simpleSIM does not provide a truly unlimited data eSIM for Spain. All of the plans listed for Spain have a hard data cap, even those that include “Unlimited” in the name. The largest data allowance available is 50GB for 30 days, and other options include 20GB for 30 days or 20GB for 14 days, each with a fixed validity period.
Travelers who need more data can choose from these fixed data plans. For example, the 20GB plan is valid for 30 days, and the 50GB plan is valid for 30 days. These plans offer a set amount of high‑speed data and can be more cost‑effective unless the user is an extremely heavy data consumer.
