Solution 1: Using your UK mobile plan in Spain
Most UK travellers naturally start here: can I just keep my normal mobile plan in Spain?
The good news is that Spain sits in the EU roaming zone for the four big UK networks, which means you usually get to use part of your monthly UK allowance — calls, texts and data — without extra charges, up to a fair usage cap.
The not-so-good news: fair usage caps and daily pass fees can still bite if you stay several weeks, run a hotspot for work, or stream a lot of video. So before you land in Barcelona or Seville, it’s worth knowing exactly what your network includes — and where the shortcode comparison below comes in.
UK operator roaming in Spain
Here’s what each of the four major UK operators offers for Spain:
EE places Spain in Zone 1 (Europe). Most modern Smart, Essential and Full Works plans include EU roaming, while older plans use the Roam Abroad Pass (around £2.47 per day) to unlock up to 50 GB of your UK allowance.
Three UK covers Spain via Go Roam in Europe: roaming included at no extra cost on most plans, with a 12 GB fair usage limit on Pay As You Go and Advanced plans.
Vodafone UK puts Spain in its Zone B (Europe). Newer Xtra plans include it for free, while older plans charge a daily fee of around £2 per day with a 25 GB cap before throttling kicks in.
O2 includes Spain in its Europe Zone, with most plans giving you your full UK allowance up to 25 GB before extra charges of around £3.50 per GB.

Are you wondering what you can do with 1 GB of data? Here are some concrete examples:
- Listening to music on Spotify for 1 hour every day will last you 20 days.
- Watching an HD video (1080p quality) for 30 minutes.
- Binge-watching 4K videos for 10 minutes.
- Video chatting for 4 hours on WhatsApp, or having fun on Insta and TikTok.
If you want to avoid unexpected charges, we have created a tool to calculate your roaming charges abroad. Feel free to try it out to see how quickly you use up your data!
Advantages:
For most UK travellers heading to Spain, this is the easiest option by far. You don’t need to buy anything, swap a SIM, or set up an eSIM — you just land and your phone works.
If your plan is on EE, Three, Vodafone or O2 and includes Spain in its EU roaming zone, you can use your UK calls, texts and data normally up to the fair usage cap. For a one or two-week holiday with moderate usage, that’s usually plenty.
You also keep your UK number live the whole time, which is handy if you’re expecting calls from work, family, or for two-factor authentication codes.
Disadvantages:
While roaming on your UK plan in Spain is very practical thanks to EU agreements, there are still a few downsides:
- Keep an Eye on Your Data: Be mindful of your data consumption, particularly with background apps. They can consume your allowance faster than you can enjoy sangria.
- Fair Usage Caps: Depending on your operator, your plan might feel a bit limiting. For instance, the 25 GB cap on Vodafone and O2 may be tight for heavy data users, whereas EE’s offer of up to 50 GB is quite generous for extended trips.
- Older plans, older rules: If you signed up before 2021, you may be on a plan that still charges a daily roaming fee (£2 to £2.50 per day). Worth checking in your operator’s app before you go.
- Internet Access: While it’s part of the package, your connection can be unpredictable depending on where you are. This isn’t ideal for live streaming from Seville!
Solution 2: Local SIM card in Spain
The second option is to get a local SIM card once you’re there. By choosing this route, you avoid roaming fees and enjoy local rates for mobile internet, which can make a real difference for longer stays.
In practice, you can find a card quite easily, whether at an airport, a telecom store, or in local sales points (and that’s part of the experience).
Which local mobile operator for a stay in Spain?
In Spain, the main mobile operators are Movistar, Vodafone Spain, and Orange Spain, alongside lower-cost MVNOs like Yoigo, Lowi, Simyo or Lebara. The idea is to compare the network coverage and mobile data allowance based on your route, and to check the validity period of the SIM card before you buy.
Once you’ve bought your local SIM card, simply insert it into your phone and follow the activation instructions. And just like that, you’re ready to explore Spain while staying connected like a local.

Advantages:
For longer stays or heavy data users, a local Spanish SIM card is often the most cost-effective option. Local tourist plans typically give you far more data per pound than UK roaming caps allow.
You also get full local rates for calls and texts inside Spain, which is useful if you’re booking accommodation, calling restaurants, or arranging activities on the ground.
Disadvantages:
Language Barrier and Technical Complexities
When purchasing, setting up, or even troubleshooting, you might feel lost with technical jargon, unless the shop’s English is up to it.
Device Incompatibility
First and foremost, make sure that your smartphone or 4G modem is unlocked and compatible with local frequencies. Also, pay attention to the SIM card size, which can vary and may not fit your phone.
Risks and Downsides
- Loss of Your UK Number: By replacing your SIM, you risk temporarily losing your regular number, which can be inconvenient if you’re expecting important calls or 2FA codes.
- Frequent SIM Changes: If your travels take you on to a neighbouring country, you might need to change SIM cards more than you’d like.
- Documentation requirements: Some Spanish operators ask for ID, a local address, or a minimum subscription duration — worth checking before you go.

Solution 3: Holafly eSIM for Spain
For us, there is a third solution: the Holafly eSIM for Spain. And here, we are clearly on the simplest option if you don’t want to hassle.
No store, no paperwork, no complicated handling. You activate your eSIM, and you’re connected.
In practice, it allows you to stay connected easily everywhere in Spain: receive booking confirmations from your hotel in Madrid, book a restaurant on your favorite app, or organise your visits without ever worrying about your connection (and that, while traveling, is a real comfort).
What is an eSIM?
An eSIM is simply a SIM card integrated directly into the phone. No need for a physical card, everything is done online in a few minutes.
And on top of that, you can have multiple eSIM profiles on your smartphone, which allows you to keep your UK number active while using local internet in Spain. So you don’t miss a call or a 2FA code from home.
Advantages:
The main advantage here is clearly peace of mind before departure. You download your eSIM calmly at home, either via the app or directly by email.
As a result: you arrive in Spain already ready to be connected. You can even activate your line just before boarding the plane or upon exiting the airport (and that makes all the difference when arriving in a country you don’t know).
Then, everything is much simpler: no paperwork, no store, no unpleasant surprises. You enjoy an immediate internet connection without constraints, whether in Barcelona, Seville, or elsewhere.
And on top of that, you keep your UK number active in parallel, while using the internet locally. In short, it’s a quick, efficient solution, and above all, hassle-free.
Disadvantages:
The main point to keep in mind is that the price can be higher than a local SIM card, especially if you stay a long time in Spain.
Depending on the offers, you may also have plans with limited data. So if you consume a lot of internet, you need to check carefully beforehand.
Finally, one last important point: not all smartphones are eSIM compatible. Be sure to check your device before choosing this solution.
