Dual SIM on iPhone with eSIM: Default Line, Data, iMessage/FaceTime

Travel is smoother when your iPhone uses a local data plan while your home number stays reachable. That’s exactly what Dual SIM with eSIM enables. In this guide we’ll show you, step by step, how to add and label lines, choose your default for calls and SMS, set the correct data line, and decide which number powers iMessage and FaceTime. We’ll also cover roaming-safe presets so you land, switch on, and avoid bill shock. Whether you’re heading to the US, Europe or further afield, a few minutes of set-up makes the difference between seamless connectivity and expensive mistakes. If you need an eSIM first, browse country and regional plans on our Destinations page, including regional bundles like Esim Western Europe and Esim North America, or country options such as Esim United States, Esim France, Esim Italy, and Esim Spain.

What “Dual SIM with eSIM” means on iPhone

  • You can have two mobile plans on one iPhone: typically your physical SIM (home number) plus an eSIM (travel data), or two eSIMs on newer models.
  • You choose which line handles voice and SMS by default.
  • You pick a single data line at any time, with optional “Allow Mobile Data Switching” to keep data alive for calls on the other line.
  • iMessage and FaceTime can be tied to either number (or your Apple ID), and you can switch per-contact when needed.

This guide focuses on practical, traveller-first settings to keep your home number reachable while your travel eSIM handles data securely and affordably.

Check your iPhone supports Dual SIM with eSIM

Most recent iPhones support Dual SIM. Quick checkpoints:

  • iPhone XS/XR and later: Dual SIM (one physical SIM + one eSIM).
  • iPhone 13 and later: can support two active eSIMs simultaneously (no physical card required).
  • US-model iPhone 14 and newer: eSIM-only (no physical SIM slot).

To confirm on your device: 1. Go to Settings > General > About. 2. Look for “Digital SIM” or “eSIM” entries. If you see IMEI entries for two eSIMs, your phone supports dual eSIM. 3. Ensure you’re on the latest iOS for best Dual SIM features.

Step 1: Add your travel eSIM and label your lines

Before you fly, install and label your eSIM so switching is painless on arrival.

  1. Purchase the right plan for your trip: - North America: Esim North America - United States: Esim United States - Western Europe: Esim Western Europe - Popular countries: Esim France, Esim Italy, Esim Spain - Explore all options: Destinations
  2. Install the eSIM: - Settings > Mobile Data (Cellular) > Add eSIM. Follow the on‑screen steps to scan your QR code or use the activation code. - If offered, “Convert to eSIM” can move your physical SIM to eSIM on supported devices.
  3. Label each line clearly: - iOS prompts you to label the plans. Choose intuitive labels like “Home” and “Travel”. - You can rename later: Settings > Mobile Data > tap a plan > Label.

Pro tips: - Label accuracy is crucial; it’s how you’ll pick the right line in call/message screens. - Install eSIM while you still have good Wi‑Fi and time to test.

Step 2: Choose your default line for calls and SMS

This controls which number your iPhone uses when you tap a number or send an SMS from scratch.

  1. Go to Settings > Mobile Data > Default Voice Line.
  2. Pick “Home” (your primary) if you want all ordinary calls/SMS to continue from your usual number.
  3. If you prefer to make outbound calls from your travel number (e.g., local business calls abroad), choose “Travel”.

Per-contact preference: - Open the Contacts app > select a contact > tap “Preferred Line” (or “Preferred Cellular Plan”) > choose Home or Travel. - iPhone learns your behaviour and can automatically use the last line you used for that contact.

Pro tip: - Keep Default Voice Line = Home, then set exceptions (like hotels/restaurants) to Travel so you appear local.

Step 3: Set your mobile data line and Roaming

This is the big one for bill safety: make the eSIM your data source and block roaming on your home line.

