Spain eSIM & Mobile Internet Guide (2025): Tourist SIM vs eSIM, Speeds

30 Oct 2025

Staying connected in Spain is straightforward if you know your options. This guide breaks down eSIM vs tourist SIM, what speeds to expect in cities and coastal areas, and exactly how to get set up at Madrid (MAD) and Barcelona (BCN) airports. Spain’s networks are mature, 5G is widely available in major cities, and EU roaming rules are generous—but the Fair Use Policy (FUP) can still catch travellers out. If you want a fast, fuss‑free setup, an eSIM is usually quickest. If you prefer a local number and big domestic data bundles, a physical tourist SIM can still make sense.

Below you’ll find practical steps to buy and activate an eSIM, where to find SIMs at the airport, how speeds differ between city, coast and countryside, and when to choose a multi‑country plan for a wider European itinerary. You’ll also find pro tips, EU FUP essentials, and a concise FAQ to keep you moving.

Quick answer: eSIM vs Tourist SIM in Spain

eSIM (data‑only, digital)
Best for: instant setup, keeping your home number active, short trips, landing late when shops are closed.
Pros: buy before you fly, QR or in‑app install, no passport queues, tethering supported on most plans, easy top‑ups.
Cons: usually data‑only (use apps for calls/SMS), local voice number not included.
Tourist SIM (physical, prepaid)
Best for: travellers who need a Spanish mobile number or heavy domestic data with local call minutes.
Pros: often large data bundles, local calls included, works in any unlocked phone with a SIM tray.
Cons: need ID to register, airport pricing can be higher, shops can be busy/closed, swapping SIMs risks missing bank/SMS codes.

If you’ll visit neighbouring countries, consider a regional plan like Esim Western Europe. Heading to Italy or France on the same trip? See Esim Italy and Esim France.

Spain’s networks and real‑world speeds

Spain’s main networks are Movistar (Telefónica), Orange, Vodafone and Yoigo (MásMóvil). Coverage on 4G is extensive; 5G is widespread in cities and growing along popular coasts.

City vs coast vs countryside speeds

Major cities (Madrid, Barcelona, Valencia, Seville, Bilbao)
Expect 5G in busy areas with typical speeds of 150–400 Mbps; strong 4G where 5G drops, around 30–100 Mbps.
Indoor coverage is generally solid; stadiums and stations can congest at peak times.
Coasts and resorts (Costa del Sol, Costa Blanca, Costa Brava)
Good coverage, especially near towns and beaches. Daytime congestion can reduce speeds to 10–50 Mbps around popular beaches and promenades. Late evening speeds often improve.
Islands (Balearics: Mallorca, Ibiza; Canaries: Tenerife, Gran Canaria)
Tourist hubs have 4G/5G; peak‑season load can slow speeds to 10–40 Mbps at busy spots. Venture a few blocks inland for better performance.
Rural and mountains (Asturias, Pyrenees, interior)
Coverage is patchier. Expect 4G/3G with 5–25 Mbps in valleys, dropping to limited service in remote villages and hiking trails. Download maps offline if driving.

Pro tip: Speed varies more by location and time of day than by brand of SIM. If you have a dual‑SIM phone, keeping an eSIM plus your home SIM improves redundancy.

Buying an eSIM for Spain: step‑by‑step

Choose your plan: Pick your data allowance and validity on Esim Spain. If you’ll cross borders, select Esim Western Europe.
Check compatibility: Most recent iPhone, Google Pixel and Samsung flagships support eSIM. Confirm in your device settings.
Buy and receive: You’ll get a QR code or an in‑app activation link.
Install: - iOS: Settings > Mobile Data > Add eSIM > Use QR/activation code. - Android: Settings > Network & Internet > SIMs > Add eSIM.
Label your lines: Set your eSIM as “Data only” and keep your home SIM “Calls & SMS” if needed.
Data roaming: Turn Data Roaming ON for the eSIM profile (this is required for travel eSIMs to work in Spain).
APN: It usually sets automatically. If not, use the APN provided with your plan.
Test: Open a browser and a maps app after landing. If no data, toggle flight mode for 10 seconds and retry.

