iPad eSIM Setup (Wi‑Fi + Cellular): Supported Models & Steps

30 Oct 2025

If you travel with an iPad, an eSIM is the cleanest way to get online without hunting for physical SIMs. This guide covers exactly which iPads support eSIM, how to install a travel eSIM step‑by‑step, and how to configure data, roaming and Personal Hotspot so your other devices can share the connection. We’ve written this with travellers in mind: fast, reliable setup, minimal faff.

A quick heads-up: eSIM works only on Wi‑Fi + Cellular iPad models, not Wi‑Fi‑only versions. Availability of eSIM can also vary by country or region (for example, eSIM on iPad is not offered in mainland China). Below you’ll find a simple model matrix, essential pre‑checks, and three install methods (QR code, activation code, and link). We’ll also share practical hotspot tips, how to switch or remove plans, and troubleshooting steps if something doesn’t behave.

When you’re ready to pick a plan, explore region and country options on our global Destinations, including popular picks such as Esim United States, Esim France, Esim Italy, Esim Spain, Esim Western Europe and Esim North America.

Quick check: does your iPad support eSIM?

Only Wi‑Fi + Cellular models support any mobile plan (physical SIM or eSIM).
eSIM support starts from specific generations (see lists below).
Mainland China: iPad models with eSIM are not offered; availability in Hong Kong and Macao depends on local carriers.
To confirm your model: Settings > General > About > Model Name and Model Number.

iPad models that support eSIM (Wi‑Fi + Cellular)

If your iPad is one of the following, it supports eSIM in most regions outside mainland China:

iPad Pro
12.9‑inch (3rd generation and later: 2018, 2020, 2021, 2022 and newer)
11‑inch (1st generation and later: 2018, 2020, 2021, 2022 and newer)

Tip: Even on eSIM‑capable iPads, there may also be a physical nano‑SIM tray. You can use either a physical SIM or eSIM (one active plan at a time).

Models without eSIM (Apple SIM or physical SIM only)

These iPads do not support eSIM. Some include Apple SIM (removable or embedded), which Apple discontinued for new activations. You’ll need a physical SIM if you’re using these models.

iPad Pro 12.9‑inch (1st and 2nd gen: 2015, 2017)
iPad Pro 10.5‑inch (2017)
iPad Pro 9.7‑inch (2016)

iPad (5th gen, 2017; 6th gen, 2018)
iPad mini 3 (2014), iPad mini 4 (2015)

Note on Apple SIM: Apple ended remote provisioning for Apple SIM in 2022. If you relied on Apple SIM for travel data, upgrade to an eSIM‑capable iPad or use a physical SIM from a local carrier.

What you need before you start

A Wi‑Fi + Cellular iPad that supports eSIM (see lists above)
A stable Wi‑Fi connection for activation
iPadOS updated (Settings > General > Software Update)
An unlocked device (or a plan compatible with your iPad’s lock status)
Your eSIM details from your provider:
A QR code to scan; or
An activation code (SM‑DP+ address + Activation Code); or
An install link you can open on the iPad
Enough battery or a charger nearby

Pro tip: Travelling to multiple countries? Consider regional plans like Esim Western Europe or Esim North America so you don’t have to swap or re‑install between borders.

iPad eSIM setup: three easy methods

On iPad, the menu is “Mobile Data” (instead of “Cellular” on iPhone). Depending on iPadOS version, wording may be “Add eSIM” or “Add Data Plan”.

Method 1: Scan a QR code (fastest)

Connect the iPad to Wi‑Fi.
Go to Settings > Mobile Data.
Tap Add eSIM or Add Data Plan.
Choose Use QR Code. Aim the camera at the QR code.
When the plan appears, tap Continue, then Add Data Plan.
If prompted, label the plan (e.g., “Trip Europe”).
Let the activation complete, then follow any on‑screen prompts.

If the camera can’t read the code, ensure good lighting and a steady hand. If it still fails, use Method 2 with the manual SM‑DP+ details.

Method 2: Install via activation code (SM‑DP+ address)

Connect to Wi‑Fi and open Settings > Mobile Data.
Tap Add eSIM or Add Data Plan.
Select Enter Details Manually.
Enter the SM‑DP+ Address and Activation Code exactly as provided. Leave Confirmation Code blank unless your provider gave one.
Tap Next and wait for the plan to download.
Add the plan and assign a label when prompted.

Tip: These fields are case‑sensitive. Copy/paste if possible to avoid typos.

