eSIM Compatible Phones (Updated 2025): iPhone, Samsung, Pixel & More

30 Oct 2025

Travellers are ditching plastic SIMs for eSIMs because they’re fast to set up, kinder to your phone’s SIM tray, and usually cheaper than roaming. But eSIM support varies by model and region, and not every “dual-SIM” phone actually supports a digital SIM. This 2025 guide gives you the definitive compatibility picture: quick checks you can run in under two minutes, a brand-by-brand device matrix, and practical install tips that avoid airport Wi‑Fi panic. If you’re planning a trip to the US, Europe or beyond, we’ll also point you to dependable regional plans like Esim United States, Esim Western Europe and Esim North America.

Key point: model names alone aren’t enough. Variants from different countries or carriers can enable or disable eSIM. Use the quick checks below to confirm your exact device, then pick a plan from our global Destinations page.

The fastest way to confirm eSIM support (2‑minute check)

Step 1: Find your EID
iPhone: Settings > General > About. Look for “EID”.
Android (Pixel/Samsung/others): Settings > About phone (or Status). Look for “EID”.
Or dial *#06# on most phones. If you see an EID, your hardware supports eSIM.
Step 2: Look for an “Add eSIM” option
iPhone: Settings > Mobile Data > Add eSIM.
Samsung: Settings > Connections > SIM manager > Add eSIM.
Pixel/Android: Settings > Network & Internet > SIMs > + Add eSIM.
Step 3: Update and unlock
Install the latest iOS/Android update.
Ensure the phone is network unlocked for travel eSIMs.
Step 4: Dual SIM expectations
Most recent iPhones, Pixels and flagships support two lines active (one or two eSIMs depending on model). Mid‑range Androids may allow only one eSIM active alongside a physical SIM.

Pro tip: No EID showing? Your model or region variant likely doesn’t support eSIM, or the feature is disabled by firmware/carrier.

eSIM‑compatible phones in 2025: the definitive list

Model availability and eSIM features can vary by region and carrier firmware. Use this as a guide, then run the quick checks above on your exact handset.

Apple iPhone (global leaders for eSIM)

iPhone 16 / 16 Plus / 16 Pro / 16 Pro Max – eSIM supported; US models are eSIM‑only (no SIM tray).
iPhone 15 family – eSIM supported; US models are eSIM‑only.
iPhone 14 family – eSIM supported; US models are eSIM‑only.
iPhone 13, 12, 11 families – eSIM supported.
iPhone XS, XS Max, XR – first iPhones with eSIM.
iPhone SE (2nd gen 2020, 3rd gen 2022) – eSIM supported.

Notes for travellers: - iPhone 13 and newer can run two eSIMs simultaneously (or one eSIM + one physical SIM on non‑US models). - iOS allows storing multiple eSIM profiles and switching as you travel.

Samsung Galaxy (flagships and many A‑series)

Galaxy S24 / S23 / S22 / S21 / S20 series – eSIM supported on most global variants.
S20 FE: eSIM availability depends on edition/region; later “2022” models added eSIM in many markets.
Galaxy Z Fold and Z Flip (all generations since eSIM was introduced) – eSIM supported.
Galaxy Note20 / Note20 Ultra – eSIM supported on most variants.
Galaxy A‑series (region‑dependent): A55, A54, A35, A34, A25 5G, A15 5G and newer mid‑range models often include eSIM in Europe/Asia; some US carrier‑branded units disable it.

Notes for travellers: - eSIM on Samsung can be region/carrier dependent. Check Settings > Connections > SIM manager. - Many newer models support multiple stored eSIMs; simultaneous active lines vary by device/firmware.

Google Pixel (Android’s eSIM reference)

Pixel 9 / 9 Pro / 9 Pro Fold – eSIM supported.
Pixel 8 / 8 Pro – eSIM supported; dual eSIM possible on recent Android builds.
Pixel 7 / 7 Pro / 7a – eSIM supported.
Pixel 6 / 6 Pro / 6a – eSIM supported.
Pixel 5 / 4 / 4a – eSIM supported.
Pixel 3 / 3a – eSIM supported in many regions; some carrier variants limit it.
Pixel Fold – eSIM supported.