  1. Settings > Mobile Data > Mobile Data > select “Travel”.
  2. Tap your Home line > toggle Data Roaming OFF.
  3. Tap your Travel line > toggle Data Roaming ON (if you’re abroad) so data works when you land.
  4. Optional: under Mobile Data, enable “Allow Mobile Data Switching”. This lets iPhone temporarily use the data line for ongoing voice calls on the other line. If you want strict control (no surprises), keep this OFF.

When to disable your Home line entirely: - If your carrier charges for incoming roaming calls, you may prefer to disable the Home line: Settings > Mobile Data > tap Home > Turn On This Line = OFF. - If you still need OTP texts or critical calls, leave the Home line ON but keep Data Roaming OFF (you can still receive SMS over the cellular network; check your carrier’s policies for any charges).

Pro tips: - Test data before you fly: switch Mobile Data to Travel, toggle Data Roaming ON, then back to Home until you depart. - If your Travel plan includes Wi‑Fi calling, consider making calls over apps (WhatsApp, FaceTime, Teams) to avoid local call charges.

Step 4: Set iMessage and FaceTime to the right number

You can attach iMessage/FaceTime to your travel number or keep them linked to your home number while using the travel eSIM for data.

iMessage: 1. Settings > Messages > iMessage = ON. 2. Tap Send & Receive. 3. Tick the phone numbers and/or Apple ID you want active. 4. Under “Start New Conversations From”, choose the number you want by default (Home or Travel).

FaceTime: 1. Settings > FaceTime > FaceTime = ON. 2. Tick the addresses/numbers to receive calls at. 3. Set “Caller ID” (or similar option) to the number you want people to see when you call.

Switch the line per conversation: - In Messages, open a conversation > tap the contact name/photo at the top > change the line if the option appears (or start a new message and tap the line label above the keyboard to choose Home/Travel before sending).

Pro tips: - For continuity with family and friends, keep iMessage/FaceTime on your Home number and use the Travel number only for local contacts. - If verification codes arrive via iMessage instead of SMS, they’ll still work over your Travel data because iMessage uses the internet.

Traveller presets: fast, safe switching

iOS doesn’t have one‑tap “profiles”, but you can mimic them with a simple routine.

Before you fly (10‑minute checklist): - Install and label your eSIM: “Travel”. - Settings > Mobile Data: - Mobile Data = Home (for now). - Home line > Data Roaming = OFF. - Travel line > Data Roaming = ON. - Messages > Send & Receive: - Choose “Start New Conversations From” = Home (or Travel if you want a local sender ID). - FaceTime > Caller ID = preferred number. - Save a few key contacts with Preferred Line = Travel (hotel, taxi, local colleagues).

On the plane/at the gate: - Settings > Mobile Data > Mobile Data = Travel. - Optional: Allow Mobile Data Switching = OFF for strict control.

On arrival: - Toggle Airplane Mode OFF; wait 1–2 minutes for the Travel eSIM to register. - Confirm data works (open a lightweight website). - Make a quick test call/iMessage.

During your stay: - Keep Home line ON with Data Roaming OFF to receive SMS when needed. - For local calls, set Preferred Line = Travel per contact or temporarily switch the Default Voice Line.

Heading home: - Switch Mobile Data back to Home. - Turn off the Travel line if you won’t use it until your next trip, or leave it installed for future travel.

Troubleshooting: quick fixes that work

No data on the Travel eSIM: - Check Settings > Mobile Data > Mobile Data = Travel. - Settings > Mobile Data > tap Travel > Data Roaming = ON. - Restart iPhone; toggle Airplane Mode for 10 seconds. - Settings > General > About: if prompted for a Carrier Settings Update, accept. - If your plan requires a specific APN, it should auto‑configure with eSIM; if not provided, contact support.

Calls/SMS using the wrong number: - Settings > Mobile Data > Default Voice Line = intended line. - For specific contacts, set Preferred Line. - In the Messages conversation, change the line before sending.

iMessage/FaceTime not activating: - Ensure you have data on the active line and can receive SMS on at least one line. - Toggle iMessage/FaceTime OFF and back ON. - Sign out/in of Apple ID in Messages/FaceTime settings as a last resort.

