM‑DP+, LPA and EID explainedIf you remember only one line from this article, make it this: the LPA on your phone uses your EID to fetch an eSIM profile from an SM‑DP+ server. That’s the whole “smdp+ eid esim” flow in a nutshell.SM‑DP+ (Subscription Manager – Data Preparation)Think of SM‑DP+ as the secure server where your eSIM profile is prepared and hosted.During manual activation, you enter the SM‑DP+ address and an activation code so your phone knows where to download from and which profile to fetch.This is usually embedded inside the QR code; manual entry is the back‑up when you can’t scan.LPA (Local Profile Assistant)The LPA is the software on your device (within iOS/Android) that manages eSIM tasks: downloading, installing, enabling, disabling and deleting profiles.When you scan a QR or enter details, the LPA talks to the SM‑DP+ server to securely download your profile.EID (eUICC Identifier)The EID uniquely identifies your phone’s eSIM chip (like a serial number for the eUICC).Providers sometimes need your EID to push a profile or to re‑enable a download.Where to find it:iPhone: Settings > General > About > EIDPixel/Android: Settings > About phone > Status (or SIMs/eSIM details) > EIDSamsung: Settings > Connections > SIM manager > eSIM > EIDPro tip: Note your EID before you travel. If something goes wrong mid‑journey, support can help faster.Activation methods compared: QR vs manual vs carrier appMost travellers activate by scanning a QR code, but manual entry of SM‑DP+ + activation code is a robust fallback. Some devices and providers also support app‑based activation.Method 1: QR code (fastest for most travellers)What you need: Stable Wi‑Fi (recommended), the printed/digital QR, and your device unlocked.iPhone (iOS 17+): 1. Settings > Mobile Data/Cellular > Add eSIM 2. Tap Use QR Code and scan 3. Follow prompts to label the line and set default for dataAndroid (Pixel): 1. Settings > Network & Internet > SIMs > + Add SIM > Download a SIM instead 2. Scan the QR and confirmSamsung (One UI 6): 1. Settings > Connections > SIM manager > Add eSIM 2. Scan the QR and installPro tips: - Install over Wi‑Fi before you fly to avoid airport Wi‑Fi congestion. - If the camera refuses to scan, increase screen brightness or use manual entry.Method 2: Manual SM‑DP+ + activation codeWhat you need: The SM‑DP+ server address and an activation code (sometimes a confirmation code too).iPhone: 1. Settings > Mobile Data/Cellular > Add eSIM 2. Tap Enter Details Manually 3. Enter SM‑DP+ address and activation code; add confirmation code if requestedAndroid: 1. Go to Add eSIM (as above) 2. Choose Enter activation code or Enter details manually 3. Enter SM‑DP+ address and activation codePro tips: - If you see “No valid SM‑DP+” check for typos, hidden spaces or dashes. - Keep the activation email/PDF offline. Airplane mode plus Wi‑Fi is fine; you don’t need a physical SIM to install an eSIM.Method 3: Carrier or device appSome providers push profiles directly via their app; iPhone also supports “Convert to eSIM” and “eSIM Quick Transfer”.App‑based activations may not work if your device is region‑locked or the app geo‑restricts downloads.When you can’t scan: manual activation that just worksQR codes package the SM‑DP+ address and activation code into one scannable square. If the code is blurry, printed too small, or you’re viewing it on the same device you’re activating, use manual entry.Checklist for reliable manual activation: - Wi‑Fi connected and stable - Correct SM‑DP+ server address (copy/paste carefully) - Activation code exactly as given (case sensitive in some systems) - If asked for a “confirmation code” or “SMDP+ activation code”, that’s the same field as activation code for many providers - Time/date set automatically on your phone (TLS handshakes can fail if your clock is wrong)If you still can’t download, capture a screenshot of the error and share your EID with support. Most providers can trace the server attempt by EID and time stamp.Recovery after deletion or SIM swap: what to expectDeleting a profile or moving phones doesn’t always mean it’s gone for good. Your options depend on the provider’s policy and whether the plan has already been consumed.Common scenarios and recovery steps: - You deleted the eSIM before travelling: - Many plans can be re‑downloaded to the same device. Contact support with your EID and order reference. - You changed phones: - If the provider supports re‑download to a new EID, they’ll usually ask for the new device’s EID. Some plans are single‑use only. - You reset your phone: - iCloud/Google backups do not include the eSIM profile itself. You’ll need to re‑download or transfer it. - Your QR expired: - Ask for fresh SM‑DP+ credentials. Some providers time‑box activation links.Traveller tip: Don’t delete an eSIM until you’re certain you no longer need it (e.g., number transfer complete, data