Best eSIM for Spain (2026)
Checked 2026-06.
Checked 2026-06: for most short trips to Spain, a data-only travel eSIM from Airalo or Saily is the cheapest, simplest option — small plans start around US$4 and ride Spain's main networks (Movistar, Orange, Vodafone). Of the two, Saily edges ahead on value for mid-size plans and validity, so it's our default pick.
For the data tiers most travelers actually buy (3–20 GB), Saily's Spain plans tend to come in a touch cheaper and with longer 30-day validity on fixed-data tiers — e.g. roughly US$7 for 3 GB / 30 days and ~US$16 for 10 GB / 30 days (ranges, checked 2026-06) — versus Airalo's comparable plans that often carry shorter 7–15 day windows. Both ride Spain's major networks and activate the same way, so the value math favors Saily for typical 1–2 week stays. Pricing changes often: confirm the current figure on the provider page before you buy.

| Option | Data | Validity | Price | Notes |
|---|---|---|---|---|
| Saily (Spain eSIM) | 1–20 GB fixed; daily 'unlimited' tiers | 7–30 days (most fixed tiers 30d) | ~US$4–$23 (ranges, checked 2026-06) | Data-only; rides Spain's major networks; 10% promo codes common. Best value for 3–20 GB. |
| Airalo (Spain eSIM) | 1–10 GB fixed; daily 'unlimited' tiers | 3–15 days on cheaper tiers | ~US$4–$13 (ranges, checked 2026-06) | Data-only; large provider catalog; shorter validity on low tiers. Big fixed plans (50–100 GB) also available. |
| US carrier roaming pass | ~2 GB/day high-speed then throttled | Per 24h from first use | ~US$12–$15/day (checked 2026-06) | Keeps your number/SMS but costs add up fast — a 2-week trip can hit ~US$170+. Auto-triggers on first connection. |
| Local Spanish prepaid SIM | ~40–380 GB bundles | ~28 days | ~€15–€30 (airport kiosks 30–50% more) | Cheapest per-GB and includes a Spanish number, but needs passport ID, a shop visit, and a SIM-tray phone. |
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. Travel eSIMs from Airalo and Saily connect to one or more of these local networks behind the scenes, so 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 — note those 'unlimited' tiers actually give a few GB per day (commonly 3–5 GB) and then throttle speed.
Validity and price ranges (checked 2026-06): Saily's Spain plans run from about US$4 for 1 GB up to ~US$23 for 20 GB, with most fixed tiers valid 30 days. Airalo's single-country Spain plans start around US$4 for 1 GB (3 days) and rise through the low-to-mid teens for 5–10 GB, but validity is often 7–15 days on the cheaper tiers. Treat every figure here as an approximate range that moves with promos and FX — always 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 that use Spain's major networks. As of 2026-06, Saily tends to offer slightly better value on the popular 3–20 GB tiers and longer 30-day validity, which is why it's our default pick. Airalo has a huge catalog and strong reputation, and is a fine choice too — compare the exact data size you need on each provider's page, since prices shift with promos.
Which Spanish network will my eSIM use?
It depends on the specific plan, but travel eSIMs connect to one or more of Spain's main carriers — Movistar, Orange and Vodafone (sometimes Yoigo). 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 US$10–$25 total. 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.