Notes for travellers: - Pixel 2 had a limited eSIM implementation (mostly Google Fi); treat it as non‑universal.
- Keep Android 13+ for the smoothest eSIM experience.

Other Android brands (selected models with widespread eSIM support)

Because eSIM on these brands varies more by market and firmware, treat this as “supported in many regions” and confirm on your device with the EID check.

OnePlus: 11, 12, 13 – eSIM on many EU/IN/global variants; earlier models largely lacked eSIM.
Sony Xperia: 1 V/VI, 5 V, 10 V/VI – eSIM widely supported.
Motorola: Razr (2019 onwards), Razr 40/50 series; Edge 30/40 families and newer – many variants support eSIM.
Xiaomi: 13 / 13 Pro / 13T Pro, 14 / 14 Pro / 14 Ultra – growing eSIM support by region; confirm locally.
OPPO: Find X5/X6/X7 series; Reno 8/10 series – selected regional variants support eSIM.
Huawei: Selected P and Mate series (e.g., P40/P50/P60, Mate 40/50) support eSIM in some markets.
Nothing: Phone (1) and Phone (2) support eSIM.
Fairphone: Fairphone 4 and 5 support eSIM.
Nokia/HMD: Nokia X30 5G, XR21 and some enterprise models support eSIM.

Pro tips: - Mid‑range and carrier‑branded Androids are the most inconsistent. Always check for EID and an “Add eSIM” option. - If your dual‑SIM tray has two physical SIM slots, eSIM may still be supported—but it’s not guaranteed.

iPhone vs Samsung vs Pixel on the road

iPhone
Best overall consistency. US iPhone 14/15/16 are eSIM‑only, which is ideal for travel plans.
iOS makes it simple to label lines (e.g., “Japan Data”) and pick a default for data/voice.
Can store multiple profiles; two lines active on iPhone 13 and newer.
Samsung
Powerful SIM manager with clear toggles for data/voice/roaming.
Watch for model/region variance on A‑series and FE models.
If “Add eSIM” is missing, update software; some regions enable it via firmware.
Pixel
Clean implementation with helpful prompts; strong dual‑SIM standby on recent models.
Updating to the latest Android build often unlocks dual eSIM improvements.
Great for quick QR installs before you fly.

- Business travellers: centralise purchasing and compliance with For Business.

Troubleshooting and gotchas

No “Add eSIM” option
Update software; reboot; check if the phone is carrier‑branded (some carriers hide the menu on mid‑range models).
No EID found
Your device likely lacks eSIM hardware or the variant disables it.
QR won’t scan
Enter activation details manually. Ensure you’re on Wi‑Fi and any VPN is off.
“Maximum eSIMs reached”
Delete old, unused eSIM profiles to free a slot.
Data not working on arrival
Confirm the travel eSIM is set as the Mobile Data line and Data Roaming is on. Reboot once after network attach.
Locked phone
Travel eSIMs require an unlocked device. Contact your carrier to request unlock before you fly.

FAQ

How do I know if my phone is eSIM capable?

Check for an EID in Settings (or dial *#06#) and an “Add eSIM” option in your SIM settings. If both exist, your phone supports eSIM. If either is missing, it likely doesn’t.

Do I need an unlocked phone to use a travel eSIM?

Yes. Most travel eSIMs, including Simology plans, require an unlocked device. A carrier‑locked phone generally only accepts that carrier’s eSIMs.

Can I run two lines at the same time?

Most modern iPhones (13 and newer) and recent Pixels/Samsungs support two active lines (e.g., personal number plus travel data). Some mid‑range Androids limit you to one active eSIM at a time.

How many eSIMs can I store?

It varies by model. Recent iPhones and Pixels can store multiple eSIM profiles (often 5–10 or more) but typically allow only two lines active simultaneously. You can switch profiles in Settings.

Can I move an eSIM to a new phone?

Some providers support eSIM transfer in‑app or via QR reissue, but many treat eSIMs as one‑device only. Plan to install a fresh eSIM on your new phone.

Will eSIM drain my battery faster?

Not noticeably. Running two lines can use slightly more power, but modern radios manage this efficiently. Most users won’t see a meaningful difference.