Pro tips: - Install over reliable Wi‑Fi before you fly. At the airport, public Wi‑Fi can be busy. - Keep your home SIM active for banking SMS. Set the eSIM as your default data line. - Hotspot/tethering is supported on most travel eSIMs—handy for laptops and tablets.

Buying a physical tourist SIM at the airport (MAD/BCN)

You can buy prepaid SIMs from major operators or resellers at both airports. Availability and hours change, so treat this as a field guide, not a guarantee.

Madrid–Barajas (MAD): what to expect

Where to look:
After customs in Arrivals at T1 and T4 you’ll usually find telecom or multi‑brand electronics shops, convenience/newsstands, and currency exchange counters that sell SIMs.
Signage may read “Telefonía/Telecom” or show operator logos (Orange, Vodafone, Movistar). If in doubt, ask any information desk for “prepaid SIM.”
Typical steps: 1. Have your passport ready (ID is mandatory for SIM registration in Spain). 2. Choose a plan—ask about data allowance, EU roaming, and whether tethering is included. 3. Staff can fit the SIM and do a quick activation test.
Hours and pricing:
Common opening hours are roughly 08:00–22:00; late‑night arrivals may find shutters down.
Expect roughly €10–€35 for light data (10–30 GB) and more for larger tourist bundles. Airport prices can be higher than in the city.
If shops are closed:
Use airport Wi‑Fi to activate an eSIM in minutes via Esim Spain.

Barcelona–El Prat (BCN): T1 and T2

Where to look:
In T1 Arrivals, look for operator kiosks, electronics/accessory stores and newsstands that carry SIMs. T2 has fewer options; you may need to buy in the city if queues are long.
Typical steps: 1. Present your passport for registration. 2. Confirm EU roaming terms if you’re visiting other EU countries. 3. Ask staff to test data before you leave the counter.
Hours and pricing:
Daytime coverage is good; late evenings vary. Budget similar pricing to Madrid.

What you’ll need and how activation works

Passport: Spain requires ID to register prepaid SIMs.
Unlocked phone: Check before travelling.
Activation: Usually live within minutes; occasionally up to an hour.
Top‑ups: Can be done online, via operator apps, or at supermarkets and kiosks. Ask for help setting an English‑language app at the counter.
APN and settings: Typically automatic; staff can assist if data doesn’t start.

Pro tips: - Queue buster: If you see long lines or limited stock, switch to eSIM on the spot using airport Wi‑Fi. - Keep your home SIM: Dual‑SIM phones let you keep banking SMS and your usual number active. - Save receipts and plan details in your notes in case you need support.

EU roaming and FUP: what travellers need to know

Spain participates in the EU “Roam Like At Home” scheme, but Fair Use Policy (FUP) limits can apply:

Spanish tourist SIMs:
Domestic allowance (e.g., 100 GB) is often larger than your EU roaming allowance. While roaming in other EU/EEA countries, expect a lower cap—commonly 5–30 GB depending on the price of the plan.
Exceeding the FUP may result in a small surcharge per GB or throttled speeds until renewal.
Some budget sub‑brands exclude EU roaming—always check.
Travel eSIMs:
Country‑specific eSIMs typically work in Spain only.
Regional eSIMs (e.g., Esim Western Europe) include multiple countries with one allowance, avoiding per‑operator FUP surprises across borders.

Clear actions: - If you’re only in Spain, a local eSIM or tourist SIM is fine. - If you’re visiting multiple countries, use a regional eSIM to avoid variable FUP rules.

