JamboSim eSIM Data Plans for Slovenia

JamboSim does not provide a truly unlimited high‑speed data eSIM for Slovenia – the plans listed under “Unlimited” actually offer 3GB/day, after which the speed is reduced to 1000kbps. Travelers who need more data can select from fixed‑data options such as an eSIM Europe 100GB plan valid for 180 days or an eSIM Europe(30+ areas) 50GB plan valid for 30 days, both of which include coverage in Slovenia.

JamboSim provides eSIM plans for Slovenia that include a phone number and the ability to send SMS messages. The plans have a dialing code of +1, meaning the phone number is a US number. Calls can be made but not received, and SMS messages can be sent, although they cannot be received.

The plans range from 1 GB to 20 GB with validity periods spanning 7 days to 365 days. Prices start at $11.99 USD for the 1 GB / 7 day option and go up to $105.99 USD for the 20 GB / 365 day option. Users are encouraged to confirm the specific functionalities directly with JamboSim before purchasing.

JamboSim lists 12 single‑country packages that are usable only in Slovenia, in addition to 112 multi‑country bundles that include Slovenia along with other destinations. The single‑country plans range in price from $0.99 to $196.99 and cover data volumes from 200 MB to 100 GB, and the multi‑country options follow the same price and data ranges while granting access to multiple countries. Within JamboSim’s catalogue, the “daily data cap” plans limit the amount of data that can be downloaded each day, whereas “fixed data cap” plans provide a set total data amount that can be used over the validity period, offering flexibility to match different travel needs.
