What should you buy? Recommendations by trip length

Choose the plan that matches the number of countries and days you’ll actually use, not just the headline data allowance. Here’s how to pick efficiently.

Weekend city break (3–5 days)

Staying put in one country? Choose a single‑country plan:
Esim France for Paris, Lyon, Marseille
Esim Italy for Rome, Milan, Venice
Esim Spain for Barcelona, Madrid, Seville
Crossing a border for a day trip? A regional pass like Esim Western Europe avoids mid‑trip SIM swaps and typically works out cheaper than buying two separate singles.

Tip: For short breaks, a smaller data pack (3–5 GB) is usually enough if you cache maps and use hotel Wi‑Fi.

One to two weeks (7–14 days) with light country‑hopping

Europe: Esim Western Europe covers popular Schengen routes (France‑Belgium‑Netherlands, Spain‑Portugal, Italy‑France‑Switzerland). The Black Friday tier makes the per‑day cost very efficient versus two singles.
North America: Esim North America is ideal if you’re mixing the United States and Canada in one trip. If you’re only in the US, see Esim United States.

Tip: If you expect heavy navigation and social media, aim for 10–15 GB over two weeks. Video calling and hotspotting can double usage quickly.

Three to four weeks, multi‑country road or rail

Europe backpacking or rail pass: Choose a larger Esim Western Europe allowance to avoid mid‑trip top‑ups. The sale’s up to 25% off on regional bundles is built for this scenario.
Canada–US–Mexico loops: Esim North America prevents border‑related service interruptions and multiple APN configurations.

Tip: Check if your route crosses areas with weaker coverage; having multiple partner networks in a regional plan helps.

Work trip or “workation” (2–6 weeks, tethering required)

Consider long‑stay or higher‑GB regional plans, even if you’ll stay in one country. The policy flexibility can be better for hotspot use across devices.
Need multiple lines, pooled data, or centralised invoicing? Set up via For Business. You’ll still benefit from Black Friday pricing during the window.

How to claim your esim black friday deals

Follow this quick workflow to lock in the discount and avoid activation headaches.

Step‑by‑step checkout

Go to Destinations and select your country or region (e.g., Esim Western Europe or Esim North America).
Pick the data allowance and validity that matches your dates.
Add to cart. During the sale window, the discounted price appears automatically. If an on‑site promo code is shown, enter it at checkout.
Complete payment using your preferred method. You’ll receive your eSIM (QR code or activation code) by email and in your account.

Pre‑trip checklist (5 minutes)

Confirm device eSIM compatibility (iPhone XR or later; Google Pixel 3 or later; modern Samsung Galaxy models).
Update your device to the latest OS.
Download or print your eSIM QR code as a backup.
Turn off “Data Roaming” on your physical SIM to avoid bill shock.
Note your travel day; you’ll activate on arrival to maximise validity.

Installing and activating on arrival

iPhone: 1. Settings > Mobile Data > Add eSIM > Use QR code. 2. Label the line (e.g., “Travel eSIM”). 3. Set “Mobile Data” to the eSIM and leave your primary line for calls/WhatsApp if needed. 4. Enable Data Roaming for the eSIM line.
Android (Pixel/Samsung, menus may vary): 1. Settings > Network & Internet > SIMs > + Add eSIM > Use QR code. 2. Select the eSIM for Mobile Data and enable roaming.
APN: Most plans auto‑configure. If not, the APN is supplied in your eSIM email—enter it under Mobile Data Network.
Test: Open a browser to verify. If needed, toggle Airplane Mode off/on once.

Pro tip: Activate over stable Wi‑Fi at the airport or hotel lobby for the smoothest set‑up.

Ways to save more (and avoid common pitfalls)

Match plan to route, not just price. Regional passes can beat single‑country pricing once you add a second border.
Buy before you fly. Sale prices end at 23:59 on Cyber Monday—complete purchase even if you’ll activate later.
Don’t overbuy data. Track usage in your phone settings. If you need more, top up or purchase another eSIM rather than paying for a huge allowance you won’t use.
Keep your home number active for OTPs. Set your physical SIM to “Calls & SMS only” and the eSIM to “Data only.”
Tether wisely. Hotspot is supported on most plans, but streaming in HD will burn data quickly.
For teams, consolidate. Use For Business for shared budgets and central billing; you’ll still capture sale pricing within the window.
Partners and creators: access assets and referral tracking via Partner Hub.

