Unlimited Data in Spain: Are These SIM & eSIM Plans Real?

Spain received over 94 million international visitors in 2025, and the number keeps climbing in 2026. With that kind of traffic, you’d expect the question of mobile connectivity to be a solved problem. It isn’t. Travellers keep arriving at Madrid-Barajas or Barcelona-El Prat, pick up a SIM card labelled “unlimited data,” then hit a throttle wall on day three of their trip. The confusion usually starts with two words on the packaging that mean very different things depending on whether you read the small print. This guide cuts through that, covering every major prepaid SIM and eSIM option available in Spain in 2026, what the data caps actually are, how EU roaming works, and how to activate a plan without standing helplessly in a phone shop for forty-five minutes.

What “Unlimited” Actually Means in Spain

Spanish telecoms use the word “ilimitado” — unlimited — with enthusiasm. What they almost never mean is genuinely uncapped, unthrottled data in perpetuity. In Spain’s prepaid market, “unlimited” typically means one of two things: either a very large but finite high-speed data allowance (say, 150 GB or 200 GB), after which speeds drop sharply, or a plan that is marketed as unlimited but carries a Fair Use Policy that defines a ceiling on full-speed usage.

Post-paid contracts from the big three operators — Movistar, Vodafone, and Orange — can come closer to genuinely unlimited, but prepaid plans, which are what almost every tourist or short-term visitor will buy, all have a throttle point. After you burn through the high-speed allowance, speeds typically drop to somewhere between 64 kbps and 128 kbps. That’s fast enough to receive WhatsApp text messages and just about load a basic webpage. Streaming video or uploading photos to the cloud becomes painful.

For most travellers — checking maps, booking restaurants, posting to Instagram, video calling home — even the throttled speed ceiling rarely gets hit. A 150 GB monthly allowance for a single person is a generous buffer. The problem comes when groups of travellers share a hotspot, or when someone is streaming Netflix in the hotel because they didn’t check whether the accommodation’s WiFi was any good. Know what you’re actually buying, and you’ll have zero surprises.

Movistar Prepaid and eSIM Plans — Coverage King with a Price to Match

Movistar, the Spanish arm of Telefónica, has the widest network coverage in Spain. If you’re heading beyond the major cities — into the Pyrenees, through the meseta of Castilla, or along the rural backroads of Extremadura — Movistar will almost always have signal where others don’t. That coverage advantage is real, and it comes with a corresponding price.

Their top prepaid tier in 2026, the Movistar Prepago Premium, offers between 150 GB and 200 GB of high-speed data per 28-day cycle. After that allowance is exhausted, speeds are throttled to 128 kbps. The plan includes unlimited national calls. SMS are charged at standard rates, typically €0.20–€0.30 per message, so WhatsApp is what everyone actually uses. The projected price for this plan is €30–€35 per 28 days.

Movistar offers eSIM for prepaid plans, which is good news for travellers who want to avoid fiddling with a physical SIM tray on a roaming device. The process is not fully digital yet for tourists. You’ll need to visit a physical Movistar store, register your passport, and the staff will provide a QR code to scan into your phone’s eSIM settings. The whole thing takes about fifteen minutes and works reliably. Attempting to do it online without a Spanish address and Spanish ID is more trouble than it’s worth.

Movistar’s app, Mi Movistar, is available on iOS and Google Play and handles top-ups, balance checks, and plan renewals cleanly. Their website for prepaid plans is movistar.es/particulares/movil/prepago/. Since 2024, Movistar has gradually increased data allowances without significant price increases, and eSIM activation has become noticeably smoother at their store level.

Vodafone Prepaid and eSIM Plans — Urban Performance and Competitive Data

Vodafone’s network in Spain punches above its weight in cities and densely populated areas. In Madrid, Barcelona, Seville, Valencia, and along the main tourist corridors of the Costa del Sol, Vodafone’s 5G coverage is solid. The drop-off in rural areas is more pronounced than with Movistar, but for a visitor spending most of their time in towns and cities, it’s rarely noticeable.