Coverage in popular destinations

Madrid: Excellent 5G across central districts (Sol, Salamanca, Chamartín). Expect 200–400 Mbps on 5G in open areas; 4G remains strong on the Metro and indoors.
Barcelona: Strong 5G around Eixample, Gothic Quarter, and tech hubs. Beachfront areas can congest midday; speeds rebound at night.
Valencia and Seville: Robust 4G/5G across city centres; 50–200 Mbps common. Event days can strain cells near stadiums.
Malaga and Costa del Sol: Good coastal coverage. Tourist hotspots (Marbella, Torremolinos) see daytime slowdowns; move a block inland for better throughput.
Alicante and Costa Blanca: Similar to Costa del Sol. Good 4G; growing 5G in towns.
Balearics (Mallorca, Ibiza): Busy beach zones see variable speeds; towns and ports are faster.
Canary Islands: Tourist areas covered; rural interiors can dip to 3G in pockets—download offline maps and tickets.

Hotspot, voice and apps

Tethering: Allowed on most eSIM and tourist SIM plans. Check your plan details.
Voice calls: Data‑only eSIMs don’t include a Spanish number; use WhatsApp, FaceTime, Telegram or Zoom over data.
Two‑factor codes: Keep your home SIM active for SMS from banks and services (set it as “Calls & SMS” only).

FAQ

Do I need a passport to buy a SIM in Spain?
Yes. Prepaid SIM registration is mandatory. Have your passport ready at airport shops and high‑street stores.
Is 5G worth it in Spain?
In cities, yes—latency and speeds are notably better. On the coast or islands at peak times, 5G can still congest, but it generally outperforms 4G.
Will my WhatsApp number change with an eSIM?
No. WhatsApp stays linked to your existing number. A data‑only eSIM gives you data while you keep your home number for apps and SMS.
Can I use hotspot/tethering?
Generally yes, on both eSIMs and tourist SIMs. It’s useful for laptops and tablets. Heavy tethering can drain your battery—carry a power bank.
How do I check my data balance?
For tourist SIMs, use the operator’s app or dial the USSD shown on the pack. For travel eSIMs, check your Simology account/confirmation email for the balance method.
What if I land late and shops are closed?
Activate an eSIM over airport Wi‑Fi in minutes via Esim Spain. It’s the fastest way to get online after hours.

Next step: Get connected in minutes with an Esim Spain plan tailored to your trip.

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.