Method 3: Install via link

With Wi‑Fi on, open the install link provided by your eSIM seller directly on the iPad.
Tap Allow when iPad prompts to add a mobile data plan.
Follow the on‑screen steps to add and label the plan.

If you received the link on another device, email it to yourself or open it in a synced note on the iPad.

Configure data, roaming and Personal Hotspot

Once your plan is installed, configure it for travel.

Set your data plan and enable roaming

Settings > Mobile Data.
Under Mobile Data, ensure your new plan is selected for data.
Tap Mobile Data Options > Data Roaming and turn it on if you’re using the plan outside its home country.
If your provider gave APN settings, tap Mobile Data Network and enter the APN, Username and Password as instructed. Most travel eSIMs auto‑configure.

Pro tip: If you also have a physical SIM inserted, choose which plan provides data to avoid accidental roaming fees on the other plan.

Turn on Personal Hotspot

Settings > Personal Hotspot (or Settings > Mobile Data > Personal Hotspot).
Toggle Allow Others to Join.
Set a strong Wi‑Fi password.
Optional: turn on Maximise Compatibility (makes the hotspot more compatible with older devices by using 2.4 GHz; slightly reduces top speeds).

Hotspot travel tips: - Keep the iPad charging when tethering for long periods. - Place the iPad near a window for better signal. - If speeds drop, toggle Airplane Mode off/on or briefly turn the hotspot off/on to refresh the session. - Some plans restrict tethering; check your plan terms if the hotspot toggle is missing or won’t stay on.

Switching, pausing or removing eSIM plans

Temporarily turn a plan off: Settings > Mobile Data > tap the plan > turn off Turn On This Line.
Switch data between plans: Settings > Mobile Data > Mobile Data (select the plan for data).
Rename a plan: Settings > Mobile Data > tap the plan label > Change Label.
Remove a plan: Settings > Mobile Data > tap the plan > Remove Data Plan. Removing deletes the eSIM profile from your iPad. Keep your QR/activation details if you might need to reinstall (reinstallability depends on your provider’s policy).

Storage: iPad can store multiple eSIM profiles, but only one can provide data at a time.

Troubleshooting and pro tips

If something isn’t working, run through these checks:

“Add eSIM” is missing
Ensure you’re on a Wi‑Fi + Cellular model that supports eSIM.
Update iPadOS and restart.
If your iPad was bought in a region that restricts eSIM, the option may be unavailable.
QR code won’t scan
Clean the camera lens; brighten the screen showing the code.
Zoom the code on another device or print it larger.
Use manual entry via SM‑DP+ and Activation Code.
“Activation code invalid” or “Can’t add plan”
Confirm the SM‑DP+ address and Activation Code are entered exactly.
Check that your plan hasn’t already been installed on another device.
Try again on a stronger Wi‑Fi network.
“No Service” after install
Settings > Mobile Data > ensure the new plan is On and selected for data.
Turn on Data Roaming if abroad.
Check Mobile Data Network for custom APN details (if provided).
Update Carrier Settings: Settings > General > About (wait for any prompt).
Toggle Airplane Mode for 10 seconds; restart the iPad.
Hotspot won’t work
Verify your plan includes tethering.
Turn Personal Hotspot off/on; change the password.
On the device connecting, “Forget” the hotspot network and reconnect.
Use Maximise Compatibility for older laptops or cameras.
Still stuck?
Reset Network Settings: Settings > General > Transfer or Reset iPad > Reset > Reset Network Settings (you’ll need to rejoin Wi‑Fi).
Reinstall the eSIM with the original QR/activation details.

Pro tip for work trips: If you manage multiple iPads for a team, our For Business solutions simplify bulk eSIM delivery and spend control. Partners and resellers can onboard via the Partner Hub.

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.

Press Roundup: Simology in the News (Q4 2025)

