How to Set Up an eSIM on iPhone 15/16: Step-by-Step with Fixes

30 Oct 2025

Travelling with an iPhone 15 or 16? Good news: Apple’s eSIM experience is now fast, reliable and ideal for travellers who want local data without juggling plastic SIMs. This guide walks you through a clean, repeatable iPhone eSIM setup, including QR code install, manual activation details (SM‑DP+), carrier app installs and Quick Transfer. You’ll also find practical APN tips, a fixes section for the most common errors, and pro traveller settings so data just works the moment you land. If you hit a snag at any point, jump straight to Troubleshooting below.

If you’re still shopping for a plan, browse country and regional options on Destinations — from single-country picks like Esim United States, Esim France, Esim Italy or Esim Spain to multi-country passes like Esim Western Europe and Esim North America.

Before you start: what you need

Estimated time: 5–10 minutes
Cost: Free to install (plan cost varies)

An iPhone 15 or iPhone 16 running current iOS (Settings > General > Software Update).
Reliable Wi‑Fi (strongly recommended during activation).
Your eSIM details:
Either a QR code, or
Manual activation details: SM‑DP+ address, Activation Code, and (if provided) Confirmation Code.
If transferring from another iPhone: both phones on iOS 16+ and signed into iCloud with Bluetooth on.

Quick checks: - Remove any old VPN profiles (Settings > General > VPN & Device Management) if they may interfere. - Backup screenshots or a PDF of your QR code so you have it offline on arrival.

Compatibility note: - iPhone 15/16 models sold in the United States are eSIM‑only. International variants generally still include a physical SIM tray. All support multiple eSIMs with up to two lines active at the same time.

Step-by-step iPhone eSIM setup

You can add an eSIM in four ways. Use the method your provider supports.

Tip: If your provider instructs you to activate only after you land, you can still pre‑install the eSIM over Wi‑Fi and toggle it on later.

Option 1: Install via QR code (fastest)

Connect to Wi‑Fi.
On your iPhone: Settings > Mobile Data (Cellular) > Add eSIM.
Tap Use QR Code and point the camera at your code.
When prompted, tap Continue. If asked, choose to Add eSIM.
Wait for “Activating” to complete. This can take 1–3 minutes.
Label the line (e.g., “Japan data”).
Set as your Mobile Data line if it’s your travel plan. Keep your home line for calls/SMS if needed.
Leave Data Roaming off until you arrive, unless your plan requires activation at purchase.

If you see “Invalid QR Code” or “Plan Cannot Be Added”, see Troubleshooting.

Option 2: Enter details manually (SM‑DP+ and Activation Code)

Settings > Mobile Data > Add eSIM > Use QR Code > Enter Details Manually.
Enter: - SM‑DP+ Address: e.g., “xyz.smdp.com” (exactly as provided) - Activation Code: long string (case‑sensitive) - Confirmation Code: only if your provider lists one
Tap Next and wait for activation.
Label and assign the line for data as needed.

Tip: Typo‑sensitive. Copy/paste carefully. Double‑check dots and dashes.

Option 3: Install via carrier/app

Install your provider’s app from the App Store.
Create/log in to your account and purchase/assign the eSIM to your device.
In the app, select “Install eSIM” and follow the prompts.
When iOS prompts to add the plan, confirm and wait for activation.

Option 4: eSIM Quick Transfer (moving from your old iPhone)

Put both iPhones side by side with Bluetooth on and signed into iCloud.
On your new iPhone: Settings > Mobile Data > Add eSIM > Transfer From Nearby iPhone.
On your old iPhone, approve the transfer and choose the line.
Wait for activation on the new device and confirm the line is working.
Decide whether to keep the eSIM active on the old phone (usually off for travel).

After activation: configure for travel

These post‑install settings make the difference between “it works” and “it works every time”.

Label lines: Settings > Mobile Data > tap the new plan > Label.
Default line:
Mobile Data: choose your travel eSIM.
Voice: choose your home line if you want your usual number active.
iMessage & FaceTime: Settings > Messages/FaceTime > Send & Receive > pick the appropriate number/email.
Data Roaming: Toggle on when you land in your destination.
Network Selection: If auto fails, try manual. Settings > Mobile Data > Network Selection > turn off Automatic and choose a listed partner network.
5G/LTE: Settings > Mobile Data > Mobile Data Options > Voice & Data > try 5G Auto/On or LTE per provider guidance.
Low Data Mode: Turn off if speeds seem throttled unnecessarily.

