ZenSim eSIM Data Plans for Spain

ZenSim does not provide a truly unlimited data eSIM for Spain. The plans that carry the word “Unlimited” actually grant 3 GB per day and, once that daily amount is reached, the speed is reduced to 1000 kbps.

Travelers who need a larger, unthrottled data allowance can choose ZenSim’s fixed data plans. For example, a 40 GB plan for 30 days costs $45, a 20 GB plan for 15 days costs $21, and a 20 GB plan for 30 days costs $22. These fixed data plans offer a higher data volume without speed reduction and can be more cost‑effective for most users.

ZenSim does not offer any eSIM plans for Spain that include a phone number or SMS capability; only data‑only plans are available. Travelers who need calling or messaging can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these apps are accessible in Spain before purchasing a plan.

ZenSim offers 13 single‑country data plans that can be used in Spain and 18 multi‑country plans that include Spain. The plans vary in price from about $5 to $119 and offer data between 1 GB and 40 GB, with validity periods ranging from 5 to 90 days. Some options are fixed‑data, giving a set amount of data for the entire period, while others use daily data caps that reset each day. Most plans allow tethering, and a reduced speed of 1000 kbit/s applies to a few of them.
