Airdatalink offers 216 multi‑country eSIM data plans that include Spain. All of these plans are multi‑country offerings; there are no single‑country plans available for Spain. The multi‑country options vary by data amount and validity, and they come in two main styles: fixed data caps, where a set amount of data (from 500 MB up to 50 GB) is allocated for the full validity period, and daily data cap plans, where a fixed daily data allowance is applied over the plan’s duration.
The available plans cover a price range from about $1.82 to $151.80, and the data caps span from 500 MB up to 50 GB. Validity periods differ from a single day to up to 90 days, giving travelers flexibility to choose the duration that best fits their trip.
