Heading to Spain? You'll want mobile data from the moment you land, for maps, messages and sharing photos, without queuing at a SIM shop or paying home-network roaming charges. An eSIM installs before departure and activates on arrival, so you get a local connection without touching a physical card. On 27 October 2026 we compared Spain eSIM prices across ONE eSIM, Airalo, Holafly, Saily and Nomad, matched by data amount and validity, to find the cheapest option for your trip. ONE eSIM splits its Spain traffic across two local 5G partners, Orange and Movistar, which is more redundancy than a single-network eSIM gives you.

Holafly sells only unlimited plans for Spain, so it has no price in the GB rows; its 7-day plan is in the week table below.
A week of unlimited data in Spain
| Provider | 7 days | What you get |
|---|---|---|
| ONE eSIM | $10.43 | 1 GB a day at full speed, then 512 Kbps until the next day (7 × $1.49) |
| Airalo | $23.50 | 3 GB a day at full speed, then 1 Mbps (fair use) |
| Holafly | $24.50 | No daily cap; fair use may slow very heavy use |
| Saily | $22.99 | 5 GB a day at full speed, then up to 1 Mbps |
| Nomad | $25.00 | 2 GB a day at full speed, then 1 Mbps |
For a week, ONE eSIM's 1 GB a day plan is the cheapest way to stay online all day at $10.43. The cheapest of the others is Saily at $22.99, which gives more full-speed data a day; compare by how much you use a day, not by the word unlimited.
Networks and coverage in Spain
ONE eSIM's Spain plans connect through Orange [5G], Movistar [5G]. With two 5G partners sharing the load, a dead spot on one network often still has coverage on the other. Because an eSIM rides on the same local infrastructure as a physical SIM, expect the same signal strength you'd get from a phone bought in the country, minus the shop queue.
