ZenSim eSIM Data Plans for Slovenia

ZenSim does not provide a truly unlimited data eSIM for Slovenia. The plans that carry the “Unlimited” label, such as the Europe+ Unlimited STANDARD options, actually grant a fixed high‑speed allowance of 3 GB per day for the validity period, after which the speed is reduced. For travelers who need a higher data volume, ZenSim offers several fixed‑data alternatives. For example, the Slovenia 20GB plans are available for both 10‑day and 30‑day periods, as well as a Slovenia 10GB plan for 10 days and Europe+ 20GB plans that include coverage of Slovenia and 35 other countries. Choosing a fixed‑data plan can be more cost‑effective unless a user requires very high bandwidth without any data caps.

ZenSim does not provide an eSIM for Slovenia that includes a phone number or SMS capability. The only plans available for Slovenia are data‑only, giving access to mobile data via 5G/4G/3G networks. Travelers can still make and receive calls and send messages through VoIP applications such as WhatsApp, Telegram, and iMessage, which operate over the data connection.

ZenSim provides six single‑country plans and eight multi‑country plans for Slovenia. The available packages range in price from $11 to $57, with data caps spanning 3 GB to 20 GB and validity periods of 10 to 30 days. Some plans use a daily data cap while others offer a fixed data amount; tethering is allowed on applicable plans.
