ByteSIM does not provide a truly unlimited data eSIM for Belarus. The plans that carry the name “Unlimited” actually grant 1 GB of high‑speed data per day and, once that limit is reached, the speed drops to 10 240 kbps. Because the data allowance is capped, the plans are not unlimited in the sense of endless high‑speed traffic.
Travelers who need a larger or truly unlimited data capacity can opt for ByteSIM’s fixed‑data plans instead. For example, the 50 GB plan for 5 days costs about $62.90 USD, and the 50 GB plan for 15 days costs about $69.90 USD. These plans offer a set data allowance without a reduction in speed once the cap is reached, providing more predictability for heavy data users.