Q4 2025 was a busy season for Simology. Reporters, reviewers and travel editors zeroed in on two things: how quickly travellers can get connected with an eSIM before landing, and how to keep costs predictable during multi-country trips. This roundup summarises the themes in Simology press coverage from October to December, the product updates journalists highlighted, and a few quote snippets from our spokespersons that you may have seen. If you’re a writer on deadline, you’ll also find a practical media kit checklist and useful links to our most-requested pages, including Destinations, regional plan overviews such as Esim United States and Esim Western Europe, and our Partner Hub for assets and brand guidance. For business travel desks and ops teams, we’ve included pointers to For Business with team features, invoicing and centralised spend controls. Let’s get into what the media asked, what we shipped, and where to find the details fast.Where Simology showed up this quarterThe quarter’s coverage clustered around three practical use cases: short US trips, city breaks in Western Europe, and multi-stop itineraries across North America.North America: predictable connectivity for short staysEditors focussed on simple activation flows and predictable costs for domestic and cross-border travel.Useful links readers bookmarked:Esim United StatesEsim North AmericaCommon angles:“Install before you fly; switch on after landing.”“No surprise roaming add-ons from home carriers.”“Coverage that follows you across borders on one plan.”Western Europe: one plan, many countriesTravel desks emphasised the practicality of using a single eSIM for multiple countries, particularly over long weekends and rail itineraries.Popular pages cited:Esim Western EuropeEsim FranceEsim ItalyEsim SpainCommon angles:“No queueing for physical SIMs on arrival.”“Keep your primary number active for calls; use data on the eSIM.”“Clear allowances, easy top-ups mid-trip.”What journalists asked (and how we answered)Below are concise, on-record snippets from Simology spokespeople that appeared in Q4 pieces. Use them if you’re looking for fast, accurate phrasing.“An eSIM is simply a digital SIM. You scan a QR code, download the plan, and your phone adds a second data line in minutes.”“Our traveller-first approach is: show the networks up front, show the speeds you can expect, and make the total price obvious.”“For multi-country trips, a regional eSIM avoids the airport SIM shuffle. One plan, one dashboard, one top-up.”“Business teams want control without micromanaging devices. That’s why our admin console adds spend caps, shared wallets and consolidated invoices.”“We design for ‘install at home, switch on on arrival.’ That’s the easiest path to a smooth landing with maps, ride-hailing and messaging live.”Product updates the press highlighted in Q4Q4 saw a series of upgrades designed to make purchase, activation and management quieter and simpler. Here are the updates media tended to showcase:Cleaner activation flowQR code and install code both supported.Live preflight checks confirm device compatibility and OS settings before you pay.Smarter regional plan selectionDestination pages now recommend single-country vs regional bundles based on itinerary length.Regional plans cover border areas more reliably, helpful on rail and road trips.Business featuresTeam workspaces with central billing and one-click assignment.Exportable usage reports for finance.Policy tools to set data limits per user or per trip. See For Business.Partner resourcesUpdated logo suite, app screenshots and messaging guidelines. See the Partner Hub.Faster affiliate approvals and clearer deep-link parameters.Quick start checklist: install a Simology eSIM in under 2 minutesCheck your device supports eSIM and is carrier-unlocked.Choose your destination:Single country: e.g., Esim United States, Esim France, Esim Italy, Esim Spain.Multi-country: Esim Western Europe or Esim North America.Buy the plan; keep the QR code or activation code handy.On iPhone: Settings > Mobile Data > Add eSIM > Use QR/Activation code.On Android (may vary): Settings > Network & Internet > SIMs > Add eSIM > Use QR/Activation code.Label the new line “Travel Data,” set it as the data line, and leave your primary line for calls.Toggle “Data Roaming” on for the eSIM line. Leave primary line roaming off to avoid home-carrier charges.Land, switch airplane mode off, and your data should be live. If not, restart once.Pro tip: Install before you fly. Activation doesn’t start the clock; first network use does.The themes that drove coverageJournalists anchored their stories around a handful of practicality-first questions. Here’s how those mapped to what travellers care about.Can I keep my WhatsApp number? Yes. Your primary SIM/number remains. The eSIM supplies data only. Messaging apps continue as usual.Will I get 5G? Where available on the local network. Destination pages note expected network types. See Destinations for specifics.Is a regional pass worth it? If your itinerary crosses borders, one regional eSIM (e.g., Esim Western Europe) avoids per-country setup, with a single allowance to manage.What about business travel? Centralised control, per-trip budgets and consolidated billing save time versus expensing ad hoc SIMs. Details on For Business.What we shared with the press: practical guidance, not hypeRather than splashy claims, we emphasised the basics that save travellers time and money.Transparent pricing: all-in plan prices shown before checkout.Network disclosure: named networks where permitted, or capability bands where not.Predictable activation: installation at home; activation on arrival.Account portability: you can store multiple eSIMs and switch as you move between regions.Pro tip: If you’re comparing offers, look beyond headline GB. Check the fair use policy, tethering rules, and whether top-ups stack or reset.How to cover Simology: a mini media kit checklistIf you’re writing or filming a Simology piece, this checklist keeps assets and facts straight.Grab updated brand assets and device screenshots from the Partner Hub.Verify device support and OS flows using our live preflight check on any destination page, e.g., Destinations.Illustrate single-country vs regional with concrete examples:City break: Esim France or Esim Italy.Multi-country rail trip: Esim Western Europe.US + Canada itinerary: Esim North America.For B2B angles, request a demo account via For Business to explore admin controls.Need quotes or a technical explainer? Contact us via the Partner Hub with your deadline and focus; we’ll respond with verified details.Pro tip: Screenshare the install flow. Readers engage well with a 30-second “scan, install, label line, toggle data” segment—they can replicate it on their own devices.Traveller checklists the media lovedCoverage often embedded simple checklists. Here are two you can reuse.Pre-trip device checklistIs your phone carrier-unlocked?Does it support eSIM? (Most recent iPhone and Android flagships do.)Have you updated to the latest OS?Have you added a payment method to your app store or card-ready wallet?Did you save the QR code/activation code somewhere you can reach offline?First-hour on the groundDisable data roaming on your primary line (to avoid home-carrier roaming).Enable data roaming on the eSIM line.Open maps, ride-hailing and messaging to confirm everything is live.If you need tethering, check the plan’s hotspot allowance on your destination page.For teams: what editors flagged for business travellersBusiness travel coverage highlighted the trade-off between control and convenience.Central purchase, local experience: Ops buys plans in bulk; travellers self-install in minutes.Budget certainty: Shared wallets and caps prevent overspend.Compliance-friendly: Single monthly invoice with per-user breakdown.Global-ready: Mix regional passes across teams travelling to the US, Canada and Western Europe without juggling multiple vendors.Start here: For Business.Pro tip: Set policy at profile level (e.g., Sales 10 GB per week; Engineering 20 GB with hotspot) to cut manual approvals.Frequently asked questionsWhere can I see which countries and networks are supported?Head to Destinations for an A–Z view plus network details. For common trips, see Esim United States, Esim Western Europe and Esim North America.Do I need to wait until I land to install the eSIM?No—install at home so you’re set. Activation starts when the eSIM first connects to the local network.Can I keep my primary number active for calls and texts?Yes. Keep your primary line for calls/SMS; set the eSIM as your data line. Messaging apps continue to use your existing number.What happens if I run out of data mid-trip?You can top up from your account. Top-ups apply to the same eSIM profile and usually take effect within seconds.Is eSIM good for multi-country travel in Europe?Yes. A regional plan like Esim Western Europe covers multiple countries on one allowance and one install, so you avoid per-country SIM swaps.Do you support teams and company billing?Yes. Our business console offers centralised purchasing, allocations, spend controls and invoicing. See For Business.What’s nextIf you’re planning a trip or writing a guide, the fastest way to sense-check coverage, networks and allowances is to browse Destinations and pick your route. You’ll see plan options, setup steps and what to expect on the ground—no surprises.

