ZenSim eSIM Data Plans for Spain

ZenSim does not provide a truly unlimited data eSIM for Spain. All plans that carry “Unlimited” in the name actually limit the high‑speed data allowance to 3 GB per day; after the daily limit is reached the speed is reduced (the specific reduced speed is not listed in the available data).

Instead, ZenSim offers fixed‑data plans that can be more cost‑effective for most travelers. Examples include a 40 GB plan for 30 days priced at $45.00 USD and a 20 GB plan for 10 days priced at $21.00 USD. These plans give a fixed amount of high‑speed data and do not contain a daily reduction clause.

ZenSim does not provide any eSIM plan for Spain that includes a phone number or SMS capability. All of ZenSim’s Spain offers are data‑only, so travelers can use services such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging instead of a traditional phone number.

ZenSim offers nine single‑country data plans for Spain and nine multi‑country plans that include Spain. The plans are split into fixed data‑cap and daily‑cap options. Fixed‑cap plans grant a set amount of data—ranging from 3 GB up to 40 GB—for the full validity period of 10 to 30 days, while daily‑cap plans limit the amount of data that can be used each day but otherwise follow the same duration and price ranges. Across all plans the price ranges from about $10 to $65 USD, giving customers a wide selection of data volumes and costs.