Next step: Confirm your phone with the quick checks above, then pick your destination plan on Destinations.

Andes Highlights (3 Weeks): Peru–Bolivia–Chile–Argentina Connectivity

Planning a south america itinerary 3 weeks through the high Andes? This route stitches together Peru’s Sacred Valley, Bolivia’s La Paz and Salar de Uyuni, Chile’s Atacama Desert, and northern Argentina’s quebradas or Mendoza wine country—often by long-distance bus and a couple of short flights. Connectivity is different at altitude: coverage is strong in cities but drops in high passes and salt flats; bus Wi‑Fi is patchy; border towns can be blackspots. The smart move is an eSIM with multi‑country coverage, backed by offline maps, offline translations, and a simple routine for crossing borders by bus without losing service. Below you’ll find a practical, connectivity-first itinerary; checklists to prep your phone, apps and documents; and on-the-ground tips for staying online where it matters: booking transport, hailing taxis, backing up photos, and navigating when the signal disappears.If you’re transiting via Europe or North America, you can also add a layover eSIM to stay connected door-to-door. Start with our country list on Destinations, then follow the steps, and you won’t waste time chasing SIM shops at 3,500 metres.The 3‑week Andes route at a glanceWeek 1: Peru (Cusco, Sacred Valley, Machu Picchu) - Fly into Cusco (or Lima then connect). - Base in Cusco; day trips to Pisac/Chinchero/Maras–Moray. - Train to Aguas Calientes; Machu Picchu visit; return to Cusco or continue to Puno/Lake Titicaca.Week 2: Bolivia and Chile (La Paz, Uyuni, San Pedro de Atacama) - Bus/collectivo via Copacabana to La Paz. - Fly or overnight bus to Uyuni. - 3‑day Uyuni–altiplano tour ending in San Pedro de Atacama (Chile).Week 3: Chile and Argentina (Atacama to Salta or Mendoza/Buenos Aires) - Choose: - North: San Pedro to Salta/Jujuy by bus; fly to Buenos Aires. - Or South: San Pedro–Calama flight to Santiago; bus or flight to Mendoza; onward to Buenos Aires.Connectivity notes (quick): - Cities: generally strong 4G/4G+; 5G in major hubs (Santiago, Buenos Aires). - Altitude/rural: expect long no‑signal stretches (Uyuni, altiplano passes, Paso Jama). - Bus Wi‑Fi: often advertised, rarely reliable. Plan to be offline onboard. - Border regions: networks switch; a multi‑country eSIM avoids sudden loss.eSIM vs local SIMs for a 4‑country tripFor a route with multiple borders and remote legs, eSIM wins on time and reliability.What a multi‑country eSIM gets you: - One plan across Peru, Bolivia, Chile, Argentina (check coverage per country on Destinations). - No passport/SIM registration queues at kiosks. - Keep your home number active on the physical SIM for calls/SMS codes. - Instant top‑ups if you burn data on photos or navigation.When a local SIM still helps: - Long stay in one country with heavy data use (e.g., a month in Buenos Aires). - Dead zones where a different local network performs better (rarely worth the hassle on a 3‑week pace).Practical approach: - Use an eSIM as your primary data line across all four countries. - If you find a specific local network far better in one region, add a cheap local SIM and keep the eSIM as backup.Device readiness checklist (before you fly)1) Check eSIM compatibility and SIM‑lock status on your phone.2) Buy and install your eSIM while on home Wi‑Fi. Keep a PDF/printed copy of the QR code.3) Label lines clearly (e.g., “eSIM Andes Data”, “Home SIM”).4) Turn on data roaming for the eSIM; leave roaming off for your home SIM to avoid charges.5) Set up dual‑SIM rules: data on eSIM; calls/SMS default to home SIM if needed.6) Download offline: Google Maps/Organic Maps for all target regions; language packs (Spanish at minimum); bus/air tickets; hotel confirmations.7) Cloud backups: set to upload on Wi‑Fi only; pre‑create shared albums for travel companions.8) Test tethering/hotspot with your laptop/tablet.If you’re transiting popular hubs, consider a short layover eSIM: - USA connections: add an Esim United States or a broader Esim North America.