If you're traveling and wondering which countries offer free roaming, the short answer is: it depends on where you're going. With a Spanish mobile plan, you can use your data at no extra cost within the European Union and the European Economic Area, but outside that zone, things change completely. In this guide, we explain what free roaming means, where it truly applies, its limitations, and what to do when traveling to a destination not covered by the agreement.
What "free roaming" means
The term "free roaming" is used a lot, but it's important to understand what's behind it. Roaming is the service that allows your mobile phone to continue working when you leave your country and connect to a foreign operator's network. When we say "free," it actually doesn't mean it's literally free of charge, but rather that you don't pay an additional surcharge on top of what you already pay for your national plan.
This means you make calls, send messages, and browse using your regular allowance, just as if you were at home. This only happens in a specific list of countries thanks to a regulatory agreement. In the rest of the world, the operator can charge you per minute, per message, and per megabyte rates that quickly add up. That's why the key question isn't just "is there roaming?", but "is it included in my plan?". If you want to understand the concept in depth, we have a complete guide on what roaming is and how it's billed.
The EU/EEA's "Roam Like At Home" roaming
Here's the good news for European travelers. Since 2017, the European principle "Roam Like At Home" has been in place, obliging operators not to apply surcharges for using mobile phones within the bloc. With a Spanish plan, your data, calls, and SMS are included in the 27 countries of the European Union plus three countries of the European Economic Area that join the agreement: Iceland, Norway, and Liechtenstein.
This means you can travel through destinations like France, Italy, Portugal, Germany, the Netherlands, Greece, Croatia, or Ireland using your usual allowance, without activating anything or paying extra. Consumption is deducted from your national plan. It is a right guaranteed by European regulations and has been extended over time, making it one of the great advantages of traveling within the continent.
Quick rule: if your destination is one of the 27 EU countries plus Iceland, Norway, or Liechtenstein, your Spanish plan works without surcharges. For everything else, assume that NO roaming is included until you check.
However, "roam like at home" doesn't mean "browse without any limits." And that's where the fine print, which we'll look at next, comes in.
Limits of free roaming in the EU
European free roaming is real, but it has a fair use policy (also called "reasonable use") designed to prevent abuse, such as contracting a plan in a cheap country for permanent use in another. These are the limits you should know:
- Data roaming cap: In many plans, especially those with unlimited or very large data allowances, the operator sets a maximum amount of gigabytes you can consume while roaming within the EU. This cap usually depends on the price of your plan, not your total allowance.
- Surcharges if you exceed the limit: Once the included roaming volume is used up, you can continue browsing, but the operator applies a small surcharge per extra gigabyte consumed.
- Permanent use outside your country: The agreement is intended for travel, not for living permanently in another country using a Spanish SIM. If you spend more time abroad than at home for several months, the operator may warn you and apply charges.
The key is that each operator defines its own caps within the European framework, so two plans at the same price can have different roaming limits. If you want to minimize surprises, we recommend reading our guide on how to avoid roaming and its unexpected charges.
Countries without free roaming
This is the part that causes the most surprises. There are countries that are geographically in Europe but are not part of the EU roaming agreement, so your Spanish plan does not work without surcharge there. Among the destinations where there is usually NO free roaming are:
- United Kingdom: After Brexit, it ceased to be part of the agreement. Each operator decides whether to include it or charge separately, so it must be checked on a case-by-case basis.
- Switzerland: It does not belong to the EU or the EEA for these purposes; it usually has its own rates.
- Andorra: Despite being between Spain and France, it is outside European roaming.
- Turkey: Straddling Europe and Asia, it is not part of the agreement.
- Other nearby countries: Monaco, Albania, Serbia, Montenegro, Bosnia, North Macedonia, Kosovo, Faroe Islands, and similar.
- Outside Europe: United States, Canada, Mexico, all of Asia (Japan, Thailand, China, India...), Latin America, Africa, and Oceania. Here, "naked" roaming can cost several euros per megabyte.
In these destinations, using your mobile with your home SIM without a specific plan from your operator can generate bills for hundreds of euros. To properly understand the difference between being inside or outside the European zone, our guide on internet without roaming and how to get it can help you.