Can’t see “Allow Mobile Data Switching”: - It shows only when both lines are active and one is selected for Mobile Data.

Missing the option to assign “Preferred Line”: - Make sure both lines are turned ON (Settings > Mobile Data > tap each plan).

Picking the right eSIM for your route

For teams and frequent travellers: - Centralise budgets and provisioning via For Business. - Travel agencies, IT resellers and affiliates can explore our partner tools at the Partner Hub.

Pro tips for power users

  • Dual SIM iPhone eSIM pairing: on iPhone 13 and newer, you can keep two eSIMs active—useful if your “home” number is also an eSIM.
  • Visual labelling: add emojis to line labels (e.g., “Home 🏠”, “Travel ✈️”) to avoid mistakes when switching lines in Messages or Phone.
  • Battery and coverage: if coverage is weak on one line, disabling that line can improve standby time.
  • Maps and ride‑hailing: test these apps on the Travel data line before leaving the airport to confirm routing and SMS verification work.
  • Keep it simple: Default Voice Line = Home, Mobile Data = Travel is the safest starting point for most travellers.

FAQ

1) Can I keep my home SIM for calls/SMS but use the eSIM for data? - Yes. Set Default Voice Line = Home. Set Mobile Data = Travel. Turn Data Roaming OFF on Home. You can still receive SMS on Home while using data on Travel.

2) Will I get roaming charges on my home line if it’s on? - Data roaming is prevented if you turn Data Roaming OFF on the Home line. Voice/SMS charges depend on your carrier and whether you answer/receive calls or send texts while abroad. For maximum control, you can turn the Home line OFF entirely.

3) Can iMessage/FaceTime use my home number while data comes from the Travel eSIM? - Yes. iMessage/FaceTime work over the active data connection, regardless of which number you choose in Send & Receive/Caller ID. Pick “Start New Conversations From” = Home to keep continuity.

4) How do I switch the sending line in a specific message thread? - Open the conversation, tap the header (contact name/photo), and choose the line, or start a new message, then tap the line label above the keyboard to switch before sending.

5) Why don’t I see both lines at once? - Ensure your iPhone supports Dual SIM and both lines are turned ON: Settings > Mobile Data > tap each plan > Turn On This Line. Older models may support only one eSIM plus one physical SIM, while newer models support two eSIMs.

6) Can I keep two eSIMs active, no physical SIM? - On iPhone 13 and newer, yes—two active eSIMs are supported. US-model iPhone 14+ are eSIM-only devices and handle multiple eSIMs easily.

Next step: Choose the right travel plan for your route on Destinations, then follow the steps above to set Mobile Data = Travel and Default Voice Line = Home before you fly.

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.

Most recent iPhones (XS or newer) and many flagship/mid‑range Androids support eSIM. Each traveller needs an unlocked device.2) Can I mix iOS and Android in one pack?Yes. The shared pool and admin controls are platform‑agnostic.3) Can I add a line after purchase?Yes, up to a maximum of five lines per pack. New lines inherit the pack’s remaining validity and shared pool.4) What happens if we run out of data?Data stops when the shared pool reaches zero. Add a top‑up (e.g., +10 GB) in a few taps; it becomes available instantly.5) Do unused GB roll over or can I extend validity?Unused GB do not roll over. To extend your stay, either add another pack or schedule a second pack to start when the first ends.6) Will WhatsApp and iMessage keep my number?Yes. Your phone number stays tied to your primary SIM; the eSIM is for data. Apps like WhatsApp and iMessage continue to use your existing number.The small, useful printSpeeds depend on network conditions, device, and location. 5G is available in select areas.Hotspot is supported on most networks but may vary; you can disable it per line in the admin controls.Per-line caps help manage usage but won’t limit data consumed while a device is offline from reporting; allow a small buffer if you need a strict cap.Taxes may apply in some regions. Prices above show promotional examples and can change during the offer window.Next step: choose your region and build your Family Pack 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.
