Spain eSIM
data from $2.59.

If you are looking for the best eSIM for Spain, buy a data only plan from Slashtel before you fly, from $2.59. It connects automatically to Orange, Movistar, Vodafone or Yoigo, works on 5G where available, and covers city breaks in Barcelona and Madrid, the islands and coastal holidays. Your home SIM stays in the phone for calls and bank codes.

Choosing an eSIM for Spain

What matters is simple: a plan that covers the networks you will actually use, carries enough data for your trip, stays valid for your whole stay, supports hotspot and is installed before you leave.

Coverage comes through the main Spanish networks, Orange, Movistar, Vodafone and Yoigo. The eSIM picks a network automatically, so you do not have to choose or configure one in a menu. This matters in Spain because city travel, island stays and coastal holidays can put you on different networks as you move around.

Data is the second point. A short city break and a two week island holiday need very different allowances, and the plans here run from 1GB up to 50GB. Match the size to the trip rather than buying the largest plan by default.

Validity is the third. Plans last 7, 15, 30 or 180 days, so check that the duration covers your full stay, including the day you fly home. A plan that expires mid trip leaves you without data until you top up.

Hotspot support lets you share the connection with a laptop or a travel companion, which is useful on trains, in apartments and on ferries. Check this before you rely on it for work.

Finally, install the eSIM before you fly. You need a stable connection to add the profile, and doing it at home removes a stressful step at the airport. Our guide to installing an eSIM on iPhone and Android walks through it, and you can confirm your handset first with is my phone eSIM compatible.

Plans and prices for Spain

Slashtel sells Spain plans in seven data sizes and four durations, starting from $2.59, with the price shown live for each size.

The table below lists the data sizes with the available durations and the live from price. Prices update automatically, so the figure you see is the figure you pay.

Smaller sizes suit light use on a short break, while larger sizes suit longer stays, remote work or families sharing a hotspot. All plans are data only, with no local number and no calls or SMS.

Networks and coverage in Spain

The eSIM connects to Orange, Movistar, Vodafone and Yoigo, the main Spanish networks, and selects one automatically, with 5G where it is available.

Spain is well served across its cities and holiday regions, and these four networks operate nationwide. In practice, your phone will attach to a network when you land and stay on it unless coverage drops, at which point it moves to another.

For a Barcelona or Madrid city break, coverage is rarely a concern. For the islands, including the Balearics and the Canaries, and for coastal holidays, coverage depends on where you are, so treat remote coves and mountain roads as places where you may lose signal. Download offline maps before you set off.

Roaming across Spain is part of the plan; you do not need to change settings as you move between regions. If you travel onward to another country, check whether you need a separate plan for that destination.

How much data you need

Pick a size that matches your trip length and how much you will use maps, messaging and video, then add a little headroom.

A simple starting point based on the trip types we list:

• One week: 1GB over 7 days, enough for maps, messaging and light browsing if you stay on WiFi for video.
• Two weeks: 2GB over 15 days, a sensible base for a holiday with regular map and message use.
• One month: 3GB over 30 days, suited to longer stays where WiFi carries most of the load.

If you stream video, take video calls, work remotely or share a hotspot with others, move up to 5GB, 10GB, 20GB or 50GB. Hotspot use in particular burns through data faster than phone use alone, so size up if you plan to tether a laptop.

Install it before you fly

Add the eSIM to your phone at home, on a stable connection, and label it so you can find it later.

Installation takes a few minutes. Follow the steps for your handset in our installation guide, then rename the profile to something obvious such as Spain so it is easy to identify alongside your home SIM.

Keep the eSIM switched off until you land, or enable it on the plane if you prefer. On arrival, turn it on and allow data roaming for that line, which is normal for travel eSIMs. Your home SIM can stay active for calls and texts.

If the eSIM does not connect straight away, toggle airplane mode, check that the Spain line is selected for mobile data, and confirm data roaming is on for that line. Most issues are a setting rather than a coverage problem.

Calls, texts and your home number

The Spain eSIM is data only: there is no local number, no calls and no SMS. WhatsApp and FaceTime calls work over the data connection.

Keep your home SIM in the phone for calls, texts and bank codes. Set the Spain eSIM as the line for mobile data and leave your home line for voice and messaging, so verification codes still arrive and you can call home at your usual rates.

Messaging apps work normally over data, so WhatsApp, FaceTime and similar services cover most day to day contact. For restaurant bookings, taxis and local calls, use an app where possible or your home line.

Questions travellers ask about Spain

The answers below cover the points travellers raise most often before buying a Spain eSIM.

Data only means no local number, so plan calls through apps or your home SIM. Hotspot is supported, the plan starts when it first connects in Spain, and topping up is done through your Slashtel account. Check compatibility before buying.

If you are weighing up the best eSIM for Spain, compare data size, duration, network coverage and hotspot support against your trip rather than looking for a single answer that fits everyone.