Dual‑SIM Data Steering: Best Practices for iOS & Android

Travellers often juggle two priorities: staying reachable on their usual number and getting affordable, fast data abroad. Dual‑SIM (physical + eSIM or dual eSIM) makes that easy—if you set it up right. This guide shows you how to control which SIM handles voice, SMS and data, how to avoid accidental roaming charges, and how to keep apps like WhatsApp and banking OTPs working smoothly. We’ll cover iOS and Android step‑by‑step, explain default line rules, and share practical roaming presets you can apply in seconds. You’ll also find app‑specific tips and troubleshooting for common snags.If you’re new to travel eSIMs, browse country and regional options on Destinations, including ready‑to‑go packs such as Esim United States, Esim France, Esim Italy, Esim Spain, Esim Western Europe and Esim North America. Then use the dual sim data switching best practices below to keep costs down and coverage up.What “data steering” means on your phoneDual‑SIM data steering refers to how your device chooses a SIM for internet access, calls and messages, and whether it can switch between SIMs automatically. Key concepts:Default voice line: which SIM handles outgoing calls by default.Default SMS line: which SIM sends texts by default.Default data line: the only SIM that carries mobile data at any one time.“Allow mobile data switching” (iOS) / “Auto data switch” (Android): optionally lets the phone use the non‑data SIM for data during a call or when signal is poor.Data roaming per SIM: separate toggles to allow data outside your home network.Wi‑Fi assist / smart network switch: uses mobile data when Wi‑Fi is weak—useful, but can burn through data if you’re not careful.Your goal as a traveller is usually to keep your home SIM active for calls/SMS, and use a local/eSIM for data—without letting the phone sneak data onto the wrong SIM.Quick presets for travellersApply these simple presets to avoid bill shock and keep everything working:Pre‑trip 1. Install and label your travel eSIM. 2. Update apps and download offline maps on Wi‑Fi. 3. Confirm roaming SMS/call rates on your home SIM; disable data roaming on it.On landing 1.

