eSIMsData does not provide a true unlimited data eSIM for Spain. All of the plans that carry “Unlimited” in their names still list a hard data cap in the Data cap column. For example, the Spain Unlimited Essential 30 Days plan supplies 1GB/day (30GB total) of high‑speed data, and the Spain Unlimited Plus 30 Days plan supplies 2GB/day (60GB total). After the listed cap the speed is throttled to 1250 kbps or 2000 kbps, respectively, so the data is not unlimited.
Users who want larger amounts of data can choose eSIMsData’s fixed data plans instead. A 30‑day plan with 1GB/day high‑speed data offers 30GB in total, while a 30‑day Spain 100GB plan delivers a 100GB data allowance at high‑speed. These plans give a fixed amount of data for the specified validity period and are more cost‑effective for most travelers than the capped “Unlimited” offerings.
