nextSIM does not have a genuinely unlimited data eSIM for Belarus. The plans that carry the word “Unlimited” in their names, such as eSIM Unlimited Standard 1 Day Belarus or eSIM Unlimited Plus 3 Days Belarus, actually cap the high‑speed data at 1 GB or 2 GB per day and then reduce the speed to 512 kbps or 2000 kbps once the limit is reached.
For travelers who need more data, nextSIM offers fixed‑data plans that can be more cost effective. For example, the eSIM EUROPE 50GB 30Days Premium plan gives 50 GB of high‑speed data for 30 days at a lower price than the “Unlimited” options, and similar 30 GB or 50 GB plans are available for Belarus coverage. These plans provide a larger data allowance with no speed throttling until the stated cap is reached.