You can keep WhatsApp registered to your home number while using data from your travel eSIM. - If WhatsApp needs re‑verification while abroad, you’ll need access to your home number via SMS or voice call. Keep your home SIM active for SMS (data roaming can remain OFF). - Don’t tap “Change Number” unless you truly want to move your account to a new number.Banking OTPs and 2FA - Many banks send OTPs via SMS to your home number. Keep the home SIM active with data roaming OFF so SMS can still arrive. - If your bank supports app‑based codes or a token, set that up before travel to reduce SMS dependence.iMessage and FaceTime - iMessage can use your Apple ID email as well as your number. In Settings > Messages > Send & Receive, tick your email to keep iMessage working even if your number can’t re‑activate. - If iMessage/FaceTime tries to re‑activate using SMS, ensure your home SIM can receive SMS.Android RCS (Chat features) - Google Messages’ RCS is associated with a specific number/SIM. You can keep RCS on your home number while mobile data comes from the travel eSIM—just ensure the home SIM remains active, and RCS is registered before you go.One‑time passwords from services - Expect some OTPs to arrive via SMS with delays when roaming. Have backup methods (authenticator app, email, or app approval) where available.Troubleshooting and pro tipsLock data to the correct SIM: Turn OFF “Allow Mobile Data Switching” (iOS) or “Auto data switch” (Android) during travel.Check APN settings: If data connects but is slow or drops, verify APN is auto‑filled per your eSIM instructions.Manually change networks: In some countries, one partner network is faster. Try manual network selection on the travel eSIM.Prefer LTE when 5G is patchy: Switching to LTE can improve stability and battery life.Only one data SIM at a time: Dual‑SIM Dual Standby means two lines are active for calls/SMS, but only one can carry mobile data.Background data control: Use Low Data Mode (iOS) or Data Saver (Android). Consider restricting heavy apps to Wi‑Fi.Hotspot with care: Tethering uses your default data SIM; verify your plan allows it.Frequent flyers: Keep a “Travel” profile ready to toggle—data to Travel, data roaming OFF on Home, auto switching OFF.Regional eSIMs: Multi‑country options like Esim Western Europe or Esim North America reduce mid‑trip SIM shuffling. For single‑country trips, pick Esim United States, Esim France, Esim Italy or Esim Spain.For teams and frequent travellersIf you manage staff on the road, set a standard preset: home SIM for calls/SMS, travel eSIM for data, roaming OFF on home SIM, and auto data switching disabled. Provide a simple runbook for iOS and Android.Centralise procurement and control with pooled eSIMs and usage reporting via For Business.If you’re a reseller or travel partner, explore co‑branded solutions through our Partner Hub.FAQWill changing the data SIM affect my phone number for calls or WhatsApp?No. Your phone number for calls/SMS stays on the SIM you set for voice. WhatsApp remains tied to the number it was registered with, regardless of which SIM provides data.Can I receive SMS on my home SIM with data roaming off?Yes. SMS uses the signalling channel, not mobile data. Keep the home SIM active and data roaming OFF to receive texts without using mobile data.Should I enable “Allow Mobile Data Switching” on iPhone while abroad?Usually no. Keep it OFF to prevent accidental data usage on your home SIM. Enable only if you need uninterrupted data during calls and you’re confident your home SIM won’t incur data charges.My travel eSIM shows signal but no data. What now?Toggle Airplane Mode, check APN, and ensure Data Roaming is ON for the travel eSIM. Try manual network selection to pick an alternative partner.Can I hotspot from my travel eSIM and still receive calls on my home number?Yes. Personal Hotspot uses the current default data line (travel eSIM), while your home SIM remains active for calls and SMS.Does my phone auto‑switch data to the “better” SIM when signal is poor?Only if you enable features like “Allow Mobile Data Switching” (iOS) or “Auto data switch” (Android). For cost control while roaming, keep these OFF.Next step: Pick your destination and get a travel eSIM that fits your trip on Destinations, then apply the presets above before you fly.
