GlobaleSIM does not provide an unlimited data eSIM for Spain. The available options for Spain are fixed data plans, such as a 20GB bundle valid for 30 days priced at $15.00 USD and a 15GB bundle also valid for 30 days priced at $12.00 USD.
Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user expects to consume data well beyond the bundle limits.