The Vodafone Prepago L plan — their headline prepaid option — offers approximately 120 GB to 180 GB of high-speed data per 28-day cycle. After the allowance runs out, speeds reduce to between 64 kbps and 128 kbps. Unlimited national calls are included. SMS carry standard rates similar to Movistar. Pricing lands at an estimated €25–€30 per 28 days, making it slightly cheaper than Movistar’s top tier for a comparable (if slightly lower) data cap.

Vodafone also supports eSIM for prepaid plans in 2026. The activation method mirrors Movistar’s approach — in-store visit, passport registration, QR code delivery. Since 2024, Vodafone has been rolling out improved prepaid eSIM processes, and their “Vodafone yu” sub-brand, which targets younger and more digitally-native users, sometimes offers slightly different prepaid bundles that lean heavier on data. Worth checking both when you visit a store.

The My Vodafone app (iOS and Google Play) manages everything: data monitoring, top-ups, and plan changes. The Vodafone prepaid website is vodafone.es/particulares/movil/prepago/. One practical note: Vodafone SIMs are also sold in some larger supermarkets, which can be convenient if no Vodafone store is nearby, though activation help is limited outside official stores.

Orange Prepaid and eSIM Plans — The Flexible Middle Ground

Orange occupies a comfortable middle position in Spain’s mobile market — competitive pricing, solid urban coverage, and a prepaid range that’s straightforward to navigate. Their primary prepaid line is branded as “Go” plans, and the top of that range is the Orange Go Max.

In 2026, the Orange Go Max offers an estimated 100 GB to 150 GB of high-speed data per 28-day cycle, with throttling applied after the allowance is consumed. Unlimited national calls are included. Pricing is estimated at €25–€30 per 28 days. The data cap sits lower than Movistar’s premium tier, but the price is comparable to Vodafone, making it a reasonable option for travellers who are primarily staying in cities where Orange’s signal performs well.

Orange supports eSIM for prepaid customers in 2026. As with the other operators, in-store purchase and activation is the most reliable path. Orange has invested in improving their digital activation processes since 2024, but the experience can vary by store location. Their authorized dealers, which often include electronics retailers, carry physical SIMs but may not be able to handle eSIM setup.

The My Orange app on iOS and Google Play handles balance monitoring, top-ups, and plan management. The Orange prepaid website is orange.es/tarifas/prepago. One genuine advantage of Orange is their retail footprint — authorized dealers are common in smaller towns, so finding a place to top up is rarely a problem even away from major cities.

Lycamobile — The Budget MVNO That Travellers Overlook

Lycamobile is a Mobile Virtual Network Operator, meaning it doesn’t own its own towers — it runs on Movistar’s infrastructure, giving it the same underlying coverage as Spain’s biggest network, at lower prices. It’s particularly popular with international travellers and expat communities because it consistently undercuts the major operators on price while offering generous data allowances and, unlike the big three, often includes unlimited national SMS in its top bundles.

The Lycamobile Spain National XL Plan (2026 projection) is their standout offering. It’s marketed as “unlimited” data, with a high Fair Use Policy cap typically in the range of 150 GB to 250 GB at full speed, after which speeds are throttled. The plan includes unlimited national calls and often unlimited national SMS — a small but useful difference from the major operators. Pricing sits at an estimated €20–€25 per 28 days, making it noticeably cheaper than the Movistar or Vodafone equivalents for comparable or greater data.

The trade-off with Lycamobile is the activation experience. Their website is lycamobile.es and their app — Lycamobile Spain — is on iOS and Google Play. Physical SIM cards are easy to find: they’re stocked in smaller convenience stores, kiosks, and tobacconists (estancos) across Spain, not just in dedicated phone shops. Activation, however, requires you to register your passport details either online or via a call to 2211 (free), and the process can occasionally be slower than walking into a Movistar store with a staff member to help.

eSIM availability from Lycamobile Spain remains less straightforward than the big three in 2026. It’s an area in active development, so check their website before assuming it’s available. If eSIM is a priority, the major operators are the safer choice.

