Airalo eSIM Data Plans for Spain

Airalo does not provide a truly unlimited high‑speed data eSIM plan for Spain. The plans that carry “Unlimited” in their name deliver 3GB of high‑speed data per day and reduce the speed to 1000kbps once that daily quota is reached, so they do not allow unlimited data at full speed.

If you need a larger data allowance, Airalo offers fixed‑amount plans such as the 100GB plan valid for 180 days and several 50GB plans valid for 30 or 90 days. These plans give you high‑speed coverage in Spain without the daily cap and throttling that applies to the “Unlimited” options.

Airalo does not provide an eSIM for Spain that includes a phone number or SMS capability. Travelers who purchase an Airalo eSIM for Spain receive only a data‑only plan. For voice and messaging, users can rely on popular VoIP applications such as WhatsApp, Telegram, and iMessage, which operate over the data connection.

Airalo offers a total of 18 single‑country plans that are valid only for Spain, and an additional 50 multi‑country plans that include Spain as part of a broader coverage area. The plans cover a broad price spectrum from about $4.00 to $185.00 and data caps ranging from 1 GB to 100 GB. Within these packages, some plans provide a daily data cap—giving a fixed amount of data per day—while others use a fixed data cap that applies for the full validity period, allowing you to choose the structure that best fits your travel style.