APN and data settings (only if needed)

Most eSIMs auto‑configure APN. If data connects but webpages won’t load, set APN manually.

Go to Settings > Mobile Data > your eSIM plan > Mobile Data Network (Cellular Data Network).
Under Mobile Data (Cellular Data):
APN: enter the exact APN value provided (e.g., “internet”, “fast.t-mobile.com” — this will vary).
Username/Password: leave blank unless specified.
MMS/Personal Hotspot APNs: set only if you’ve been given values.
Return one level and reboot the iPhone if the change doesn’t apply immediately.

Pro tips: - If the APN field is missing or greyed out, your profile is locked by the carrier; contact support to push correct settings. - “Could not activate mobile data network” usually means incorrect APN or temporary network registration delay. Recheck APN and toggle Airplane Mode for 20 seconds.

Troubleshooting: top errors and fast fixes

If activation fails, work methodically. Most issues resolve in under 5 minutes.

1) “Invalid QR code” / “This code is no longer valid” - Cause: Code already redeemed, expired, or scanned incorrectly. - Fix: - Confirm you’re scanning the most recent QR from your provider. - Try Enter Details Manually (SM‑DP+, Activation Code). - Ask the provider to reissue the eSIM.

2) “Activation unsuccessful” / Stuck on “Activating” - Cause: Wi‑Fi glitch or temporary carrier server timeout. - Fix: - Force‑quit Settings, toggle Airplane Mode on for 20 seconds, then off. - Reboot iPhone. - Switch to a different Wi‑Fi or use a known‑good hotspot. - Try again after 10–15 minutes.

3) “No Service” after install - Cause: Roaming off, wrong network selected, unsupported band, or not yet in the coverage area. - Fix: - Toggle Data Roaming on (when in destination). - Settings > Mobile Data > Network Selection: try manual selection of a partner network. - Settings > Mobile Data Options > Voice & Data: switch between 5G Auto, 5G On, and LTE. - Restart the iPhone.

4) Data doesn’t work; calls/SMS do (or vice‑versa) - Cause: APN not set, wrong default data line, or plan is data‑only. - Fix: - Confirm your eSIM is selected as the Mobile Data line. - Set APN manually as provided by the carrier. - If your plan is data‑only, use OTT apps for calls/messages.

5) “Plan cannot be added” / “Unable to complete cellular plan change” - Cause: Region/IMEI/EID mismatch or unsupported device profile. - Fix: - Ensure you’re on the latest iOS. - Provide your device EID to the provider (Settings > General > About). - Ask the provider to reprovision the eSIM.

6) “Could not activate mobile data network” - Cause: APN or temporary network block. - Fix: - Reenter APN, then reboot. - Toggle Airplane Mode, then test again. - Try manual network selection.

Still stuck? Delete and reinstall the eSIM: - Settings > Mobile Data > tap the plan > Remove eSIM. Re‑add via QR/manual details. Ensure Wi‑Fi is stable during reactivation.

Managing multiple eSIMs on iPhone 15/16

Store many, use two: iPhone 15/16 can store multiple eSIMs and keep up to two lines active at once.
Switch data line quickly: Settings > Mobile Data > Mobile Data > select the plan you need.
Pause a line (don’t delete): Toggle “Turn On This Line” off to keep the profile for later.
Delete when finished: Remove eSIM to tidy your list. Keep a copy of the QR/manual details in case you need to reinstall.

Pro tips for travellers

Pre‑install on Wi‑Fi before you fly, then toggle the line on when you land.
Keep your home line on for SMS codes, but set the travel eSIM as the Mobile Data line.
Save the QR code and manual details offline (Files app/Notes) for airport re‑installs.
If speed dips in crowds, try manual network selection or switch between 5G and LTE.
Hotspot/tethering: Check your plan allows it; if not working, set the APN for Personal Hotspot if provided.

