Dual SIM with eSIM: Two Numbers on One Phone (Calls, OTPs, Data)

Staying reachable without burning money on roaming is the modern traveller’s headache. Dual SIM with eSIM solves it: keep your main number active for calls and OTPs, and add a low-cost local or regional data plan on the same phone. No SIM swapping. No missed texts from your bank. In this guide, we explain how dual SIM with eSIM works, how calls/SMS/data behave, and how to set it up on iPhone and Android. We also cover common use cases like work/personal separation and travel/local pairing, plus how WhatsApp and other apps handle two numbers. If you’re planning a trip, browse country and regional options via Destinations or pick ready-made bundles such as Esim Western Europe or Esim North America. For the US or single-country trips, see Esim United States, Esim France, Esim Italy and Esim Spain.

What is dual SIM with eSIM?

Dual SIM means your phone can maintain two mobile lines at once. One or both can be eSIMs (digital SIM profiles). Typical setups: - Physical SIM + eSIM active together. - Two eSIMs active (on many newer devices). - Multiple eSIM profiles stored, with up to two active at a time (device-dependent).

On dual SIM dual standby (DSDS) phones, both lines are “on” for calls and texts when idle. You set a default line for data, calls and messages, and you can switch defaults at any time.

Device support varies. Recent iPhones and most mid/high-end Android phones support dual SIM with eSIM, but some models allow only one eSIM active at a time or restrict 5G/VoLTE on the secondary line. Check your device’s specs before you travel.

Why use dual SIM eSIM? Practical use cases

Work and personal separation

  • Keep your personal number private while making and receiving work calls on a second line.
  • Set the default for outgoing calls to your work line during office hours and flip it back to personal later.
  • Mute one line at set times to reduce interruptions without missing urgent personal calls.

Travel: keep your home number for OTPs, add local data

Coverage and cost optimisation

  • Use the line with stronger coverage for data in fringe areas.
  • Keep a cheap voice/SMS plan on one line and a high-data plan on the other.
  • Switch defaults on the fly when you cross borders or move between networks.

Teams, events and short-term projects

  • Provision temporary eSIM lines for contractors, events or field staff without shipping plastic SIMs.
  • Centrally manage usage and budgets; see For Business.
  • Partners and resellers can streamline deployments via the Partner Hub.

How calls, SMS, data, OTPs and apps behave

Understanding how two lines interact avoids surprises.

  • Calls in standby: Both lines can receive calls when idle. When you place or receive a call on one line, the other may go to voicemail or show as unreachable unless your device/network supports features like call waiting across lines or Wi‑Fi Calling. Behaviour varies by carrier and phone.
  • Default for voice/SMS: You choose a default line for outgoing calls and texts, but you can select the other line per contact or per call.
  • Mobile data: Only one line provides mobile data at a time. You set this in settings. Some phones support “allow mobile data switching”, automatically using the other line if the selected data line has weak signal.
  • SMS-based OTPs: OTP texts arrive on the line tied to that number as long as that line is enabled and has signal. Data does not need to be enabled on that line. If you’re abroad, receiving OTPs may incur roaming SMS charges on your home line—turn off data roaming but keep SMS/calls enabled to control costs.
  • iMessage/FaceTime (iPhone): You can enable iMessage/FaceTime for one or both numbers and choose which to use by default.
  • WhatsApp and similar apps:
  • The standard WhatsApp app supports one number per device. Data can come from either line.
  • To run two WhatsApp accounts on one phone, use WhatsApp + WhatsApp Business (iOS/Android) or OEM dual-app features (on some Android devices).
  • Your WhatsApp number does not change just because your data comes from your travel eSIM.

Set-up: dual SIM with eSIM

iPhone step-by-step

  1. Obtain your eSIM details: QR code or activation code from your provider.
  2. On iPhone, go to Settings > Mobile Data > Add eSIM (or “Add Data Plan”).
  3. Scan the QR code or enter details. Wait for activation.
  4. Label your lines (e.g., “Personal” and “Travel”). Clear labels prevent mistakes.
  5. Choose defaults: - Default Line for Calls and SMS. - iMessage & FaceTime line. - Mobile Data line (set to your travel/local eSIM when abroad).
  6. Toggle “Data Roaming”: - Turn off for your home line while travelling. - Turn on for your travel eSIM, if required.
  7. Optional: Enable “Allow Mobile Data Switching” if you want automatic fallback.
  8. Test: Place a call from each line, send yourself an SMS from another phone, and load a webpage to confirm the data line.

