Spain is one of the easiest countries in Europe to get around. The trains connect nearly every major city, the roads are excellent, and mobile coverage across most of the country is genuinely good, which matters more than people expect when they are traveling.
Almost everything you do on a trip now runs on mobile data. Pulling up Google Maps, showing a train ticket at the gate, taking a work call from a cafe in Madrid, sending photos home, all of it needs a fast, reliable connection.
If you are visiting from the UK or elsewhere in the EU, your roaming plan should work in Spain exactly as it does at home, so you may not need to do anything at all. But if you are coming from outside Europe, or your carrier charges heavy roaming fees, an eSIM is the simplest way to stay online from the moment you land.
Why an eSIM makes sense in Spain
An eSIM is a digital SIM built into most newer phones, so there is no physical card to hunt for or swap. You buy a plan online, install it in a few minutes, and it activates the moment you arrive. No airport SIM kiosks, no passport photocopies, no fiddling with a tiny tray and a paperclip.
You also keep your own phone number active in the background, so you stay reachable and can still use WhatsApp, iMessage and the rest over data, exactly as you do at home. Most Spain eSIMs are data-only, which means they do not come with a local Spanish number for regular calls or SMS, but in practice almost everyone uses WhatsApp for that anyway.
Once you buy a plan, the provider emails you an activation guide. You scan a QR code or enter the details manually, and after that you can manage everything from the provider’s app or website, checking your data usage or topping up whenever you need to. You skip roaming charges entirely and get 4G and 5G speeds in the cities and along most of the coast and major highways.

Which network you actually connect to
Spain has four main mobile networks: Movistar, Orange, Vodafone and Yoigo. Coverage across the mainland and the islands is strong on all of them. Most travel eSIMs connect you to one or more of these behind the scenes, so you get the same reliable service the locals do whether you are road-tripping through Andalusia, on a train to Barcelona, or working remotely from Valencia.
Our pick: the Ubigi eSIM
If you want one recommendation that balances price, coverage and easy setup, we would point you to Ubigi. It compares well against the other big eSIM brands and tends to come out ahead on value.
Ubigi is run by Transatel, a Paris-based company that is part of the NTT Group, one of the largest telecom companies in the world. It has been in the eSIM business since 2017, so it is one of the more established names rather than one of the many newcomers that appeared in the last couple of years. In Spain, Ubigi connects primarily to the Orange network, with Yoigo as an automatic fallback, so if one network is congested or weak in a particular spot, your phone can switch to the other. That dual-network access gives it a small but real reliability edge.

A few things worth knowing about Ubigi:
- Coverage in 190+ destinations worldwide
- Data plans ranging from small 500 MB top-ups to large 60 GB packages, plus an unlimited 30-day Spain plan
- Spain plans that run from just a couple of dollars for a small allowance up to about $44 for the unlimited 30-day option
- Single-country Spain plans if you are only visiting Spain, or regional and global plans if you are traveling more widely
- 4G and 5G speeds, with 5G available in 90+ destinations
- Your own number stays active for WhatsApp and iMessage; the Spain plans are data-only, so no local calls or SMS
- Unlimited hotspot and tethering, which is handy if you travel with a laptop or tablet
Ubigi’s reliability comes from sitting inside a large global telecom group with its own infrastructure across several continents, and from striking direct deals with local operators to get good pricing and wide coverage.
One genuinely useful feature is that a single Ubigi eSIM works across borders. If you cross from Spain into France or Portugal, or you simply run low, you top up or switch plans in the app without scanning a new QR code each time. Install it once and you can reuse the same eSIM on future trips too.
How to set up your Ubigi eSIM
The process is quick. First, check that your phone supports eSIM (most models from the last few years do). Then:
- Visit the Ubigi website or app and search for your destination, in this case Spain
- Choose the data plan that fits your trip length and how much data you expect to use
- Create your account, complete the purchase, and you will receive a QR code by email
- Scan the QR code to install the eSIM, ideally before you leave home
Installing before your trip is the smart move, because then you just switch the plan on in your phone settings when you land. Your plan does not start when you buy it; it starts when you connect to the network on arrival, so there is no risk of wasting days. After that, the eSIM is yours to reuse on future trips without reinstalling.
If you run out of data or credit, you can still top up from inside the app even without WiFi, since Ubigi covers the connection for the minute it takes to complete the top-up.
Monthly and annual plans
Ubigi’s monthly plan gives you a set data allowance that renews each month, with the flexibility to cancel any time after the first three months. The annual plan suits heavier, regular users: you pay once for twelve months, your data renews monthly, and there are no extra monthly charges on top. For a single trip, a straightforward one-off data package is usually all you need.
How much data should you get?
The one decision worth thinking about is how many gigabytes you will actually use and for how many days. Ubigi publishes a simple usage guide on its site that estimates typical consumption, so you can match a plan to your habits rather than guessing. It lays all the options out in one view, which not every provider makes easy.

Do you need the app?
You do not have to download the app to use a Ubigi eSIM, which sets it apart from some competitors. You can buy a plan on the website and add it to your phone manually. The app is still handy for checking your remaining data and managing plans, but it is optional, not a requirement.
Customer support
Ubigi has a detailed help and FAQ section covering the common setup and troubleshooting questions. If you cannot find what you need, you can message the team or use the live chat on the site. The website and app are available in 14 languages, with more being added.
Our honest take
Spain is already an easy country to travel, and a good eSIM just smooths out the small friction of staying connected. For anyone coming from outside Europe, it beats searching for a SIM card on arrival or leaning on patchy public WiFi. You activate a plan in minutes and you are online from the moment you step off the plane.
What stands out about Ubigi is the wide coverage, the Orange-and-Yoigo dual network in Spain, the 5G availability and the honest pricing, including an unlimited Spain plan for anyone who burns through a lot of data. It is the one we would set up ourselves for a trip here.
