eSIMCard does not provide a true unlimited high‑speed data plan for Bangladesh. Every plan labeled “Unlimited” in the package name actually offers a capped amount of high‑speed data—typically 1GB/day or 2GB/day—and once the threshold is reached the speed is reduced to 512kbps or 2000kbps. Because the plans are throttled after the cap, they are not unlimited in the sense of offering unlimited high‑speed data.
If a traveler needs a larger data allowance without throttling, eSIMCard offers fixed data plans such as the 100GB for 180 days Global (unthrottled) plan and the 53.69GB for 60 days plan in Bangladesh. These plans provide a large, fixed data allotment that can be more cost‑effective for heavy users compared to the throttled “Unlimited” options.
