ByteSIM does not provide a truly unlimited data eSIM for Bangladesh. The plans that carry “Unlimited” in their names actually offer a fixed 1 GB data allowance per day, after which the speed is reduced to about 10 240 kbps. Instead, ByteSIM offers fixed high‑data plans, for example a 30 GB plan valid for 3, 5, 7, 10 or 15 days. These plans allow full‑speed 4G or 5G data until the 30 GB cap is reached, after which no further data is provided. Choosing one of these fixed‑data options can be more cost‑effective than a plan labeled “Unlimited” that has a low daily data cap.
