BNESIM does not offer a truly unlimited high‑speed data eSIM for Bangladesh. The only plan that carries “Unlimited” in its name is Bangladesh Unlimited 10 days, which provides 3 GB at full speed each day; after that limit is reached the speed reduces to 1000 kbps and the data cap resets every 24 hours, so the plan is a fixed‑data plan rather than unlimited.
Travelers can instead choose from fixed‑data plans that give large allowances. For example, Surf 100 GB in Bangladesh for 30 days and Surf 100 GB in Bangladesh with no expiry both deliver 100 GB of high‑speed data for 30 days or until the balance is exhausted. These options tend to be more cost‑effective unless a user needs continuous high‑speed data beyond the allotted data.