- Europe connections: Madrid/Barcelona? Use an Esim Spain. Paris or Rome? See Esim France and Esim Italy. Multi‑country layovers? Try Esim Western Europe.City‑by‑city connectivity notesCusco & the Sacred Valley (Peru)Coverage: Good in Cusco city; variable in high villages (Maras/Moray) and along Inca Trail approaches.Tips: Download Sacred Valley maps offline; pin viewpoints and ruins. most taxis use WhatsApp—save your accommodation’s number.Machu Picchu/Aguas Calientes: Patchy to none at the citadel. Upload your photos later; don’t rely on live ticket retrieval.Lake Titicaca: Puno and CopacabanaPuno: Reasonable 4G; bus terminals crowded—screenshot QR tickets.Crossing to Copacabana: Expect a signal drop around the border; have directions saved offline.La Paz (Bolivia)Good urban 4G; the cable car network has decent signal but tunnels do not.Yungas/“Death Road” tours: Mountain valleys cause dead zones—share your emergency contacts with the operator, carry a charged power bank, and don’t plan remote calls.Uyuni and the Altiplano (Bolivia to Chile)Uyuni town: OK 4G; ATMs finicky—use Wi‑Fi for banking apps.Salt flats/lagunas: Assume offline for most of the 3‑day tour. Guides often carry satellite phones; agree a pickup time/place in San Pedro and preload your map route.San Pedro de Atacama (Chile)Town: Solid 4G; accommodations often have Wi‑Fi but speeds vary.Geysers, Valle de la Luna: Offline navigation essential; sunrise trips start before mobile networks wake up in some areas.Salta/Jujuy or Mendoza/Buenos Aires (Argentina)Salta/Jujuy: Good city coverage; quebradas have long no‑signal sections.Mendoza: City 4G/5G; vineyards outside town can be patchy.Buenos Aires: Strong 4G/5G; ideal for cloud backups and large downloads before you fly home.Border crossings by bus: step‑by‑stepThe big ones on this route: Peru–Bolivia (Puno/Copacabana), Bolivia–Chile (Uyuni–San Pedro via Hito Cajón), Chile–Argentina (Paso Jama to Salta or Los Libertadores to Mendoza).How to keep service and sanity:1) The day before:- Top up your eSIM data.- Confirm your plan includes both countries you’re entering/leaving.- Download offline maps for both sides of the border and your town of arrival.- Save bus company WhatsApp and terminal address offline.2) On departure morning:- Keep a paper copy or offline PDF of tickets, insurance, and accommodation proof.- Charge phone and power bank; pack a short cable in your daypack.3) On the bus:- Don’t count on bus Wi‑Fi. Keep your eSIM as primary, but expect drops near mountain passes.- If your phone supports it, enable “Wi‑Fi calling” for later when you reach accommodation Wi‑Fi.4) At the border posts:- Data may be unavailable. Keep QR codes and booking numbers offline.- After exiting one country and entering the next, toggle Airplane Mode off/on to re‑register on the new network.- If the eSIM doesn’t attach, manually select a network in Mobile Settings.5) Arrival:- Send your accommodation a quick WhatsApp when you’re back online.- Recheck your eSIM’s data roaming is on; confirm you’re on an in‑country network, not a weak roaming partner.Pro tips: - Dual profiles: If your eSIM allows, keep a secondary profile for a different network in the same country—helpful in border towns.