Supera link does not provide an unlimited data eSIM plan for Slovenia.
The available offer for Slovenia is a fixed‑data plan called Global 109 Countries - 5GB/day, which delivers 5 GB of high‑speed data per day for validity periods of 7 days, 10 days, 15 days, 20 days or 30 days. Prices range from $42.01 USD for 7 days to $175.68 USD for 30 days. Fixed daily data allows many travelers to manage costs more predictably unless they anticipate extremely heavy data consumption, in which case other providers would need to be explored.
