Airalo eSIM Data Plans for Spain

Airalo does not provide a truly unlimited data eSIM for Spain. The plans that carry the name “Unlimited” actually give 3GB of high‑speed data per day; after that allocation the speed drops to 1000kbps. If a traveler wants no data cap, the alternative is a fixed‑data plan. For example, a 100GB plan is valid for 180 days, and a 50GB plan is valid for 30 days; both deliver high‑speed LTE coverage throughout Spain. Choosing a fixed data plan can often be more cost‑effective than paying for an “Unlimited”‑named plan that still has limits.

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 data plans that are specifically for Spain and 32 multi‑country plans that cover Spain along with at least one other destination. The available plans span a price range from about $4 up to $185, with data caps that can be as low as 1 GB or as high as 100 GB. Validity periods vary from a minimum of 3 days to a maximum of 365 days. Among the plans, 7 are structured around a daily data cap model, which limits the amount of data you can consume each day, while 43 plans provide a fixed data amount that can be used over the entire validity period.
