MobineX does not provide a truly unlimited data eSIM for Vietnam. All of its “Unlimited” plans have a fixed data cap, such as 1GB for one day or 5GB for one day, and after the cap is reached the speed is reduced to 128kbps or 1024kbps.
Instead of an unlimited option, mobineX offers several high‑data fixed plans that may be more suitable for heavy users. For example, a 28GB plan valid for three days or a 42GB plan for five days can provide ample high‑speed data for a longer period before the cap is reached. Choosing one of these fixed‑data plans can be more cost‑effective for travelers who need substantial data usage while in Vietnam.
