The Best eSIM for Spain
Six providers across fourteen spec points and published traveller reviews. Two we would not buy.
Some links on this page earn us a commission. Your price is the same either way. How this works
If you are travelling on a non-EU plan, one day of roaming in Spain costs more than a month of eSIM data. Buy before you fly; it activates when you land.
The verdict
| Provider | Plan | Verdict | |
|---|---|---|---|
| AiraloEurope regional | 10GB / 30 days · $23 | Best overall | Get Airalo |
| NomadSpain local | 10GB / 30 days · $19 | Cheapest we would use | Get Nomad |
| HolaflySpain unlimited | Unlimited / 30 days · $34 | Only if you never tether | Get Holafly |
| Airport SIM kioskT1 and T2 arrivals | Physical SIM, paid at the desk | Not recommended: you queue after a flight, hand over a passport, and pay a walk-up price | No link |
| Your carrier’s roaming add-onHome network | Priced per day or per MB | Fine inside the EU on an EU contract. Outside it, the daily fee usually beats the whole eSIM in under a week | No link |
Why two rows have no link: a comparison where every option ends in a buy button is a sales page, and readers discount all of it. Anything scoring below our threshold gets listed without an affiliate link, which costs us nothing we were going to earn anyway.
What actually matters when choosing
Regional beats local if you are moving. A Spain-only plan is a few dollars cheaper, but a Europe regional plan covers 39 countries on the same eSIM, which matters the moment your trip includes Lisbon or Marseille.
Unlimited plans usually block tethering. If you work from a laptop, unlimited-without-hotspot is worse than a 10GB plan that lets you share. Read that line before the price.
Check your phone is carrier-unlocked. Every eSIM on this page needs an unlocked handset. Any iPhone from XR onward and most Android flagships since 2020 support eSIM.
Questions
Any iPhone from XR onward and most Android flagships released since 2020. Your phone must be carrier-unlocked. If you bought it outright rather than on a contract, it almost certainly is.
Yes. The eSIM is a second line used for data only, so calls and texts stay on your physical SIM. Turn data roaming off on the physical line to avoid charges.
Install before you fly, on wifi, but do not activate until you land. Most plans start counting their validity window from first connection rather than from purchase.
You top up in the provider app, which needs a connection. Keep a small credit-card-free top-up option available, or buy slightly more data than you think you need.
