Business Travel Connectivity Playbook (2025): Best eSIMs, Hotspot & VPN

29 Oct 2025

Planning trips is hard enough without worrying about connectivity. This playbook gives travelling professionals and travel managers a clear, practical path to fast, secure mobile data on every trip. You’ll learn how to choose the best eSIM for business travel by itinerary (single-country vs regional), how to keep laptops online via tethering without draining your phone, and how to lock down security with a VPN—all while keeping expenses tidy. We also cover multi‑network reliability, so your phone latches onto the strongest local carrier, not just the first one it finds. Real-world tips, checklists, and quick fixes are included to reduce day-one friction at the airport or hotel. Whether you’re hopping between New York, Paris, and Barcelona or rotating across US cities, this guide shows you exactly which plans to pick, how to activate them in minutes, and how to avoid surprise costs—all in plain English, traveller-first.

Why eSIM beats roaming for business travel in 2025

Predictable costs: Local eSIM data often costs a fraction of traditional roaming day passes. Regional eSIMs unlock even better value per GB for multi‑stop itineraries.
Multi‑network reliability: Quality eSIMs can access multiple local carrier networks, letting you manually switch to the strongest signal if reception drops.
Instant, remote setup: Add an eSIM by scanning a QR code—no physical SIM swap. Managers can provision profiles centrally and ship nothing.
Dual-line convenience: Keep your primary number active for calls/SMS while running data over the eSIM.
Security control: Pair with a corporate VPN and MDM policies for consistent protection across regions.

How to choose the best esim for business travel

Use this quick decision framework before every trip:

1) Where are you going? - One country, one city: Choose a country eSIM. Examples: Esim United States, Esim France, Esim Italy, Esim Spain. - Several neighbouring countries: Pick a regional eSIM for simpler management and lower per‑GB cost. For Europe, see Esim Western Europe. For transborder North American circuits, see Esim North America. - Not sure about coverage? Browse by country or region in Destinations.

2) How long and how heavy is your usage? - Light (email, chat, maps): 3–5 GB per week. - Standard (video calls, cloud docs): 8–15 GB per week. - Heavy (frequent HD calls, large uploads): 20–40 GB per week.

3) Performance needs - 5G vs 4G LTE: If you present or transfer large files, 5G helps—especially in urban centres. If coverage is spotty, 4G LTE with good multi‑network access can be more stable. - Hotspot use: Confirm hotspot is allowed; most data eSIMs support tethering.

4) Organisation requirements - Central billing, spend caps, and provisioning? Use For Business. - Partnerships/resellers? Explore the Simology Partner Hub.

Frequent-flyer plan picks (by itinerary)

North America routes (US/Canada/Mexico)

Best fit: Esim North America
Why: Seamless cross-border data, single profile, fewer mid‑trip switches, strong networks in major business hubs.
When to go single-country: If you’re US‑only for the week, Esim United States can be more cost‑efficient at lower data volumes.

Western Europe multi‑stop (e.g., Paris–Milan–Barcelona)

Best fit: Esim Western Europe
Why: Pan‑country coverage under one plan reduces admin, avoids mid‑trip downtime, and often delivers better value per GB across multiple borders.
Single-country alternatives:
France: Esim France
Italy: Esim Italy
Spain: Esim Spain

Transatlantic shuttles (US–EU return trips)

Best fit: Pair the region you spend the most data in (e.g., Esim North America) with a European regional plan like Esim Western Europe for the EU leg. Keep both installed and toggle the active data line as you land.

Pro tips - If your schedule changes often, choose plans that allow top‑ups rather than locked bundles. - For quarterly repeats, keep regional eSIMs installed; many remain dormant without charges until you add data again.

Pre‑trip setup checklist (10 minutes)

Confirm device compatibility and unlock status.
Update iOS/Android to the latest version.
Purchase the right plan(s) by itinerary: country vs regional. Use Destinations to double‑check coverage.
Add the eSIM: scan QR or install via app. Label it by region (e.g., “EU Data”).
Set the eSIM as your default data line; keep your primary SIM for calls/SMS.
Turn off data roaming on your primary SIM to avoid bill shock.
Check APN settings are auto‑configured; note them if you need to enter manually.
Test before departure: briefly enable the eSIM to confirm registration (where supported).
Enable hotspot and verify your laptop connects; set a strong password.
Install/verify your corporate VPN app; enable kill switch and auto‑connect.
Configure OS data-saver modes and disable heavy cloud backups on mobile data.
Set data usage alerts (e.g., at 80% of your allowance).
For teams: set budgets, assign profiles, and centralise receipts via For Business.

