JamboSim eSIM Data Plans for Spain

JamboSim does not provide a truly unlimited data eSIM for Spain. Every plan listed under the “Unlimited” name offers a maximum of 3GB per day, and once that daily quota is reached the speed is reduced to 1000kbps. Thus the name “Unlimited” refers to continuous access with a fixed daily limit rather than an unrestricted high‑speed data allowance.

For travelers who need a larger, non‑throttled data allotment, JamboSim offers fixed‑data plans. Examples include a 100GB plan valid for 180 days and a 50GB plan valid for 30 days. These plans provide a large amount of high‑speed data without the daily quota, making them a more cost‑effective choice for users who are heavy data consumers in Spain.

JamboSim offers Spain eSIM plans that include a phone number and the ability to send SMS. The plans range in data cap from 1GB to 20GB, validity from 7 days to 365 days, and prices from $11.99 USD to $105.99 USD. Each plan provides a phone number with the dialing code +1, which is a US number rather than a local Spanish number. The telephony features allow outbound voice calls and outbound SMS, but inbound voice and SMS are not supported. Users wishing to use these services should confirm the details directly with JamboSim to ensure they meet their specific requirements.

JamboSim has a total of 12 single‑country plans that cover Spain and 96 multi‑country plans that include Spain as part of a larger regional bundle. The available plans span a price range from $0.99 to $195.99 and a data cap range from 200 MB to 100 GB, with validity periods between 1 and 365 days. Within these offerings, plans may be structured as fixed data amounts, lasting for the full validity period, or as daily data caps that reset each day. Many of the plans allow tethering, and a reduced speed option of 1000 Kbps is available for some packages.