- Cash buffer: Some border terminals don’t accept cards; download a currency converter for offline use.Offline survival kit (5‑minute setup)Maps: Download regions for Cusco, Sacred Valley, Puno, La Paz, Uyuni, San Pedro, Salta/Jujuy or Mendoza, and Buenos Aires.Translations: Download Spanish for offline use; add phrasebook favourites (bus tickets, directions, dietary needs).Documents: Save PDFs of passports, tickets, hotel addresses; star them for quick access.Rides: Screenshots of pickup points; pin bus terminals and hotel doors.Entertainment: Podcasts and playlists for long bus legs, set to download on Wi‑Fi only.Altitude and your tech: what changesCoverage gaps lengthen: Fewer towers at high altitude; valleys can block signal. Assume offline on remote excursions.Batteries drain faster in cold: Keep your phone warm and carry a power bank (10,000–20,000 mAh).Hotel Wi‑Fi may be congested: Schedule big uploads (photo backups, app updates) for big-city stays like Santiago or Buenos Aires.GPS still works offline: Your blue dot shows on offline maps without data—preload everything.Data budgeting for 3 weeksTypical traveller usage across this route: - Messaging/Maps/Bookings: 0.2–0.5 GB/day- Social and photo sharing: 0.3–0.7 GB/day- Occasional video calls/streaming: 0.5–1.0 GB/dayFor a mixed-use trip, plan 15–25 GB for 3 weeks. Heavy creators should double it and upload over hotel Wi‑Fi when possible. If you work remotely, consider a higher‑capacity plan and a backup eSIM; see our guidance on For Business.Practical route with transport and connectivity cuesDays 1–4 Cusco base: Strong city signal; day trips may be spotty—go offline-ready.Days 5–6 Machu Picchu: Expect no service at the ruins; sync tickets ahead.Days 7–8 Puno to La Paz via Copacabana: Border signal drop; re‑register networks after crossing.Days 9–11 Uyuni tour to San Pedro: Treat as offline; charge nightly; carry spare cables.Days 12–14 San Pedro: Stable in town; tours offline; top up data before Paso Jama.Days 15–17 Salta/Jujuy or Mendoza: Good urban 4G; rural patches are offline.Days 18–21 Buenos Aires: Strongest connectivity of the trip; clear your uploads and map downloads for the flight home.Partnering and stopover extrasHospitality and tour operators in the Andes: help your guests stay connected—explore co‑branded solutions via our Partner Hub.Transatlantic flyers: test your eSIM setup on a layover with an Esim United States or Esim Western Europe before hitting high-altitude blackspots.FAQs1) Do I need a local SIM in each country?No. A multi‑country eSIM covering Peru, Bolivia, Chile and Argentina is simpler and works well for a 3‑week pace. Consider a local SIM only if you’ll spend longer in one country and want the absolute best regional coverage.2) Will my WhatsApp number change with an eSIM?No. WhatsApp is tied to your registered number, not your data line. Keep your home SIM active for voice/SMS (roaming off if you wish), and use the eSIM for data—WhatsApp continues as normal.3) Can I hotspot to my laptop or camera?Yes. Enable tethering on your eSIM. Mind your data: cloud backups and OS updates can burn gigabytes—set them to Wi‑Fi only or schedule in big cities.4) What if there’s no signal on the Uyuni/Atacama legs?That’s expected. GPS still works offline. Pre-download maps and translations, carry a power bank, and sync plans with your tour operator before departure.5) Will I get roaming charges at borders?If you’re using a multi‑country eSIM with coverage in both countries, you won’t incur extra roaming fees from your home carrier. Keep roaming off on your home SIM to avoid accidental use.6) I’m connecting via Europe or the US—worth getting a layover eSIM?Yes. It’s an easy way to test your setup and stay reachable. Try Esim North America or country options like Esim Spain, Esim France, or Esim Italy for common hubs.Next step: Browse South America coverage options and build your plan on Destinations.