Quick zone-by-zone table
To make it clear at a glance, this table summarizes what to do depending on the zone you travel to. It is an indicative reference: always confirm the conditions with your operator before you leave.
| Zone | Roaming included? | What to do |
|---|---|---|
| EU (the 27) | Yes, no surcharge | Use your normal plan; monitor the data roaming cap |
| Iceland, Norway, Liechtenstein | Yes, no surcharge | Same as in the EU; fair use policy applies |
| United Kingdom | Depends on the operator | Check if your plan includes it; if not, use an eSIM |
| Switzerland, Andorra, Turkey | No, unless special package | Purchase a destination travel eSIM |
| USA, Canada, Mexico | No | Travel eSIM before departure |
| Asia, Latin America, Africa, Oceania | No | Travel eSIM; avoid "naked" roaming |
How to check your plan's limit
Before traveling, it's advisable to know exactly how much data you can spend while roaming and at what point you'll be charged. These are the most reliable ways to find out your plan's real limit:
- Review your plan's terms and conditions: Look for the "roaming," "international roaming," or "EU usage" section on your operator's website or app. This will show the volume of data included for roaming, which is almost always different from your total allowance.
- Check the welcome SMS: When you cross the border, your operator sends you an automatic message with the applicable rates and often the usage limit. Do not delete it without reading it.
- Call customer service: Directly ask, "how many gigabytes do I have included for roaming in the EU and what happens if I exceed them?". Ask them to confirm it in writing if possible.
- Activate consumption alerts: Many operators allow you to set a roaming spending limit to avoid surprises.
Tip: write down your data roaming cap before your trip. This way you'll know if it's enough for your European destination or if it's better to supplement it with extra data from an eSIM.
If a physical card seems impractical for your travels, you might be interested in first understanding what an eSIM is and why it has become the preferred option for frequent travelers.
The alternative outside the EU: travel eSIM
When your destination is not covered by European free roaming, the most convenient and economical solution is a travel eSIM. This is a digital SIM that installs on your mobile without changing anything physical: you purchase a data plan for the country you're visiting and connect to a local network at a local price, without international roaming surcharges.
At PuraSim, you get coverage in 218 destinations, plans starting from $0.85, activation via QR in 1 minute, hotspot function to share data with other devices, and 24/7 Spanish support. All without roaming: you pay local data rates, not the exorbitant figures of traditional roaming. For European destinations beyond your cap, or for Switzerland, the UK, Turkey, the USA, or Asia, it's the easiest way to have internet as soon as you land.
If your next trip is within the continent, check out our 30-day Europe eSIM option, ideal for long stays or to supplement your Spanish plan's limit. And if you're ready, you can choose your eSIM by destination country.
Frequently asked questions
In which countries do I have free roaming with my Spanish plan?
In the 27 countries of the European Union plus Iceland, Norway, and Liechtenstein. In all of them, you use your data, calls, and SMS allowance without surcharge, subject to your operator's fair use policy.
Is free roaming truly unlimited?
Not entirely. Although you use your usual plan, operators apply a fair use policy with a data roaming cap. If you exceed it, you'll be charged a small surcharge per gigabyte. The limit depends on the price of your plan, so it's advisable to check it before traveling.
Do I have free roaming in the UK after Brexit?
It depends. The United Kingdom left the European agreement, so each operator decides whether to include it or charge separately. Check your terms and conditions; if it's not included, a travel eSIM is usually much cheaper than roaming.
What about Switzerland, Andorra, or Turkey?
They are not covered by European free roaming. Some operators offer special packages, but by default, you would pay roaming rates. The recommended option is a destination travel eSIM.
What happens if I use my phone in the US or Asia without a plan?
Using "naked" roaming outside Europe can cost several euros per megabyte and generate very high bills. The safest option is to disable data roaming and use a local eSIM purchased before departure.
Does the eSIM work on my phone?
Most recent mobile phones are compatible with eSIM (iPhone XS or later, Galaxy S20 or later, Pixel 3 or later, among many others). You can check this in your phone settings or consult our 24/7 Spanish support.
Conclusion
In summary: you have free roaming with your Spanish plan in the 27 EU countries plus Iceland, Norway, and Liechtenstein, always within your operator's fair use policy and data roaming cap. Outside that zone (United Kingdom, Switzerland, Andorra, Turkey, USA, Asia, and the rest of the world), there is no included roaming, and connecting without a plan can be very expensive. The simple solution for these destinations is a travel eSIM: local data, quick activation, and zero surprises on your bill.
Before your next trip, check your plan's limit, and if you're going outside the EU/EEA, prepare your connection in advance. Choose your PuraSim eSIM and travel connected from minute one. And if you want to consult the official regulations, here are the EU roaming rules.
