Best eSIM for Spain (2026)
Checked 2026-06.
Checked on the Airalo and Saily sites on 26 Sep 2026 (prices in euros as shown there): for most short trips to Spain a data-only travel eSIM is the cheapest, simplest option. Airalo is our pick for the 5-20 GB most travelers buy - €8.50, €13.00 and €18.00 for 5, 10 and 20 GB over 30 days on Orange's 5G network, against €8.99, €13.99 and €20.49 at Saily - while Saily is cheaper for 1-3 GB (€3.49 for 1 GB over 7 days, €5.99 for 3 GB over 30 days).
For the data sizes most travelers buy, Airalo's Spain eSIM is a little cheaper than Saily with the same 30-day validity: €8.50 for 5 GB, €13.00 for 10 GB and €18.00 for 20 GB (Saily: €8.99, €13.99, €20.49), and it adds a 50 GB plan (€35.00) and shorter 3-, 7- and 15-day options. It runs on Orange with 5G. If you only need 1-3 GB, Saily is cheaper: €3.49 for 1 GB over 7 days and €5.99 for 3 GB over 30 days. Both unlimited ranges give 5 GB a day at full speed, then 1 Mbps.

Networks and coverage: Spain has three major mobile networks — Movistar, Orange and Vodafone (plus Yoigo/MasMovil) — and all give strong nationwide 4G with widening 5G in cities, beach towns and along main routes. Airalo's Spain eSIM runs on Orange with 5G; Saily doesn't name its Spanish networks. Real-world coverage in tourist areas is excellent. If you spend a lot of time in rural villages or the mountains, Movistar tends to have the deepest reach; for normal city-and-coast trips the difference between providers is small.
Activation: both Airalo and Saily are bought in-app or online before you fly. You receive a QR code (or one-tap install on supported phones), add the eSIM under your phone's cellular settings, and toggle on data roaming for that line when you land. Your home SIM keeps your number for calls and texts; the travel eSIM just carries data. Tip: install the eSIM on home Wi-Fi before departure, but only switch it on once you arrive — the validity clock starts at activation, not at purchase.
Data sizing: as a rough guide, light use (maps, messaging, occasional browsing) runs about 1 GB per 2–3 days; moderate use with some streaming is closer to 1 GB/day; heavy video or hotspot use can be 2 GB+/day. For a typical one-week city trip, 3–5 GB is comfortable; for two weeks of regular use, 10 GB is a safe middle ground. Both providers also sell large fixed-data plans (20 GB+) and 'unlimited' daily plans — both 'unlimited' Spain ranges give 5 GB a day at full speed and then slow to 1 Mbps.
Validity and price (checked 26 Sep 2026 on both sites, in euros): Saily Spain sells 1 GB for 7 days (€3.49) and 3, 5, 10 or 20 GB for 30 days (€5.99, €8.99, €13.99, €20.49). Airalo Spain runs from €4.00 for 1 GB over 3 days to €35.00 for 50 GB over 30 days, with 3-, 7-, 15- and 30-day options; its 30-day plans cost €8.50 (5 GB), €13.00 (10 GB) and €18.00 (20 GB). Unlimited: Airalo €10.00 (3 days) to €56.50 (30 days), Saily €14.99 (5 days) to €56.99 (30 days). Prices move with promotions, so confirm the live price on the provider's page before paying.
Gotcha to watch: these are data-only eSIMs with no Spanish phone number or SMS, so use WhatsApp/iMessage/Telegram over data for calls and messages, and keep your home line for any bank OTP texts. Also check the plan's geographic scope — a single-country 'Spain' eSIM may not work in neighboring Portugal or elsewhere in the EU, so if your trip crosses borders, buy a Europe-wide plan instead.

FAQ
Which is better for Spain, Airalo or Saily?
Both are reliable data-only eSIMs. As of 26 Sep 2026, Airalo is a little cheaper for 5-20 GB with the same 30-day validity (€8.50 / €13.00 / €18.00 against Saily's €8.99 / €13.99 / €20.49) and runs on Orange with 5G, so it's our default pick; Saily is cheaper for 1-3 GB. Compare the exact size you need, since prices shift with promos.
Which Spanish network will my eSIM use?
It depends on the provider: Airalo's Spain eSIM uses Orange (5G); Saily doesn't say which Spanish network it uses. Coverage in cities, tourist towns and along main routes is excellent on all of them. For deep rural or mountain areas, Movistar generally has the widest reach.
Is an eSIM cheaper than using my US carrier's roaming in Spain?
Almost always, yes. US daily roaming passes run about US$12–$15/day (checked 2026-06), so a two-week trip can exceed US$170 on one phone. A travel eSIM for the same trip is often €13-€20 in total (10-20 GB over 30 days, checked 26 Sep 2026). The trade-off: the eSIM is data-only, so you keep your home line for calls/SMS and use apps like WhatsApp over data.
Can I use a Spain eSIM in other countries?
A single-country 'Spain' plan usually works only inside Spain — it may not cover Portugal, France or the rest of the EU. If your itinerary crosses borders, buy a Europe-wide eSIM instead. Always check the plan's listed coverage area before you buy.