On‑arrival steps (5 minutes)

1) Turn off airplane mode; ensure your primary SIM’s data roaming remains off. 2) Enable the eSIM data line; allow roaming on the eSIM. 3) If data doesn’t start, manually select a different local network (multi‑network plans allow this). 4) Verify APN settings match the eSIM’s instructions. 5) Run a quick speed test. If speeds are poor, try another partner network. 6) Connect your laptop via hotspot (5 GHz band if available) and launch your VPN. 7) Set a reminder to check usage mid‑trip and top up if needed.

Laptop tethering and VPN best practices

Hotspot without headaches - Prefer 5 GHz hotspot for faster, more stable connections; fall back to 2.4 GHz in crowded RF environments. - Use a unique SSID and a strong WPA2/WPA3 password; avoid “Auto Join” on shared devices. - Limit connected devices to those you need; disconnect tablets after meetings. - Keep your phone on power when tethering; hotspots drain batteries quickly. - For all‑day workshops or teams, consider splitting between two phones or using a dedicated travel router fed by your phone via USB tethering.

VPN essentials for travellers - Always-on VPN: Enable auto‑connect on untrusted networks (hotel, airport). - Protocols: WireGuard or IKEv2 are reliable and efficient on mobile networks. - Kill switch: Prevents data leaking if the VPN drops. - Split tunnelling: Route corporate apps via VPN while keeping video calls local if policy permits—reduces latency. - Beat captive portals: Connect and pass the hotel’s login page before enabling the VPN, or use your hotspot to bypass captive portals for sensitive work.

Reliability: multi‑network and smart fallback

Pick eSIMs with access to multiple carriers in‑country. If one network degrades in a conference venue, switch to another.
Keep two profiles installed for high‑stakes trips (e.g., a country eSIM plus a regional backup). Toggle as needed.
Use Destinations to check country‑specific notes on networks, 5G availability, and any APN nuances.
Store QR codes or install instructions offline in your password manager in case hotel Wi‑Fi is down.

Cost control and expense-friendly tips

Right-size your data - Week in one country: choose a country plan sized to your workload. - Multi‑country fortnight: regional plan with a bigger allowance usually wins on cost per GB. - Returning often? Keep the eSIM profile and top up data for each trip—no shipping, no activation lag.

Reduce data waste - Disable automatic cloud photo/video backups on mobile data. - Download decks, maps, and media offline before flights. - Turn off auto‑updates; schedule them for hotel Wi‑Fi. - In conferencing apps, cap video at 720p when mobile.

Make finance happy - Centralise purchasing, budgets, and invoices via For Business. - Standardise plan types by route (e.g., “EU 10 GB” for 3‑day trips) to simplify approvals. - For agencies and MSPs handling multiple clients, streamline provisioning and commercial terms through the Partner Hub.

Security and compliance in the field

BYOD vs corporate: Apply MDM profiles to enforce VPN, PIN/biometric, and remote wipe.
SIM protection: Use device PIN and biometric; enable Find My/Find Device.
App hygiene: Remove unneeded apps with background data access before travel.
Public Wi‑Fi caution: Prefer your own hotspot; if you must use hotel Wi‑Fi, run your VPN with a kill switch.

Quick troubleshooting

No data on arrival? - Ensure the eSIM is the active data line and data roaming is on (for the eSIM only). - Toggle airplane mode off/on; then try manual network selection. - Check APN; enter the one provided if not auto-filled. - Restart the device. Test again. Try switching to another partner network.

Slow speeds? - Move away from congested areas (conference halls can be saturated). - Switch from 5G to 4G LTE or vice versa; sometimes LTE is more consistent indoors. - Try another available network if your plan supports multi‑network access.

Hotspot won’t work? - Confirm the plan allows tethering; re‑set the hotspot password; try 2.4 GHz if older laptops struggle with 5 GHz. - USB tether for maximum stability and to charge simultaneously.

FAQ

1) What’s the best esim for business travel if I visit several countries in a week? - Choose a regional plan for simplicity and value. For Europe, see Esim Western Europe. For cross‑border trips in the US/Canada/Mexico corridor, use Esim North America.

2) Can I use my eSIM for laptop tethering? - In most cases, yes. Hotspot/tethering is widely supported on data eSIMs. Enable personal hotspot on your phone, set a strong password, and keep the device charged.

3) How much data do I need for a typical week of meetings? - Light workflows: 3–5 GB. Moderate with daily calls: 8–15 GB. Heavy video conferencing and large file syncs: 20–40 GB. If in doubt, pick a slightly larger plan and set usage alerts.

4) Will I keep my usual phone number for calls and WhatsApp? - Yes. Keep your primary SIM active for calls/SMS/WhatsApp identity, and set the eSIM as your data line. Most travel eSIMs are data‑only.

5) Do eSIMs support multiple networks and 5G? - Many do. Multi‑network access lets you switch carriers for better coverage. 5G is available in most major cities, with 4G LTE fallback elsewhere. Check specifics by country via 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.