Plan your eSIM by destination

Choose a country or a multi‑country pass based on your route: - Single countries: Esim United States, Esim France, Esim Italy, Esim Spain - Multi‑country: Esim Western Europe, Esim North America

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

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

eSIM for USA Travel (Tourists): Best Options & Setup

Planning a trip to the United States and want reliable data without hunting for a SIM at the airport or paying roaming fees? An eSIM is the fastest, simplest way to get connected as soon as you land. This guide explains the best eSIM options for USA travel, how to choose the right plan, network coverage realities (city vs national parks), and exactly how to set it up on iPhone and Android. Whether you’re in New York for a long weekend, driving the Pacific Coast Highway, or working remotely across time zones, you’ll find practical advice for smooth connectivity. We’ll also cover whether you need a US number, how much data you really need, and what to do if things don’t connect first time. If you’re comparing plans now, jump straight to our USA range on Esim United States, or browse every country on Destinations.Why use an eSIM for USA travel?Instant setup over Wi‑Fi—no physical SIM swap.Keep your home number active for calls/2FA via dual SIM.Avoid unpredictable roaming charges; pay a clear, local data rate.Flexible: 7/15/30‑day options, top‑ups, and multi‑country packs.Works on modern iPhones, Google Pixel, and many Samsung models.Pro tip: Install your eSIM profile before you fly (on Wi‑Fi), then activate data on arrival so your plan window starts when you actually need it.Quick picks: best eSIM options for USA tripsUse these scenarios to narrow your choice. Then compare plans on Esim United States.Best for short city breaks (3–7 days)Choose a 3–5 GB or 10 GB plan with 5G access.Prioritise strong urban coverage (T‑Mobile and AT&T are typically excellent in cities).Check if hotspot/tethering is included for sharing data to a laptop.Best for road trips and national parksPick a plan that supports both AT&T and T‑Mobile where possible, or one known for broad nationwide coverage.Expect patchy service in remote areas (e.g., parts of Yosemite, Yellowstone, deserts). Download offline maps ahead of time.A 15–30 GB plan is sensible for navigation, music, and occasional video.Best for heavy data users and hotspotLook for “unlimited” plans with clear Fair Use Policies (FUP). Many cap high‑speed data per day (e.g., 2–5 GB) before throttling.If you hotspot regularly, confirm hotspot allowance; not all “unlimited” plans allow tethering at full speed.Best if you need a US numberMost travel eSIMs are data‑only. If you need a local number (for reservations, ride‑hailing verification), choose a plan that explicitly includes voice/SMS.Alternatively, use your home number over Wi‑Fi Calling, or use apps like WhatsApp/Telegram for messaging.Best for multi‑country tripsFor Canada+USA+Mexico, consider a regional option on Esim North America.Continuing to Europe after the USA? A regional pack on Esim Western Europe simplifies cross‑border travel. You can also pick specific countries like Esim France, Esim Italy, or Esim Spain if your route is fixed.Coverage and performance in the US: what to expectNetworks: The “Big 3” are AT&T, T‑Mobile, and Verizon. Most travel eSIMs use AT&T and/or T‑Mobile. Some plans can switch networks automatically based on signal.Cities and suburbs: 5G is widespread, with excellent performance from AT&T and T‑Mobile.Rural and national parks: Coverage varies. Verizon is often strongest in remote zones, but many travel eSIMs won’t use Verizon. Don’t rely on continuous data during long stretches in the mountains or deserts.Speed management: Many eSIM plans are subject to “deprioritisation” at busy times, meaning locals may get priority in congested cells. This is normal and short‑lived.Hotspot: Allowed on many plans, sometimes with limits. Check the plan’s hotspot policy before purchase.Pro tip: If your eSIM supports manual network selection, try switching between AT&T and T‑Mobile in rural areas to find a workable signal.How to set up your USA eSIM (step‑by‑step)You’ll receive either a QR code or a manual activation code after purchase. Install on Wi‑Fi.Before you fly (checklist)Confirm your phone supports eSIM and is carrier‑unlocked.Buy your plan and keep the QR/manual code handy.Install the eSIM profile on Wi‑Fi, but do not enable mobile data until landing if your plan starts on first connection.Download offline maps for your route/parks.Turn on Wi‑Fi Calling on your primary line if you plan to use your home number over data.iPhone (iOS 17/18)Settings > Mobile Service (or Cellular) > Add eSIM.Scan the QR code or choose “Use Activation Code” and paste the code.Label it “USA eSIM”.Set Default Line: keep your primary for calls/SMS if you like; set USA eSIM as “Mobile Data”.Under Mobile Data, toggle “Allow Mobile Data Switching” off if you want to force data via the USA eSIM only.On landing, enable the USA eSIM line and Mobile Data. Ensure Data Roaming is on for the eSIM line.Android (Pixel/Samsung)Settings > Network & Internet > SIMs (names vary).Add eSIM > Scan QR or “Enter code manually”.Name