BNESIM does not provide a true unlimited data eSIM for Vietnam. The plan titled “Vietnam Unlimited 10 days” gives 3GB of high‑speed data each day and then throttles to 1Mbps once that daily limit is reached; it is a fixed data plan rather than an unlimited one.
Travelers who need a larger data allowance can choose from BNESIM’s fixed data plans such as the 100GB options that are available for 30 days or without an expiry. These plans offer a substantial amount of high‑speed data before any speed reduction applies and can be more cost‑effective for most users who are not extremely heavy data consumers.
