BetterRoaming does not provide an unlimited data eSIM for Spain. The available plans for Spain are fixed data bundles that must be used within a 30‑day validity period. The largest bundle offers 20 GB for $26.99 USD, while smaller options provide 10 GB for $17.99 USD and 5 GB for $11.99 USD.
Choosing a fixed data plan can be more cost‑effective for most travelers, especially if data usage is moderate. Only users who anticipate very heavy data consumption might consider other providers that offer unlimited data options.
