Airalo does not provide a truly unlimited data eSIM for Bangladesh. The plans that carry the word “Unlimited” in their title give 3GB of high‑speed data per day; after that amount the speed drops to 1Mbps. Therefore, the day‑to‑day data allowance is capped, not unlimited.
If a user needs a large amount of data without any daily limits, Airalo offers fixed data plans that can be used for a set period. For example, a 100GB plan is available for 180 days, and a 50GB plan is sold for 30 days. These fixed plans allow the full amount of data to be used at full speed until the validity expires, which can be more cost‑effective for heavy data users.
