Yes, abesteSIM provides unlimited‑data eSIM options for Slovenia. The provider offers several paid plans that have no data cap for durations ranging from 1 day to 30 days, with prices that start around $1.92 for a one‑day plan and can rise to about $113.80 for a 20‑day limit. These unlimited plans are listed as offering 5G coverage in Slovenia and include a maximum speed when used at normal pace, but the provider may throttle speeds after heavy usage, a standard fair‑usage practice. If you need more details about the speed restrictions or the exact amount of data you can expect at full speed, it is advisable to contact abesteSIM directly.
