Stellar eSim does not provide a truly unlimited data eSIM for Vietnam. The plans labeled “Unlimited” actually contain a 2GB or 3GB high‑speed data allowance that must be used within the specified validity period. When the allotted data is exhausted, the plan does not continue to offer unlimited high‑speed access.
Instead, travelers can choose from a variety of fixed‑data plans. For instance, the Vietnam eSIM Unlimited – 30 days plan gives 3GB for 30 days, and the 50GB 90‑day plan offers 50GB for 90 days. These fixed plans can be a more economical choice for many users, especially when compared to plans that only allow a limited data amount.
