Internet in Spain if you are coming from abroad: what to know
Spain has one of the best networks in Europe. What your options are depending on where you are coming from, and what to do if your roaming does not cover the EU.

If you are coming from the European Union
You need nothing. Since 2017 the roam like at home principle applies: you use your home plan with no surcharge inside the EU, within the reasonable limits your contract sets. You land, the phone hooks on and you carry on browsing.
The only nuance is permanent use: the rule is designed for travelling, not for living all year in another country on your home line. For a holiday or a work trip it does not apply.
If you are coming from outside the European Union
Here you do have to decide, and that covers anyone arriving from the United Kingdom, the United States, Latin America or Asia. Your own operator's roaming can be expensive and it is worth checking before you board.
The three usual ways out: pay your plan's roaming, buy a Spanish SIM on arrival, or arrive with an eSIM already installed. The advantage of the last one is the same in Spain as anywhere, having data from the airport, and here that matters because the big airports are far from the centre and the transfer is organised from the phone.
What coverage is like by area
| Where | What to expect |
|---|---|
| Cities and coast | Wide 4G and 5G, no surprises |
| AVE and long-distance trains | Good overall, with breaks in tunnels |
| Inland villages | 4G almost always; gaps in valleys and mountains |
| Balearics and Canaries | City-level coverage in the tourist areas |
| Nature parks and mountains | Patchy; download the maps beforehand |
Public wi-fi is plentiful in hotels, cafes and on transport, but treat it as what it is: an open, shared network. For banking and purchases, mobile data is better.
Registering a local SIM
In Spain prepaid lines are registered with an identity document or passport too, so buying a local SIM means identifying yourself. It is done in any operator shop and in many tobacconists, but it is an errand and it costs you time on your first day.
What you will use
A trip around Spain draws mainly on maps and on looking for places to eat, which uses little. With wi-fi at your accommodation, the normal range is 200 to 500 MB a day.
If you want to refine the sum before choosing a plan, the figures by hour and by day are in how many gigabytes a trip really uses.
Frequently asked questions
Do I need an eSIM to travel to Spain from the European Union?
No. Inside the EU your home plan works with no surcharge thanks to the roam like at home principle. An eSIM makes sense if you are coming from outside the Union.
Is mobile coverage good in Spain?
Yes, one of the best in Europe: 4G across practically all inhabited territory and 5G in every provincial capital. The gaps are in the mountains and in some inland valleys.
Can I buy a prepaid SIM in Spain as a tourist?
Yes, in operator shops and in many tobacconists, but it has to be registered with a passport or identity document. It is a first-day errand that an eSIM avoids.
Does public wi-fi work in Spain?
There is plenty of it in hotels, cafes, airports and on transport. As with any open network, it is better not to use it for banking or purchases: for that, mobile data.
Will I have coverage on the AVE?
Generally yes, though there are breaks in tunnels and on some mountain sections. If you plan to work on the train, expect interruptions.