APN, IMS & Carrier Services: The Hidden Settings That Control Your Data

A reliable mobile connection abroad depends on more than just signal bars. Three low‑visibility pieces of your phone’s setup do most of the heavy lifting: APN (Access Point Name), IMS (IP Multimedia Subsystem) registration, and Carrier Services (or carrier settings). Get these right and data, VoLTE calls, SMS/MMS and Wi‑Fi Calling tend to “just work”. Get them wrong, and you’ll see symptoms like “connected but no internet”, calls dropping to 3G (or failing entirely in 3G‑sunset countries), delayed messages or stubborn roaming issues. This guide translates the jargon, shows you exactly where to find the settings on iOS and Android, and explains when to reset versus edit—especially crucial if you’re travelling with an eSIM.If you’re planning trips to the US, Europe or beyond, you’ll also find links to ready‑to‑use regional eSIM options such as Esim United States, Esim North America and Esim Western Europe. Keep this page handy for quick fixes on the road.Quick definitions (plain English)APN (Access Point Name): The gateway settings your phone uses to reach the mobile data network. It includes the APN name, username/password if needed, and optional fields for MMS. Think of it as the Wi‑Fi password equivalent for mobile data.IMS (IP Multimedia Subsystem): The system carriers use to deliver modern voice and messaging over 4G/5G. If “IMS registration” is shown as “Registered”, your device can use VoLTE, SMS over IMS and Wi‑Fi Calling (subject to your carrier plan and device support).Carrier Services / Carrier Settings: On Android, “Carrier Services” is a Google app that provides up‑to‑date carrier configuration for things like RCS/IMS. On iPhone, “Carrier Settings” is a carrier bundle that tells iOS how to behave on a given network.Pro tip: APNs get you on the internet; IMS keeps modern calls and texts working over 4G/5G; Carrier Services/Settings glue it all together.What is APN IMS registration and why travellers should careIf you’ve searched “what is apn ims registration”, here’s the punchline: APN controls your data path; IMS registration confirms your phone is authorised to use IP‑based services like VoLTE and Wi‑Fi Calling. Travellers especially notice IMS after 3G shutdowns. In the United States, for example, carriers have retired 3G. Without IMS/VoLTE, voice calls may fail entirely or fall back to legacy tech that no longer exists. The right eSIM plus correct APN and a healthy IMS registration equals smooth sailing.Where to find these settings: iOS and AndroidiPhone (iOS)Check carrier settings version and update: 1. Settings > General > About. 2. If a “Carrier Settings Update” prompt appears, tap Update.View or edit APN (only if your carrier allows it):Settings > Mobile Data > Mobile Data Options > Mobile Data Network.If you don’t see “Mobile Data Network”, your carrier locks APN edits (normal for many profiles and eSIMs).Check VoLTE/Wi‑Fi Calling toggles:Settings > Mobile Data > Mobile Data Options > Voice & Data > ensure LTE/4G/5G is on and VoLTE enabled (label varies by iOS version).Settings > Phone > Wi‑Fi Calling > turn on if your plan supports it.Reset network settings (broad fix):Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.Pro tips: - On iOS, you often shouldn’t manually change APN; the carrier bundle sets it. If data breaks right after installing a new eSIM, remove and re‑add the eSIM before editing APN. - If roaming, enable Settings > Mobile Data > Data Roaming.Android (varies by brand, similar paths)Update Carrier Services:Open Google Play Store > search “Carrier Services” > Update.Or Settings > Apps > Carrier Services > Storage & cache > Clear storage, then Update via Play Store.Check IMS registration status:Settings > About phone > SIM status (or Status) > IMS registration status = Registered is ideal.On some Samsung models: Settings > Connections > Mobile networks > Network operators and Voice networks; or service menu codes (advanced; use with caution).View/edit APN: 1. Settings > Network & internet (or Connections) > Mobile network > Access Point Names. 2. Select the eSIM/line if prompted. 3. Choose the correct APN or tap + to add one from your provider’s instructions.Reset APN to default:APN screen > three‑dot menu > Reset to default.Reset network settings:Settings > System > Reset options > Reset Wi‑Fi, mobile & Bluetooth.Pro tips: - Keep “Preferred network type” on 4G/5G Auto. Turning off 4G/VoLTE can break calling in 3G‑sunset regions. - If you changed Private DNS, set it to Automatic while troubleshooting.When to reset vs edit: a practical decision guideUse this simple flow when something breaks after installing a SIM/eSIM or when roaming:Symptoms: “Connected without internet” or pages time outFirst: Toggle Airplane mode off/on; reboot phone.Then: Check data roaming is ON (when abroad).Next: Confirm the APN selected matches the profile provided by your eSIM provider.If APN fields look wrong/missing: Edit or add the APN per the provider’s exact instructions.Still failing: Reset APN to default (Android) or remove/re‑add eSIM (iOS/Android).Last resort: Reset Network Settings.Symptoms: Calls failing, or no VoLTE/Wi‑Fi CallingCheck IMS registration (Android) and VoLTE/Wi‑Fi Calling toggles.Update Carrier Services (Android) or Carrier Settings (iOS).If you’re in the US, ensure your device model is VoLTE‑compatible with local networks. Consider a data‑only plan and calling apps if not. See Esim United States.Symptoms: SMS/MMS delayed or failingEnsure mobile data is enabled (MMS often needs data).Verify APN “MMS” fields are present if your provider requires them.Update Carrier Services; clear its storage and re‑open Messages (Android).Golden rules: - Edit APN only if you have exact values from a trusted source (your carrier or eSIM provider). - Prefer “Reset APN to default” over random tweaks. - Avoid third‑party APN profiles from unverified websites.How APN and IMS affect VoLTE, Wi‑Fi Calling and roamingVoLTE (Voice over LTE): Requires IMS registration and carrier/device support. Without IMS in 3G‑sunset regions (e.g., the US), calls may not connect at all. For trips that include the US or Canada, see Esim North America.Wi‑Fi Calling: Also rides on IMS. Helpful indoors or in rural areas. Must be enabled on your device and provisioned by the carrier.SMS over IMS: Modern networks route texts over LTE/5G via IMS. If IMS registration flips to “Not Registered”, texts may delay or revert to older paths, sometimes failing on data‑only profiles.MMS: Often relies on correct APN “MMS” fields and mobile data. Some eSIM data plans do not support MMS on the data line; use chat apps if needed.Roaming: The APN set by your eSIM should generally work across partner networks. If you switch networks manually, keep APN unchanged unless told otherwise.Traveller tip: - For European trips that hop across borders without fuss, regional plans like Esim Western Europe are designed to “auto‑roam” with the right APN pre‑loaded. Country‑specific options include Esim France, Esim Spain and Esim Italy.Troubleshooting checklist (save for the road)Confirm your plan is active and has data balance.Ensure the correct line/eSIM is set for Mobile Data and Calls (dual‑SIM phones).Turn Data Roaming on when abroad.Preferred network mode: 4G/5G Auto.APN: Select the profile provided by your carrier/eSIM. If missing, add it exactly as given.Toggle Airplane mode off/on; then reboot.Update Carrier Services (Android) or accept Carrier Settings Update (iOS).Check IMS registration status (Android). If “Not registered”, ensure VoLTE is enabled and try a different local network if allowed.Clear Carrier Services storage (Android) and reopen your messaging app if RCS/SMS is flaky.Remove and re‑add the eSIM profile if issues began right after installation.Reset APN to default (Android), then re‑select the correct APN.Reset Network Settings as a last resort.Pro tip: - Keep a screenshot of working APN fields before experimenting. It makes recovery painless.Planning connectivity by destinationPick an eSIM that already includes correct APN and roaming parameters to minimise manual fixes: - Browse country and regional options on Destinations. - North America trips: Esim North America or the US‑specific Esim United States. - Western Europe touring: Esim Western Europe or country‑specific choices such as Esim France, Esim Spain and Esim Italy.For teams on the move, centralise setup guidance and support via For Business.

