Best eSIM for Spain (2026) — Honest Comparison
Looking for the best eSIM for your trip to Spain? We compare the top eSIM providers — honestly, including our own service and our competitors — across the 4 things that actually matter on the ground: full speed throughout your trip, truly unlimited data (no fair-use policy), full hotspot/tethering, and a native Spanish network connection (not roaming).
TL;DR — Our verdict
For travelers who want to stay connected at full speed all trip long, share data with their laptop or other devices, and use a true Spanish network (not a roaming SIM), Spain Internet is our top pick — full speed always, truly unlimited, no hotspot restrictions, native Vodafone Spain profile, and 9-language support. Holafly has strong brand recognition in Spain but throttles past a daily FUP and restricts tethering. Airalo, Nomad, and Saily are good marketplace options for light data users on a tight budget — be aware they ride on roaming networks and most "unlimited" plans have FUP throttling.
We publish this list to help travelers make an informed choice. We include direct competitors because we believe the best eSIM for you depends on how much data you need, whether you tether, and whether you care about a real Spanish IP.
How we evaluated
eSIMs for Spain travel look similar on the homepage but vary enormously once you start using them. We ranked providers using these six criteria:
Full speed always
No fair-use throttling — full speed throughout your trip, not just for the first GB of the day.
Truly unlimited data
"Unlimited with FUP" is not really unlimited — speeds get throttled to 128 kbps or less after a daily threshold.
Hotspot / tethering
Share your connection with a laptop, tablet, or travel partner — at full speed. Many eSIMs throttle or block tethering even on unlimited plans.
Native Spain network
A real Vodafone Spain profile (not a roaming SIM) means lower latency, fewer roaming hops, and a true Spanish IP — useful for streaming local services.
Multilingual support
Customer service in your language during Spain business hours.
Spain expertise
A provider that specialises in Spain — knows the carriers, the airports, the local device quirks.
