The best eSIM for Spain

Spain runs on four national operators: Movistar, Orange, Vodafone and Yoigo. Most travel eSIMs roam onto Movistar or Orange, which have the widest rural reach.

In Madrid, Barcelona and the larger Andalusian cities all four deliver fast 5G, so the host network barely matters.

It starts to matter inland — Extremadura, rural Castilla and the Pyrenees — where Movistar's legacy footprint is noticeably deeper.

The Balearics and Canaries are well covered around the resorts, thinner on the volcanic and mountain roads.

Every major Spanish tourist city has dense 5G, including the old quarters where signal often struggles elsewhere in Europe.

The Mediterranean coast from Barcelona down to Málaga is consistently strong, though beach areas slow down in August peak season.

Island trips are fine in Palma, Ibiza Town, Santa Cruz and Las Palmas; expect 4G on the smaller island roads.

Hiking areas such as the Picos de Europa or Teide National Park have real dead zones — download maps before you set out.

If Spain is your only stop, a single-country plan is almost always the cheaper option per gigabyte.

Adding Portugal, France or Italy to the itinerary usually flips the maths toward a Europe regional plan.

Regional plans also help on Spain–Morocco or Spain–Andorra hops, where a local plan simply stops working.

Both use the same Spanish host networks, so you are choosing on price and flexibility, not on speed.
