ZenSim eSIM Data Plans for Slovenia

ZenSim does not provide a truly unlimited high‑speed data eSIM for Slovenia. All of its Slovenia‑specific offerings are fixed data plans, such as a 40 GB plan for 30 days at $45.00 USD and a 20 GB plan for 30 days at $24.00 USD.

Plans that carry “Unlimited” in the name, like the Europe+ Unlimited STANDARD lines, actually allow 3 GB of high‑speed data per day; after that limit the speed is throttled. Choosing a fixed‑data plan can be more cost‑effective, especially for travelers who need a large amount of data.

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 offers 7 single‑country plans that cover Slovenia alongside 9 multi‑country plans that include Slovenia within their coverage. Prices for these options range from about $11.00 to $57.00, while data caps vary between roughly 3 GB and 40 GB, depending on the specific plan. The provider provides both fixed‑data packages and a small selection of daily‑data‑cap plans, allowing users to choose a fixed amount of data for the validity period or a lower daily limit with the same overall cap.