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 casesWork and personal separationKeep 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 dataKeep your home SIM active for banking OTPs, two-factor codes and critical calls.Add a local or regional eSIM for affordable 4G/5G data and local rates.Disable data roaming on your home line to avoid bill shock; use the travel eSIM for all data.Pick country plans like Esim United States, Esim France, Esim Italy or Esim Spain, or choose a multi-country pass such as Esim Western Europe or Esim North America. Explore more via Destinations.Coverage and cost optimisationUse 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 projectsProvision 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 behaveUnderstanding 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 eSIMiPhone step-by-stepObtain your eSIM details: QR code or activation code from your provider.On iPhone, go to Settings > Mobile Data > Add eSIM (or “Add Data Plan”).Scan the QR code or enter details. Wait for activation.Label your lines (e.g., “Personal” and “Travel”). Clear labels prevent mistakes.Choose defaults: - Default Line for Calls and SMS. - iMessage & FaceTime line. - Mobile Data line (set to your travel/local eSIM when abroad).Toggle “Data Roaming”: - Turn off for your home line while travelling. - Turn on for your travel eSIM, if required.Optional: Enable “Allow Mobile Data Switching” if you want automatic fallback.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)Get your eSIM QR/activation details from your provider.Open Settings > Network & Internet (or Connections) > SIMs > Add eSIM.Scan the QR code or enter details. Wait for activation.Name each SIM (e.g., “Work” and “Data”).Set preferences: - Preferred SIM for Calls. - Preferred SIM for SMS. - Preferred SIM for Mobile Data (set to the travel/local eSIM).Roaming: - Disable data roaming on your home line. - Enable on your travel eSIM if needed.Optional: Enable “Switch data automatically” or similar to allow fallback.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 reachableBefore 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 gotchasKeep 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 travellersCity breaks or rail trips across multiple EU countries: Choose Esim Western Europe to avoid juggling separate plans.US road trip or conferences: Use Esim United States for nationwide coverage; combine with your home line for OTPs.Canada/US/Mexico multi-stop: Try Esim North America for cross-border continuity.Single-country travel: See Esim France, Esim Italy and Esim Spain for local choices, or browse the full list via Destinations.Business travel at scale: Central provisioning, spend control and support via For Business; partners can onboard faster with the Partner Hub.FAQsCan 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.Next step: Plan your trip and pick the right travel eSIM by browsing Destinations.