Pro tips for iPhone: - You can store multiple eSIMs and swap which are active. Many newer iPhones support two active eSIMs. - Backups don’t include eSIMs. Keep your activation details safe; some carriers limit re-downloads. - For Wi‑Fi Calling, enable it separately per line (Settings > Phone > Wi‑Fi Calling).

Android step-by-step (Pixel/Samsung and similar)

  1. Get your eSIM QR/activation details from your provider.
  2. Open Settings > Network & Internet (or Connections) > SIMs > Add eSIM.
  3. Scan the QR code or enter details. Wait for activation.
  4. Name each SIM (e.g., “Work” and “Data”).
  5. Set preferences: - Preferred SIM for Calls. - Preferred SIM for SMS. - Preferred SIM for Mobile Data (set to the travel/local eSIM).
  6. Roaming: - Disable data roaming on your home line. - Enable on your travel eSIM if needed.
  7. Optional: Enable “Switch data automatically” or similar to allow fallback.
  8. Test calls, SMS, and data on both lines.

Pro tips for Android: - Some phones let you duplicate apps (Dual Messenger/App Twin) to run two WhatsApp accounts. Alternatively, use WhatsApp + WhatsApp Business. - Not all Android models support two eSIMs active simultaneously. If yours doesn’t, use one physical SIM + one eSIM, or swap active eSIM profiles as needed. - VoLTE/5G availability can differ per SIM slot/line; check your device and carriers.

Travel checklist: avoid bill shock and stay reachable

Before you fly: - Install and activate your travel eSIM over Wi‑Fi at home. - Label lines clearly and set the travel eSIM as the Mobile Data line. - Turn off Data Roaming on your home line; leave Calls and SMS on if you need OTPs. - Enable Wi‑Fi Calling for your home line if supported, to improve reachability without roaming data. - Check voicemail and call forwarding settings for both lines. - Tell your bank you’re travelling; ensure OTPs can arrive via SMS or app. - Save carrier support contacts and your eSIM activation details offline.

On arrival: - Confirm the travel eSIM connects and data works. - Place a brief test call from each line and send a test SMS. - Keep an eye on status bar icons to ensure you’re not accidentally using data on the home line.

Pro tips and common gotchas

  • Keep eSIM credentials safe: Many providers allow limited re-installs. Don’t delete an active eSIM while abroad unless you’re certain you can re-download it.
  • One data line at a time: Even with two active lines, only one provides mobile data. Choose carefully for maps, ride-hailing and tethering.
  • Call collisions: During a call on one line, the other may be unreachable on some networks. If that’s critical, enable Wi‑Fi Calling and test how your phone behaves.
  • Battery impact: Two active lines can use more battery. Mitigate by disabling 5G on the non-data line, reducing background activity, and using Wi‑Fi where possible.
  • Apps tied to a number: Services like WhatsApp, Signal and Telegram can be re-registered to another number, but you may lose message history or access. Decide which number you want long-term before switching.
  • Region-savvy plans: Multi-country eSIMs like Esim Western Europe simplify border crossings; US/Canada/Mexico travellers can look at Esim North America. Compare options by country on Destinations.

Regional picks for travellers

FAQs

  • Can I use both numbers at the same time?
  • Yes, both lines are on standby for calls and texts. Only one line provides mobile data at a time. If you’re on a call on one line, the other may be temporarily unreachable depending on device/network features.
  • Will OTP texts arrive while my data is on the other eSIM?
  • Yes. OTPs arrive on the line associated with that number as long as that line is enabled and has signal. Data does not need to be on for SMS. Roaming SMS fees may apply if you’re abroad on your home line.
  • Can I use WhatsApp with two numbers on one phone?
  • The standard app supports one number. To run two accounts, use WhatsApp + WhatsApp Business (works on iOS and Android) or an OEM dual-app feature on some Android phones. Your data can come from either line regardless of the WhatsApp number.
  • How do I avoid roaming charges on my home SIM?
  • Turn off Data Roaming for the home line. Keep Calls and SMS on if you need to receive OTPs or critical calls. Set your travel eSIM as the Mobile Data line. Consider Wi‑Fi Calling to improve reachability without data roaming.
  • Does dual SIM affect battery life?
  • Slightly, because the phone maintains two network registrations. Reduce impact by disabling 5G on the non-data line, using Wi‑Fi, and turning off the secondary line when not needed.
  • What if my phone supports only one eSIM active at a time?
  • Use one physical SIM plus one eSIM, or store multiple eSIM profiles and switch which is active as required. Check your device manual for limits on active lines and 5G support.

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.

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.

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.
