RedSim does not offer a true unlimited data eSIM for Slovenia. The plans that use the word “Unlimited” actually provide a fixed daily high‑speed data allowance—either 3GB per day or 5GB per day—after which the speed drops to 1 Mbps for the rest of the day. These plans are described as having reduced speed after the daily cap.
Travelers who need a larger data pool can choose a fixed data plan instead. For example, the Slovenia 20GB 30 days plan costs $18.98 USD, and the Europe (28 countries) 50GB 30 days plan costs $47.60 USD. Both of these plans offer a fixed amount of high‑speed data over a 30‑day validity period and do not impose the daily caps that appear in the “Unlimited” plans. Choosing a fixed data plan can be more cost‑effective unless very heavy data usage is required.
