Bordersim does not provide an unlimited‑data eSIM for Spain. All its Spain‑specific plans have a fixed data allowance listed in the Data cap column, such as 50GB for 30 days or 100GB for 180 days. The validity periods are tied to the connection time of the eSIM, as indicated in the provider notes.
Travelers who need a high data quota can choose from Bordersim’s fixed data plans that cover Spain. For example, the Spain 50GB plan is valid for 30 days at $22.99 USD, and the Europe (35 areas) 100GB plan covers 180 days for $85.99 USD. These fixed data bundles may be more cost‑effective for users who do not require truly unlimited data.