For the step-by-step physical SIM activation: purchase the SIM, insert it, call 2211 or dial *139# and follow the prompts, then provide your passport number, name, and date of birth. Top up via the app or by dialing a shortcode, and activate your chosen bundle. The whole process typically takes under twenty minutes once the SIM is in your phone.

EU Roaming Rules in 2026 — What “Roam Like At Home” Actually Covers

If you buy a Spanish SIM and then travel from Spain into France, Portugal, Germany, or any other EU/EEA country during your trip, the “Roam Like At Home” regulation protects you. This rule — extended until 2032 — means you can use your Spanish prepaid plan’s calls, SMS, and data across all EU/EEA member states without paying extra roaming charges on top of your standard plan cost.

The nuance is in the data. Calls and SMS roam at domestic rates with no additional cap. Data, however, is subject to a Fair Use Policy to prevent operators from being undercut by people permanently living in other EU countries while using a cheap Spanish SIM. The minimum data allowance you must receive while roaming is calculated using this formula:

(Price of your plan in EUR ÷ Regulated wholesale data cap) × 2

In 2026, the regulated wholesale data cap is €1.55 per GB. This is down from €1.80/GB in 2024, and it continues dropping to €1.30/GB in 2027. The decreasing cap is good news for travellers — it means the roaming data minimum increases year on year. For a €30 plan in 2026: (30 ÷ 1.55) × 2 = approximately 38.7 GB of roaming data minimum. For a €25 plan: approximately 32.2 GB. For a €20 plan: approximately 25.8 GB.

Operators can choose to be more generous than this minimum, but not less. If you exceed your roaming data allowance, a surcharge applies — projected at approximately €0.002 per MB (€2 per GB) in 2026, decreasing from €0.0022/MB in 2024.

One point worth understanding: if you spend more than four consecutive months roaming outside Spain on a Spanish SIM, operators are entitled to apply surcharges or suspend service after a warning. For a short-term tourist this is irrelevant. For digital nomads bouncing between countries for months at a time, it’s a consideration.

Where to Buy Your SIM or eSIM in Spain

The airport is the first place most travellers see SIM options, and it’s genuinely convenient — but it comes with a premium. Kiosks at Madrid-Barajas, Barcelona-El Prat, Malaga-Costa del Sol, and most other major Spanish airports sell SIMs from the main operators. You’ll pay slightly more per plan than at a city-centre store, but if you land, need data immediately, and don’t want to hunt for a phone shop, it’s a workable option. Staff at airport kiosks can usually handle basic passport registration and activation.

Official operator stores — Movistar, Vodafone, or Orange branches — are the best option for tourists who want reliable activation, eSIM setup, or help with any configuration issues. Staff speak at least basic English in tourist-heavy areas, and the process is straightforward when you have your passport ready. In major cities, these stores are abundant. In smaller towns, check the operator’s store locator on their website before arriving.

Supermarkets and electronics stores — Carrefour, El Corte Inglés, Media Markt — carry physical SIM cards from multiple operators. These are fine for picking up a SIM, but activation help is minimal and eSIM setup is essentially unavailable. Lycamobile SIMs are widely sold in small convenience stores, tobacconists (estancos), and Chinese bazaars — the kind of shops you find on almost any Spanish high street.

Online purchase is not practical for most tourists. Spanish operator websites require a local address for delivery and ID verification that’s designed for residents, not visitors. Skip it.