Billing & Finance Ops: VAT Invoices, Multi‑Currency, and Refund Flows

Getting eSIM billing right isn’t just about taking payments—it’s about trust, compliance, and clarity for travellers and partners at scale. This guide covers the practical building blocks of esim vat invoicing multi currency operations: how to handle VAT/Sales Tax by region, present FX cleanly, calculate pro‑rations fairly, and run refund, chargeback, and dunning flows that reduce friction. Whether you’re a marketplace, reseller, MNO/MVNO, or travel brand, the goal is the same: ship fast, stay compliant, and keep customer effort low. We’ll walk through usable checklists and decision points, and point to where Simology supports your commerce stack—across destinations like Esim Western Europe, Esim North America, and single‑country packs such as Esim United States, Esim France, Esim Italy, and Esim Spain. For partnership options and operational tooling, see For Business and our Partner Hub.Why billing precision matters for eSIM at scaleTax compliance varies by region and buyer type. Poor handling risks fines or blocked payouts.Travellers expect local currency clarity and transparent FX—especially when buying on the move.Pro‑rations and top‑ups must feel fair; opaque maths is a refund magnet.A clear refund and chargeback playbook minimises losses and disputes.Strong dunning keeps B2B/wholesale cashflow healthy without harming relationships.VAT invoicing essentials for eSIM providers and partnersIdentify tax nexus by regionEU/UK: B2C digital services are typically VATable where the customer is located; B2B may use reverse charge if a valid VAT number is provided.US/Canada: Sales tax/GST/HST/PST rules vary by state/province and product classification; marketplace vs. seller of record impacts liability.APAC/ROW: Several countries operate VAT/GST on digital services to local consumers. Thresholds and registration rules differ.Note: Always validate assumptions with your finance team and align seller‑of‑record responsibilities in partner contracts.Data you must capture on a VAT‑compliant invoiceSeller legal name, address, and tax registration (e.g., VAT ID).Buyer details; collect VAT number for B2B where applicable.Unique invoice number, issue date, supply date (if different).Line items: product name (e.g., “eSIM 5 GB – France”), quantity, unit price, discounts.Tax rate and amount per line, and total tax.Currency of account and any FX conversion basis.Notes: reverse charge wording (when applicable), credit note references for refunds.Step‑by‑step: Configure VAT and invoice rulesDefine seller‑of‑record per market and channel (direct vs. reseller).Configure tax determination: by billing address, IP/geo, payment BIN, or combined evidence.Set B2B logic: VAT number capture, real‑time validation, and reverse charge handling.Attach tax codes to catalogue SKUs by region (e.g., EU digital service vs. US telecom).Generate VAT invoices on payment capture; issue credit notes on refunds.Store signed PDFs plus machine‑readable data (e.g., CSV/JSON) for audit.Provide travellers with self‑serve invoice downloads via order history.Pro tip: When selling cross‑border packs like Esim Western Europe, ensure your SKU structure supports per‑buyer tax determination even if the product spans multiple countries.Multi‑currency pricing and FX display that customers trustDisplay vs settlement currencyDisplay currency: what the shopper sees at checkout (e.g., EUR, GBP, USD, CAD).Settlement currency: what your gateway pays out in (often USD or EUR).Show the display currency by user location or browser currency, but disclose when settlement occurs in a different currency.Pro tip: Present a single total in the shopper’s local currency with tax included for B2C. For B2B, show net, tax, and gross with the buyer’s VAT status clearly flagged.Rounding, fees, and rate sourcesUse a consistent FX source (e.g., daily mid‑market rate plus a disclosed margin).Round prices to local conventions (e.g., .99, or 0.05 increments where applicable).Clearly disclose any FX mark‑up and that the card issuer may apply additional conversion fees.Step‑by‑step: Implement multi‑currency in your checkoutDetect preferred currency from locale and BIN, allow manual override.Convert base prices using your rate source and cache rates for the day.Compute taxes in the display currency; track base currency equivalents for accounting.Apply rounding rules per currency; store pre‑ and post‑round values.Show a plain‑English FX note (e.g., “Billed in USD; amounts shown in EUR for your reference” where relevant).Reconcile settlements: map PSP payouts in the settlement currency back to order‑level FX snapshots.Pro tip: Keep the FX snapshot (rate ID, timestamp, margin) on each order to simplify refunds and audits.Pro‑rations, expiries, and top‑upsCommon scenarios and calculationsMid‑cycle upgrade to a larger data pack: charge a pro‑rated difference based on remaining days or unused data value.Early cancellation (goodwill): offer a pro‑rated credit note based on unused data/validity.Auto‑renewal cancellations before renewal date: no proration; ensure clean cancellation messaging.Top‑ups: treat as separate SKUs with their own tax rules; avoid recalculating tax on the original order.Two pro‑ration models - Time‑based: Value remaining = price × (days remaining ÷ total days). - Usage‑based: Value remaining = price × (unused data ÷ total data).Pro tip: Pick one model per product family and document it in the checkout and invoice notes to avoid disputes.Refund and chargeback flows that reduce frictionRefund policy matrixTechnical failure (e.g., profile never delivered/activated): full refund.Partial usage but network issues verified: partial refund or goodwill credit.Buyer error (wrong device/region) with no usage: one‑time goodwill refund to reduce chargeback risk.Fraud or card testing: block and no refund; share device/usage fingerprints with your PSP.Always issue a credit note matching the original tax treatment and currency.Step‑by‑step: Process a refundVerify eligibility: review activation logs, usage, and support notes.Select type: full, partial (amount or percentage), or voucher