Popular regional picks this season

Esim Western Europe: Ideal for France, Italy, Spain, Portugal, Germany and neighbours—perfect for rail itineraries and festive markets.
Esim North America: Seamless data across the United States, Canada and selected neighbouring territories—good for coast‑to‑coast drives and ski trips.
Esim United States: Strong coverage for major cities and national parks; great value if you’re US‑only.
Esim France, Esim Italy, Esim Spain: Single‑country best‑sellers for winter sun, food trips and art weekends.

Browse all options on Destinations.

FAQ: Black Friday/Cyber Week eSIMs

Can I keep my WhatsApp number while using an eSIM? Yes. Set your primary line for calls/SMS and use the travel eSIM for data. WhatsApp and iMessage typically keep your existing number.
When should I activate my eSIM? Install anytime, but activate (turn on data roaming on the eSIM) on arrival to start the validity clock. This preserves days if your flight is delayed.
Does tethering/hotspot work? On most plans, yes. It depends on the local network policy. If hotspotting matters (for laptop work), choose a plan that explicitly supports it and consider a larger allowance.
What happens if I run out of data mid‑trip? You can purchase an additional pack or a fresh eSIM for the same destination. Activation is near‑instant—keep Wi‑Fi handy for the download.
Can I get an invoice for my company? Absolutely. Use For Business for centralised billing and exports, or contact support after purchase for a VAT/GST invoice where applicable.

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.

APN Settings for eSIM Data (iOS & Android): Find, Edit, Verify

Travelling with an eSIM should be as simple as scanning a QR code and going online. Most of the time it is. When it isn’t, the culprit is often the APN (Access Point Name) — the tiny configuration that tells your device how to reach the mobile data network. This guide shows you exactly where to find APN settings on iOS and Android (including popular vendor skins), what to fill in, and how to verify it’s working with quick tests. We’ll also cover DNS tweaks that can help on the road and a clean troubleshooting flow to get you connected fast.Whether you’re heading to the US, France, Italy, Spain or hopping around Esim Western Europe and Esim North America, correct APN settings are the difference between smooth streaming and a blank browser. Keep your provider’s APN values handy, follow the steps below, and you’ll be back online in minutes. For plan options by country, see our Destinations.What is an APN and why it matters for eSIM dataAPN (Access Point Name) defines the gateway your device uses to access mobile internet.With eSIMs, APN is often auto‑provisioned. Sometimes you must enter it manually.If the APN is missing or wrong, you’ll have signal bars but no data.You’ll typically only need to enter: - APN: a short string (e.g., “internet” or provider‑specific) - Username/Password: usually blank - APN Type: “default,supl” - Protocol: IPv4/IPv6MMS and voice settings are not required for data‑only eSIMs.Before you start: quick checklisteSIM installed and activated on your deviceMobile Data turned onThe eSIM set as the active line for Mobile DataData Roaming on (required when abroad, and sometimes even domestically with certain carriers/MVNOs)Wi‑Fi off while testing (to ensure you’re using mobile data)APN values from your eSIM provider readyTravelling soon? Explore country packs such as Esim United States, Esim France, Esim Italy and Esim Spain.iOS: Find and edit APN settings (iPhone/iPad)Note: On many carriers, iOS hides APN fields because settings are auto‑installed. If you don’t see the menu below, your carrier may not allow manual changes. In that case, re‑installing the eSIM or applying a carrier settings update usually fixes it.Step‑by‑step: 1. Open Settings. 2. Tap Mobile Data (or Cellular). 3. Tap your eSIM line (labelled with the plan name). 4. Tap Mobile Data Network (or Cellular Data Network). - If this menu is missing, APN is likely auto‑configured. Try a carrier settings update: Settings > General > About (wait for an update prompt). 5.

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.Browse regional eSIM options at Destinations or go straight to Esim Western Europe, Esim United States and Esim North America to keep mobile data secure on the move.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 checklistDo these at home on a stable connection with access to your primary number.iMessage/FaceTime (Apple)Update iOS/iPadOS/macOS to the latest version.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).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.Settings > Messages > Send as SMS: Leave On for emergencies, but note SMS isn’t encrypted; watch for green bubbles.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.WhatsAppUpdate WhatsApp.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.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.Settings > Account > Security alerts: - Turn on Security notifications to be alerted when contacts’ security codes change.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.SignalUpdate Signal.Profile > Settings > Account: - Registration lock/PIN: Enable. This prevents someone registering your number on another device without the PIN.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.Safety numbers: - Open each critical contact > Verify safety number (scan QR or compare digits). Re‑verify after device changes.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 hygieneSet 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 safeTravellers 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 riskIf 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.WhatsAppGet 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.SignalOnce 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.iMessageRemove 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 encryptiMessageBest 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.WhatsAppAlways 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.SignaliOS: 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 metadataTurn 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 dataPrefer 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.

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?

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.