it “USA eSIM”.Set “Mobile data” to USA eSIM; keep your primary SIM for calls if needed.Enable Data Roaming for the eSIM line on arrival.On arrival: connect cleanlyTurn off data roaming on your home SIM to avoid accidental roaming.Turn on only the USA eSIM for data.If no data, toggle Airplane mode for 10 seconds, then back on. Try a manual network scan.Troubleshooting quick fixesAPN: Some plans require a custom APN. Check your plan instructions and add the APN under Mobile Network settings.5G not available: Switch to 4G/LTE; some areas are LTE‑only or 5G is restricted on roaming profiles.No service: Manually select AT&T or T‑Mobile. Reboot if needed.Still stuck: Reinstall the eSIM profile only if advised by support. Contact support via chat/email (note time zones).How much data do you need?Light user (messaging, maps, email): 3–5 GB/week.Typical city tourist (socials, ride‑hailing, light video): 5–10 GB/week.Road‑tripper (navigation, streaming music, photos backup): 10–20 GB for 2 weeks.Remote worker (video calls, hotspot): 20–40 GB/month or an unlimited plan with clear FUP.Pro tip: Autoplay on socials and cloud photo backups burn data. Disable video autoplay and set photos to “Wi‑Fi only” backup to stretch your allowance.Cost and plan features to compareWhen comparing eSIM USA travel plans, look beyond data size.Validity and start rules: Does the plan start on first connection or date of purchase?Network access: AT&T, T‑Mobile, or both; 5G access included?Fair Use Policy: Daily high‑speed caps on “unlimited”; throttled speeds after cap?Hotspot/tethering: Allowed, and at what speeds?Top‑ups: Can you add more data without reinstalling a new eSIM?Support hours: Live chat/email availability in your travel time zone.Refund policy: Refund if you haven’t activated and there’s a compatibility issue.Number: Data‑only vs plans including a US number (voice/SMS).Device limits: Some plans restrict installation to one device; eSIMs can’t be “moved” once installed.Compare current options on Esim United States, or explore regional bundles on Esim North America.Planning multi‑stop trips?If you’re visiting multiple countries, regional eSIMs reduce admin and avoid mid‑trip SIM swaps.North America loop (USA, Canada, Mexico): choose Esim North America.Transatlantic holiday: pair your US plan with Esim Western Europe for onward travel.City‑hopping in Europe: individual country packs like Esim France, Esim Italy, and Esim Spain often deliver higher data per country at sharper pricing.Browse every country and region on Destinations.Business and group travellersBusiness teams: Centralise spend and manage multiple lines with pooled data and consolidated billing. See For Business.Tour leaders and creators: If you’re provisioning connectivity for clients or audiences, explore revenue‑share and co‑branding via our Partner Hub.At a glance: USA eSIM options (product snapshot)What we like - Fast, self‑serve activation and immediate connectivity on landing. - Competitive 5G data packs with clear validity. - Options for both city breaks and long road trips; some plans support multi‑network access.Considerations - Data‑only plans won’t give you a US phone number; pick a voice‑enabled plan if needed. - Rural coverage is inherently variable; download offline maps and expect dead zones in parks. - “Unlimited” usually has a daily high‑speed cap—check each plan’s FUP.Compare and buy on Esim United States.FAQs1) Will my phone work with a USA eSIM? - iPhone XR/XS and newer support eSIM; US iPhone 14/15 models are eSIM‑only. Most Google Pixel 4+ and Samsung Galaxy S20/S21/S22/S23/S24 variants support eSIM. Your device must be carrier‑unlocked. Check your exact model’s eSIM support before purchase.2) Do I get a US phone number with an eSIM? - Many travel eSIMs are data‑only, so no local number. If you need one, choose a plan that explicitly includes voice/SMS, or use your home number via Wi‑Fi Calling. Apps such as WhatsApp/iMessage work over data without a US number.3) When should I activate my plan? - Install the eSIM profile on Wi‑Fi before you fly. If your plan starts on first network connection, enable mobile data only once you land in the USA.4) Will it work in national parks and rural areas? - Coverage can be limited. AT&T and T‑Mobile are strong across most highways and towns, but expect dead zones in mountains, canyons, and deserts. Download offline maps and don’t rely on constant connectivity.5) Can I keep my WhatsApp and iMessage? - Yes. These apps tie to your existing number/account and will continue working over the eSIM’s data. Keep your primary SIM active (with data roaming off) to receive calls/SMS if needed.6) Is tethering allowed? - Often yes, but it’s plan‑specific. Some “unlimited” offers limit hotspot speeds or daily high‑speed amounts. Check the plan details before purchase.The bottom lineFor most travellers, an eSIM is the most convenient and cost‑effective way to stay connected in the USA. Choose your plan based on trip length, expected data use, and where you’ll be—cities vs road‑tripping through parks. Install before you fly, activate on landing, and keep your home number for calls and 2FA via dual SIM.Next step: Compare plans and get connected in minutes on Esim United States.

