Best eSIM for Spain (2026): Mobile Data From the Costa del Sol to the Canaries
The best eSIM for Spain gives you mobile data from the moment you land in Malaga, Alicante, Barcelona or Tenerife, without buying a Spanish SIM and without UK roaming fees. For holidays and short trips, Saily is the best value. For long winter stays on the Costa Blanca or months of remote work in Valencia, Holafly’s unlimited data is the better choice. This guide compares both and shows you how to set up the best eSIM for Spain before you fly.
Spain is the most popular destination for British holidaymakers and home to one of the largest British expat communities in the world. Since Brexit, several UK networks charge daily fees for EU roaming, so picking the best eSIM for Spain is one of the easiest ways to cut your travel costs.
Best eSIM for Spain: The Quick Answer
Saily is the best eSIM for Spain for holidays, city breaks and trips of a few weeks. It sells fixed data plans at low prices, includes an ad blocker and web protection, and is built by Nord Security, the company behind NordVPN.
Holafly is the best eSIM for Spain for long stays and heavy data use. Every plan includes unlimited data for the number of days you choose, and support runs 24/7 by live chat and WhatsApp.
If your trip also takes in Portugal, France or other European countries, a regional Europe plan covers Spain and its neighbours on one eSIM. Our guide to the best eSIM for Europe compares the regional options, and our best eSIM for Portugal guide covers the next-door favourite.
Why British Travellers Need the Best eSIM for Spain
Before Brexit, UK phone plans roamed in Spain at no extra cost. Today, several UK networks charge a daily fee to use your allowance in the EU, and those charges add up over a fortnight on the Costa del Sol or a three-month winter stay.
A travel eSIM avoids that. You pay for a data plan sized to your trip, while your UK SIM stays in the phone for calls and bank security texts. Our guide to keeping your UK number abroad explains the full dual-SIM setup.
You also skip the search for a Spanish SIM shop on arrival. The best eSIM for Spain is installed at home, so you walk out of Malaga or Alicante airport already connected.
Best eSIM for Spain for Holidays: Saily
Saily is the best eSIM for Spain if you mainly use maps, messaging, ride-hailing and social media. You pay for a fixed amount of data, so a short holiday stays cheap. Saily also offers a Europe plan covering 35 countries from US$3.99, which suits a trip that combines Spain with Portugal or France.
The built-in ad blocker blocks ads before they load, which stretches your data further. Web protection warns you about dangerous websites, which helps on unfamiliar networks and on the public WiFi you will find in beach bars and hotels.
Prices for Spain change from time to time, so check the current plans in the Saily app before you buy. Our Saily eSIM review covers speed tests and the app in detail.
Best eSIM for Spain for Long Stays: Holafly
Thousands of British retirees spend the winter on the Costa Blanca, the Costa del Sol and the Canary Islands, and Valencia and Barcelona attract many remote workers. A fixed data allowance runs out quickly when you video call family, stream TV and work from your phone every day.
Holafly is the best eSIM for Spain in that situation, because every plan includes unlimited data for 1 to 90 days. It is priced per day rather than per gigabyte, so it costs more for light users but removes any need to count your data. Hotspot sharing is limited to roughly 500 MB to 1 GB per day on standard plans.
Our Holafly review covers fair use and Europe plan prices in detail.

Coverage and Speed: Which Spanish Networks Do eSIMs Use?
Spain’s main mobile networks are Movistar, Vodafone and Orange, with smaller operators such as Digi using their infrastructure. Travel eSIMs connect to these local networks, so your coverage matches a Spanish SIM on the same network. 4G covers almost every town and resort, and 5G is widely available in Madrid, Barcelona, Valencia, Malaga and other large cities.
Coverage is strong along the Costa del Sol, Costa Blanca and Costa Brava, where most British visitors stay. In the mountains of Andalucia and parts of rural inland Spain, speeds can drop, as they do for every Spanish SIM.
Does the Best eSIM for Spain Work in the Canary and Balearic Islands?
The Canary Islands and the Balearic Islands are part of Spain, and Spain plans normally include them. Tenerife, Gran Canaria, Lanzarote, Fuerteventura, Mallorca, Menorca and Ibiza all have good 4G coverage in their main towns and resorts.
Check the coverage list in the app before you buy, especially if you plan to visit the smaller islands. It takes a minute and avoids any surprise on arrival.
How Much Data Do You Need in Spain?
Light use on a one-week holiday: maps, messages, ride-hailing and a few photo uploads usually fit within 3 to 5 GB, so a small Saily plan is enough.
Moderate use on a two-week trip: add video calls home, music streaming and social media, and 10 GB is the safer choice. You can top up in the app if you run low.
Heavy use on a long stay: evening streaming, daily video calls and remote work can use several gigabytes a day. At that level, Holafly’s unlimited data is simpler than buying top-ups.
Best eSIM for Spain or a Spanish SIM Card?
A Spanish prepaid SIM from Movistar, Vodafone or Orange can be cheaper per gigabyte, but buying one takes time. Shops ask for your passport to register the SIM, and the airport kiosks usually charge more than high street stores.
A travel eSIM skips all of that. You buy and install it at home in a few minutes, keep your UK SIM in the phone, and avoid queues on your first day in Spain.
For most holidays and the first weeks of a move, the best eSIM for Spain is the simpler choice. A local contract makes more sense once you have a Spanish address, a bank account and plans to stay for good.
How to Set Up the Best eSIM for Spain Step by Step
Step 1: Check That Your Phone Supports eSIM
Most iPhones from the iPhone XS onward and most Samsung Galaxy phones from the S20 onward support eSIM. Your phone also needs to be unlocked to accept an eSIM from another provider.
Step 2: Install the eSIM at Home
Buy your plan in the Saily or Holafly app and install the eSIM while you still have WiFi. Label it Spain Data so it is easy to find in your settings.
Step 3: Switch On When You Land
After landing, set the eSIM as your mobile data line and turn on data roaming for that line only. Turn off data roaming on your UK SIM to avoid daily roaming fees, but keep it on for calls and bank codes.

Tips for British Expats in Spain
You may need a Spanish number later. Renting long term, opening a Spanish bank account or registering for local services often requires a Spanish phone number. Many expats sign a local contract once they settle and rely on the best eSIM for Spain for their first weeks.
Keep your UK number active. UK banks, HMRC and the DWP still send codes to your UK number, so keep that SIM in the phone and use the eSIM only for data.
Check official guidance. The UK Foreign Office travel advice for Spain covers entry rules, and Spain’s telecom and competition regulator, the CNMC, publishes information on mobile services.
Pair Your Spain eSIM With a VPN
An eSIM gives you a Spanish connection, but BBC iPlayer, ITVX and Channel 4 block viewers outside the UK, and many UK banking apps flag foreign IP addresses. A VPN with UK servers fixes both, on eSIM data and on hotel or apartment WiFi. See our guides to BBC iPlayer in Spain and ITVX in Spain for step-by-step help.
Our guide to the best VPN for expats in Spain explains the setup, and our article on whether a VPN is legal in Spain answers the most common question. NordVPN pairs naturally with Saily because both come from Nord Security, and Proton VPN is a strong privacy-first alternative.
Our Verdict: Best eSIM for Spain in 2026
For holidays and short trips, Saily is the best eSIM for Spain on price and simplicity. For a winter on the Costa Blanca or months in the Canaries, Holafly’s unlimited data is worth the higher daily cost. Whichever you choose, keep your UK SIM for bank codes and add a VPN for UK banking and television.

The Canary Islands are part of Spain, and Spain plans normally include them. Check the coverage list in the app before you buy.
Which networks do eSIMs use in Spain?