Update Carrier Services (Android), ensure VoLTE is on, reboot, and try another partner network if available. Some data‑only plans won’t register IMS for voice features.Will changing my APN affect VoLTE?Indirectly. A wrong APN can block data paths needed for IMS/RCS features. Use only the APN provided by your carrier/eSIM. Avoid editing the “APN type” to include “ims”; that entry is typically system‑managed.Where do I find APN on iPhone? I can’t see the fields.Many carriers lock APN editing on iOS. If Settings > Mobile Data > Mobile Data Options > Mobile Data Network isn’t visible, the carrier bundle manages it automatically. Remove/re‑add your eSIM or accept a Carrier Settings Update instead of editing.Should I reset network settings or just APN?Start with APN reset (Android) or re‑adding the eSIM. Only use full Network Settings reset if simpler steps fail—it will forget saved Wi‑Fi and Bluetooth pairings.Do I need Carrier Services on Android?Yes. It’s a Google component that updates carrier config for IMS/RCS. Keep it updated. If messages misbehave, clear its storage and relaunch your messages app.Why do calls fail in the US but data works?Likely a VoLTE/IMS issue on a 3G‑sunset network. Ensure VoLTE is on, IMS is registered, and your device is compatible. If not, use data‑based calling apps and pick a plan optimised for the region, such as Esim United States.The bottom lineAPN gets you online; IMS keeps VoLTE/SMS/Wi‑Fi Calling alive; Carrier Services/Settings keep both in sync.On iOS, avoid manual APN edits unless instructed. On Android, use “Reset to default” before entering trusted APN values.For travel, choose eSIMs with correct roaming profiles and keep VoLTE enabled—critical in 3G‑sunset countries.Next step: pick a region‑ready eSIM on Destinations and travel with confidence.