It’s not a brochure; it’s a decision aid. Start with a single, focussed conversion goal (buy, activate, or learn how eSIM works), and avoid sending travellers elsewhere until they’ve taken that action.Essential sections (checklist)Above‑the‑fold value prop: “Travel data that works on arrival — no SIM swap.”Primary CTA: “Get an eSIM” or “Choose your destination.” Secondary “How it works.”Social proof: ratings, partner trust marks, concise testimonials.Country/region picker with best‑selling packs (e.g., Esim Spain, Esim Italy, Esim North America).3‑step “How it works” with icons: Buy → Scan QR → Connect on landing.Clear inclusions: data allowance, validity, tethering, coverage, top‑up.Price clarity: local currency where relevant, taxes/fees if applicable.Compatibility check: iOS/Android models and dual‑SIM note.Support and refunds policy summary; link to full help.FAQ drop‑downs (top 5 only to keep it scannable).Pro tip: Embed a destination smart search tied to our catalogue so travellers can jump straight to Destinations.Traveller‑first template blocks you can copyHeadline options: - “eSIM for effortless travel data — no queues, no plastic.” - “Land connected in the USA/Europe — install your eSIM before you fly.”Lead paragraph: - “Skip airport SIM stalls. Buy your eSIM in minutes, install via QR, and connect instantly on arrival. Keep your usual number active for calls while using local data.”Feature bullets: - “Fast 4G/5G where available” - “Keep your SIM — no swap needed” - “Works in X countries” (adapt per plan) - “Hotspot/tethering supported” - “Secure checkout, instant delivery”Plan grid microcopy: - “Good for maps and messaging (3–5 days city break)” - “Great for streaming and hotspots (10–14 days+)”Destinations module: - “Popular now: Esim United States, Esim France, Esim Western Europe”UX patterns that boost conversionKeep plan cards consistent: allowance, validity, price, CTA in the same order.Add sticky CTA on mobile.Use device‑aware badges: “Works on your iPhone 13” where possible.Offer a “First time using eSIM?” link to a simple explainer rather than a long tech page.Ad copy templates that convertYour job: speak to the trip and the pain you remove (roaming shock, airport queues, public Wi‑Fi).