Step-by-Step Activation — Physical SIM and eSIM

Physical SIM Activation

1. Purchase in-store. Hand over your passport and the store clerk will begin registration. This is legally required in Spain for all SIM purchases.
2. Registration takes 5–15 minutes. The clerk enters your details into the operator’s system. Be patient — it sometimes involves a brief identity check that goes through a central system.
3. Insert the SIM. Your phone may need to restart once the SIM is placed.
4. APN configuration. In most cases, your phone picks up the correct APN (Access Point Name) settings automatically. If mobile data doesn’t work within a few minutes, ask the clerk to set it manually, or find the correct APN settings on the operator’s website.
5. Test connectivity. Load a webpage or send a WhatsApp message. If it works, you’re live.
6. Download the app. Get Mi Movistar, My Vodafone, My Orange, or Lycamobile Spain from your app store and log in to monitor your usage.

eSIM Activation

1. Confirm your device is eSIM compatible. iPhone XS and later, recent Samsung Galaxy S and Fold series, and Google Pixel 3 and later all support eSIM. Check your phone’s settings under Mobile Data or Cellular to confirm.
2. Visit an official operator store. Bring your passport. Request an eSIM prepaid plan.
3. Complete registration. Same ID process as a physical SIM.
4. Receive QR code. The clerk provides a printed or on-screen QR code unique to your eSIM profile.
5. Scan in settings. On your phone: Settings → Mobile Data (or Cellular) → Add Data Plan (or Add eSIM) → scan the QR code.
6. Follow on-screen prompts. Your phone will download the eSIM profile. This takes about one minute with a WiFi connection.
7. Set as active line. If you have a dual-SIM phone, choose which line handles mobile data.

WiFi Across Spain — When You Can Rely on It and When You Can’t

WiFi in Spain is widespread enough that a tourist with a tight budget could theoretically survive on free networks alone — but the quality is inconsistent enough that this would be a frustrating strategy. Knowing where it works well, and where it doesn’t, helps you plan your data use more intelligently.

Airports across Spain offer free WiFi. Madrid-Barajas and Barcelona-El Prat both provide it with no time limit, though speeds slow noticeably during peak hours when the terminal is full of travellers doing exactly what you’re doing.

Renfe’s major train stations — Atocha in Madrid, Sants in Barcelona — offer free WiFi in the waiting areas. On the AVE and Avlo high-speed trains themselves, passengers get access to free WiFi through the PlayRenfe platform, which also includes on-demand entertainment. The train WiFi is adequate for messaging and browsing, though video streaming is inconsistent at speed through tunnels.

Hotels, hostels, and holiday rentals almost universally provide WiFi. Quality varies — a rural casa rural might give you a weak signal that drops on the floor above the router, while a modern city hotel will have enterprise-grade connectivity in every room. When quality matters, a personal SIM is your backup.

Cafes and bars with “WiFi gratis” signs are common in cities. Passwords are usually written on a chalkboard near the counter or printed on your receipt. This is fine for checking email over a coffee, but treat all public WiFi as insecure. Use a VPN — apps like ProtonVPN or Mullvad are worth having installed before you travel.

2026 Budget Reality — What You’ll Actually Pay

Here’s what Spanish prepaid SIM plans genuinely cost in 2026, broken down by travel style:

• Budget tier (light users): Lycamobile National XL at approximately €20–€25 per 28 days. You get 150–250 GB of high-speed data, unlimited calls, and often unlimited SMS. Best value for solo travellers on a tight budget who don’t need rural coverage.



• Mid-range tier (most travellers): Vodafone Prepago L or Orange Go Max at approximately €25–€30 per 28 days. Around 120–180 GB of high-speed data (Vodafone) or 100–150 GB (Orange), unlimited calls, good urban coverage. The sweet spot for the majority of visitors.
• Comfortable tier (heavy users or rural travel): Movistar Prepago Premium at approximately €30–€35 per 28 days. Up to 150–200 GB of high-speed data, widest coverage in Spain, reliable eSIM activation. Best for travellers venturing beyond tourist corridors or those who need the most consistent signal.

