Esimatic does not provide an unlimited data eSIM option for travelers heading to Spain. The provider’s available plans for Spain give a fixed allowance of 100GB for a 30‑day period.
If you need more data than a typical traveler will use, a fixed data plan can be a more economical choice. For example, the Spain plan offers 100GB for 30 days at a price of about $94.18 USD, and the Europe Lite plan offers the same 100GB amount for 30 days at roughly $99.99 USD. These plans cover Spain along with additional countries, and they represent only a subset of the plans that Esimatic offers. Choosing a fixed data plan rather than searching for a truly unlimited option may save money unless extremely heavy data usage is required.
