Airalo eSIM Data Plans for Spain

Airalo does not offer truly unlimited data eSIM plans for Spain. The plans that carry the term “Unlimited” only provide up to 3 GB of high‑speed data per day; after that limit is reached, the speed is reduced to 1000 kbps.

Travelers can choose from fixed‑data plans instead. For example, the Eurolink ‑ 100 GB plan gives 100 GB of data for 180 days, while the Guay Mobile ‑ 50 GB plan provides 50 GB for 30 days. These options give larger data allowances without gradual throttling, though they are not unlimited.

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.