One-off costs to factor in: physical SIM cards are typically free or cost €1–€3. The plan itself is the main expense. Top-ups can be done in-store, via app, or at kiosks. Topping up at convenience stores is usually the same price as doing it online.

Common Mistakes Travellers Make with Spanish SIMs

Buying at the airport without comparing options. Airport kiosks are convenient, but the plans sold there are sometimes older configurations or priced a few euros higher than what you’d find at an official store in the city. If you can wait ninety minutes until you reach your accommodation area, you’ll likely get a better deal.

Assuming eSIM activation can be done entirely online. In 2026, most Spanish operators still require an in-store visit with a passport to activate an eSIM for prepaid plans. Travellers who arrive expecting to download a profile from an email are regularly disappointed. Plan for a store visit.

Forgetting to check APN settings after SIM insertion. If mobile data isn’t working within a few minutes of inserting a new SIM, APN settings are usually the culprit. Each operator’s APN details are on their website. This is a two-minute fix that many travellers spend an hour worrying about.

Not monitoring data consumption while hotspot sharing. Sharing a Spanish prepaid SIM’s hotspot with a group of four people watching YouTube is how you burn through 150 GB in three days. Download the operator’s app and check your balance daily if you’re sharing data.

Expecting full roaming data when travelling outside Spain. If you buy a Spanish SIM and then spend a week in Portugal or France, your roaming data is governed by the EU Fair Use Policy formula — not your full domestic allowance. For most plans this still gives you 25–38 GB of roaming data, which is generous, but it’s not the same as being at home.

Travelling with a SIM-locked phone. Some phones purchased on contract in other countries are locked to a specific network and won’t accept a Spanish SIM. Check that your phone is unlocked before you leave home. Your existing carrier can usually unlock it for free after a request, but it can take several days to process.

Frequently Asked Questions

Is there a genuinely unlimited prepaid SIM in Spain with no speed throttling?

Not in the prepaid market. All prepaid “unlimited” plans in Spain in 2026 have a high-speed data cap — typically 100 GB to 250 GB — after which speeds are throttled to 64–128 kbps. Genuinely unlimited, unthrottled data exists only on post-paid contracts, which require a Spanish address and bank account. For tourists, the high caps on prepaid plans are sufficient for almost all travel use cases.

Can I activate a Spanish eSIM before arriving in Spain?

Not reliably with the major operators (Movistar, Vodafone, Orange), which require in-person passport registration at a physical store. Lycamobile’s eSIM availability in Spain is still developing in 2026. If you want a pre-arrival eSIM, international travel eSIM providers like Airalo or Holafly offer Spain-specific plans that can be purchased and activated entirely online before departure, though these are typically more expensive per GB.

Which operator has the best coverage outside major Spanish cities?

Movistar has the widest rural and regional coverage in Spain, consistently outperforming Vodafone and Orange in less-populated areas. Since Lycamobile runs on Movistar’s infrastructure, it benefits from the same coverage at a lower price point. For trips involving rural Andalusia, inland Castile, the Pyrenees, or the Canary and Balearic Islands, Movistar or Lycamobile are the safer choices.

Do Spanish prepaid SIMs work in Portugal, France, and other EU countries?

Yes, under the EU “Roam Like At Home” regulation, extended until 2032. Calls and SMS roam at domestic rates. Data is subject to a Fair Use Policy: in 2026, the minimum roaming data is calculated as (plan price in EUR ÷ €1.55) × 2. A €25 plan gives at least 32.2 GB of EU roaming data at full speed. Beyond that, a surcharge of approximately €0.002 per MB applies.

What documents do I need to buy a SIM card in Spain?

Non-EU citizens need a valid passport. EU citizens can use their national identity card. Spanish law requires identity registration for all SIM purchases, so the document is mandatory — not optional. Keep your passport accessible during purchase. The registration process takes 5–15 minutes in-store and is straightforward with the right ID in hand.