Use one UTM taxonomy across all channels and partners so your analytics platform tells a single story.Standard taxonomy (recommended)utm_source: partner or platformExample: “google”, “facebook”, “ota‑brand”utm_medium: channel“cpc”, “display”, “email”, “affiliate”utm_campaign: offer context“esim‑usa‑2025q1”, “esim‑western‑europe‑summer”utm_content: creative or placement variant“vid‑15s‑stories”, “img‑1080‑citybreak”, “lp‑variant‑a”utm_term: paid search keyword (where relevant)Naming rules: - Lowercase only, hyphens as separators, no spaces, no PII. - Keep to < 50 characters where possible. - Include date or season if you’ll revisit later.Set‑up steps (How‑To)1) Create a shared UTM guide - One page listing approved values and examples. - Store it alongside briefs on your internal drive or the Partner Hub.2) Build links with checks - Use a sheet with data validation or your BI tool’s URL builder. - Force required fields; block free‑text where possible.3) Map to analytics - In GA4, define channel groupings aligned to utm_medium. - Create campaign naming rules to auto‑group reports.4) QA before launch - Test each ad link in a clean browser session. - Confirm UTMs persist through any redirects. - Validate final landing URLs resolve correctly.5) Monitor and tidy - Weekly: flag off‑taxonomy values and correct them at source. - Archive ended campaigns to preserve CTR/CVR baselines.QA checklist: - Are all links HTTPS and canonicalised? - Are UTMs present on all paid links and CRM CTAs? - Is there a single default landing page per campaign? - Does your order confirmation page pass source/medium to revenue?Pro tip: If you’re driving to multiple country pages (e.g., Esim France and Esim North America), keep campaign consistent and vary utm_content to identify which destination module was clicked.Creative specs and file guidanceBrief clearly to avoid rework and keep load times fast.Static image (Social/Display)1080×1080, 1080×1350, 1200×628PNG/JPG, ≤ 500 KB (aim for 200–300 KB)Safe‑area for text: < 20% coverage for readabilityVertical video (Stories/Reels/TikTok)1080×1920, 9:16, 15–30 sMP4/H.264, ≤ 15 MB where possibleHook in first 2 seconds; show install flowHorizontal video (YouTube/Pre‑roll)1920×1080, 16:9, 15 or 30 sInclude brand bumper in first/last 1.5 sHTML5 display300×250, 728×90, 160×600, 300×600, 320×50Under 150 KB per creativeLanding page assetsHero image < 200 KB; lazy‑load non‑critical imagesSVG for logos/icons; system fonts or preloaded web fontsCopy guardrails: - Avoid vague superlatives; favour concrete benefits (e.g., “Install before you fly”). - Localise price and spelling (US vs UK English when relevant). - Make inclusions/exclusions explicit near the CTA.Case snapshotsAirline pre‑departure emailAudience: USA‑bound leisure travellersTactic: “Add eSIM before you fly” segment + Esim United States landingResult: +31% CTR vs generic roaming tips; 22% of clicks installed within 24 hoursOTA booking confirmation pageAudience: Weekend city‑breakersTactic: Inline module featuring Esim Spain and Esim ItalyResult: CVR uplift from 2.4% to 4.1% with localised imagery and pricesFintech travel card appAudience: Multi‑country travellersTactic: In‑app banner to Esim Western EuropeResult: 18% attach rate when shown post‑FX notificationPublisher travel guideAudience: France itinerary researchersTactic: Content block linking to Esim France with step‑by‑step installResult: Average time on page +42%; strong assisted conversionsLaunch in one week: a simple planDay 1: Scope and assign - Choose priority destinations via Destinations and set one goal (sales or installs). - Confirm analytics owner and paid media owner.Day 2: Landing page build - Implement the template blocks above; add country modules. - Set up events and test UTMs.Day 3: Creative and copy - Produce two image variants and one 15 s vertical video per destination. - Draft search, social, and CRM copy using templates.Day 4: Tracking and QA - Finalise UTM list, build links, and run full link tests. - Check mobile speed (aim < 2.5 s LCP).Day 5: Soft launch - Launch in one market (e.g., Esim North America) with 50% budget. - Monitor CTR, CVR, CPI; fix any leaks.Day 6–7: Scale and optimise - Roll out to additional pages (e.g., Esim United States, Esim France). - A/B headline and hero; shift spend to best‑performing placements.Download the co‑marketing asset packTo make this painless, grab the partner asset pack on our Partner Hub. It includes: - Editable landing page blocks (copy + wireframe) - Ad copy bank for Search, Social, CRM - UTM builder spreadsheet with validation - Brand guidelines, logos, and icon set - Creative spec checklist and QA worksheetIf you’re weighing a broader programme, see options on For Business.FAQ1) What’s the fastest way to go live? - Start with one destination page (e.g., Esim United States), one search campaign, and one social placement. Use the UTM sheet to keep tracking clean, then scale.2) Should we drive to a regional or country page? - If the itinerary is fixed, use country pages like Esim France. For multi‑stop trips, regional pages such as Esim Western Europe convert well.3) How do we explain eSIM to first‑timers without hurting conversion? - Keep it to three steps above the fold and put deeper guidance behind an expandable “How it works.” Avoid technical jargon on the primary path.4) How many ad variants should we run at launch? - Two image variants, one short video, and two copy angles per channel is enough to find a winner without spreading budget too thin.5) What metrics matter most in week one? - Landing page CVR, cost per install (or sale), and bounce rate by device. Use UTMs to break down performance by creative and destination.6) Can we cross‑sell during or after purchase? - Yes. In confirmation pages or post‑purchase emails, promote add‑ons like regional upgrades (e.g., Esim North America) or destination alternatives via Destinations.Next step: Download the asset pack and start your build on the Partner Hub.