credit.Calculate tax reversal: mirror original tax rate and FX snapshot.Create credit note linked to the original invoice; include reason code.Execute refund via PSP in the original payment method and settlement currency.Notify the customer with clear timelines (e.g., “3–10 business days depending on bank”).Pro tip: For travellers buying local packs like Esim France or Esim United States, add geo‑tips in the confirmation email (device compatibility, APN steps). Fewer setup issues mean fewer refund requests.Chargeback playbookPreventionStrong descriptor: include “Simology eSIM” and support URL.3‑D Secure where available; AVS/CVV checks and velocity rules.Pre‑delivery device checks (e.g., eSIM capability).Evidence for representmentOrder details, IP/device fingerprint, and BIN country match.Delivery proof: eSIM QR/profile delivered timestamp.Usage logs (data session started), and T&Cs acceptance.Customer communications and refund policy shown at checkout.TriageLow‑value/high‑cost disputes: consider concession.High‑value/clear evidence: proceed to representment with focused docs.Post‑mortemUpdate fraud rules (e.g., block risky BIN ranges, disposable emails).Feed learnings into support macros and checkout copy.Pro tip: Create reason‑code playbooks (e.g., “product not received” vs. “fraudulent”). Standardise the evidence pack to submit within 48 hours.Dunning and collections for B2B and wholesalePractical timeline and commsDay 0: Invoice issued with net terms (e.g., Net 14/30). Include payment link, bank details, currency, and tax breakdown.Day 3 before due: Friendly reminder with statement of account.Day 0 due: Notice with next steps and escalation path.Day 7 overdue: Second reminder; offer card-on-file as a fallback.Day 14–21 overdue: Account manager call; agree a payment plan.Day 30+: Suspend non‑critical benefits (marketing funds, new activations) while preserving active travellers where possible.Pro tip: For resellers sourcing regional packs like Esim North America or Esim Western Europe, suspend new order creation before disabling existing lines to avoid traveller impact.Risk controls and suspension logicCredit limits per partner; auto‑adjust based on payment history.Collateral or prepayment for new partners until two clean cycles.Grace windows for active travellers; offer top‑up vouchers funded from security deposit if needed.Automated dunning across email + portal banners; keep comms factual and friendly.Regional nuances to watchEU/UK: Display VAT‑inclusive prices for consumers. If a B2B buyer enters a valid VAT number, apply reverse charge and show required wording on the invoice.US: Product taxability differs by state; telecom vs. digital service classification can change rates. Marketplace facilitator laws may shift liability.Canada: GST/HST/PST mix varies by province; register thresholds apply.Travellers often buy in one country for use in another (e.g., purchase from the UK for Esim Spain). Determine tax based on customer location rules, not the visited country, unless local laws require otherwise.Multi‑country bundles: Use consistent SKUs tied to the buyer’s location for tax, not each covered country.Pro tip: Keep your plan catalogue aligned with geo coverage on Destinations so tax and pricing logic stays in sync with what travellers actually buy.Reporting, reconciliation, and auditsDaily reconciliation checklistMatch orders to payments: amount, currency, fees, settlement date.Verify tax amounts by jurisdiction and product SKU.Confirm invoice and credit note sequences are gap‑free.Review refunds vs. payouts; reconcile FX differences to a gain/loss account.Surface anomalies: negative margin orders, duplicate refunds, or out‑of‑policy credits.Export formats and storageProvide CSV/JSON exports per day/week with:Order ID, SKU, region, buyer type (B2B/B2C), FX rate used.Net, tax, gross, currency, settlement currency, fees.Invoice/credit note numbers and links.Retain PDFs and raw data per statutory timelines; ensure timezone consistency across logs.Pro tip: Store an immutable “tax calc snapshot” per order so later tax engine changes don’t alter historical documents.Quick setup checklist (save this)Define seller‑of‑record per channel/region.Map tax codes per SKU and integrate VAT number validation.Implement display currency with clear FX notes; keep settlement currency stable.Choose a single pro‑ration model and document it.Automate credit notes for refunds; mirror original tax and FX.Build a reason‑coded chargeback pack and a 30‑day dunning cadence.Reconcile daily; export audit‑ready tax and payout data.FAQQ1: How should I handle VAT for B2B eSIM sales in the EU/UK? A: Collect and validate the buyer’s VAT number at checkout. If valid, apply reverse charge and include the correct wording on the invoice. If not, charge VAT as for B2C. Keep the validation result with the order.Q2: Can I show prices in multiple currencies but settle in USD or EUR? A: Yes. Use a stable settlement currency operationally, show shopper‑friendly display currencies, and disclose the settlement currency and any FX margin. Keep the FX snapshot per order for refunds and audits.Q3: What’s the fairest way to calculate partial refunds on data packs? A: Pick one method and be consistent. Time‑based works well for validity‑driven plans; usage‑based suits metered data. Mirror the original tax and FX when issuing the credit note.Q4: How do I reduce “product not received” chargebacks? A: Send a post‑purchase email with device compatibility checks, clear activation steps, and support links. Keep delivery logs of the eSIM profile and show your refund policy at checkout. For country packs like Esim Italy, add country‑specific APN tips.Q5: What should a VAT invoice include for eSIM? A: Seller and buyer details (including VAT IDs), unique invoice number, dates, line‑item prices, tax rates and amounts, totals, currency, and any reverse charge text. Issue credit notes for any refunds.Q6: How should dunning work for wholesale partners? A: Use a clear cadence (reminders before and after due), offer multiple payment methods, set credit limits, and suspend new activations before impacting existing travellers.