fully used, or plan expired).Moving your eSIM to a new phoneNot all providers support transfers, but when they do, these are the cleanest paths.iPhone to iPhone: eSIM Quick Transfer (best case)Requirements: iOS 16+, both devices nearby, Bluetooth/Wi‑Fi on, same Apple ID often helps.Steps: 1. On the new iPhone: Settings > Mobile Data/Cellular > Add eSIM 2. Tap Transfer from Nearby iPhone 3. Confirm on the old iPhone and follow promptsIf Quick Transfer isn’t offered, use your original QR/SM‑DP+ details or contact support to re‑provision.Android to Android: device tools varyPixel: Settings > Network & Internet > SIMs > Transfer or Add eSIM (if supported)Samsung: Smart Switch can move eSIM on certain models/regions; otherwise use original QR/manual activation.If transfer isn’t available, ask the provider to re‑enable download for your new EID.Cross‑platform (iPhone ↔ Android)Direct transfer isn’t supported. You’ll need re‑provisioning to the new device’s EID with fresh SM‑DP+ credentials.Before you switch phones: - Screenshot your eSIM details (ICCID, plan label) - Note both EIDs (old and new) - Ensure the plan isn’t mid‑use with roaming critical to your tripDual‑SIM travel setup: do it once, do it rightSet your travel eSIM as the Mobile Data line; keep your home SIM for calls/SMS and multi‑factor codes.iPhone: Settings > Mobile Data > Mobile Data > choose your eSIM; turn on Data Roaming for the eSIM only.Android: Settings > Network & Internet/Connections > SIMs/SIM manager > Mobile data > choose eSIM; enable Data roaming for that line.Keep “Allow Mobile Data Switching” off if you want to avoid your phone silently using your home SIM for data.APN: Most eSIMs auto‑configure. If you have no data, enter the APN from your provider’s instructions and restart.Troubleshooting: fast fixes for common activation errors“Unable to complete cellular plan change”Toggle Airplane mode on/off, reboot, and retry on strong Wi‑Fi.Ensure date/time are automatic.“Activation code invalid”Check for stray spaces; try manual entry.Confirm the code hasn’t already been redeemed or expired.Stuck on “Activating”Switch Wi‑Fi networks (captive portals can block downloads).Try another location; some corporate networks block eSIM traffic.Installed but “No Service”Enable Data Roaming for the eSIM line.Set Network Selection to Automatic.Confirm the plan is valid in your country; if you’re in the USA, see regional options like Esim United States or broader Esim North America.Data works, calls/SMS don’tYour plan may be data‑only by design (common for travel eSIMs).Profile disappeared after update/resetIt wasn’t backed up. Contact support with your EID for re‑provisioning options.Picking the right footprint for your tripChoose coverage to match your route: - Single‑country stays: e.g., Esim France, Esim Italy or Esim Spain - Multi‑country tours: Esim Western Europe simplifies roaming across borders - Transatlantic or cross‑border: Esim North America covers USA/Canada/Mexico - See all regions on DestinationsFor teams on the move, centralised purchasing and fleet management are available via For Business. Travel brands and resellers can explore co‑branded or embedded flows in our Partner Hub.Pre‑trip checklist (5 minutes)Confirm your phone is eSIM‑capable and unlockedSave your SM‑DP+ address, activation code and QR offlineNote your EID and order numberInstall on Wi‑Fi before departure; test data onceLabel your lines clearly (e.g., “Home” and “Trip – EU”)Set your eSIM as the data line; enable Data Roaming for that line onlyFAQQ1: What’s the practical difference between EID and ICCID? - EID identifies your device’s eUICC (the chip); ICCID identifies a specific eSIM profile/plan. Support might ask for both, but EID is essential for pushing or recovering a profile.Q2: Do I need to keep the QR code after activation? - Yes. Keep the QR and SM‑DP+ details until the trip is complete. Some providers allow re‑downloads; others treat the code as single‑use.Q3: Can I store multiple eSIMs and switch between them? - Most modern phones store several profiles (e.g., 5–10). You can enable one eSIM data line at a time, then switch in Settings. Delete only when you’re certain you’re done.Q4: Will eSIM activation work without Wi‑Fi? - It can work on mobile data, but Wi‑Fi is more reliable—especially during initial download. Airports and hotels with captive portals can cause issues; a private hotspot is ideal.Q5: My provider asked for my EID to “push” a profile. Is that safe? - Yes—sharing your EID is standard practice for provisioning. It lets the SM‑DP+ server target your device’s eUICC precisely.Q6: How do QR and manual activation differ from a security standpoint? - They’re equivalent. The QR just bundles the SM‑DP+ address and activation code. Manual entry uses the same secure TLS session via the LPA.Next step: choose your coverage and install ahead of your trip.
