No, nextSIM does not provide a truly unlimited data eSIM for Belarus. The plans that carry the word “Unlimited” in their name actually have a hard data cap—1 GB or 2 GB per day—and after the limit is reached the speed is throttled to 512 kbps or 2000 kbps.
Instead, nextSIM offers fixed data plans that give a large, unthrottled allowance for a set period. For example, the eSIM EUROPE_LITE 100GB 30Days Premium plan provides 100 GB of high‑speed 5G data for 30 days, and the eSIM EUROPE_LITE 50GB 30Days Premium plan offers 50 GB for the same duration. These fixed data plans can be more cost‑effective for most travelers unless they need an extremely high data volume.
