Ovosim eSIM Data Plans for Vietnam

Ovosim does not provide an unlimited data eSIM for Vietnam. All of the available Ovosim plans for Vietnam have a fixed data cap that must be used within a set validity period.

The alternatives are fixed data plans. For example, the Vietnam Plus 60 GB 60 Days plan offers 61 GB of data for 60 days, while the Vietnam 50 GB plan gives 51 GB for 30 days. These fixed data plans can be more cost‑effective unless a traveler requires extremely high data usage.

Ovosim does not offer any eSIM plans for Vietnam that include a local phone number or SMS functionality. Travelers can only purchase data‑only eSIMs from Ovosim for use in Vietnam. Popular VoIP applications such as WhatsApp, Telegram, and iMessage can usually be accessed over the data connection for voice and messaging, but access to these services can be restricted or blocked in certain destinations, so users should confirm that the apps they rely on work in Vietnam before buying a plan.

Ovosim provides 11 single‑country data plans that cover Vietnam and 70 multi‑country plans that include Vietnam in their coverage. The available plans range in price from about $2.99 to $100.81 and offer data caps between 1 GB and 61 GB, with validity periods spanning from 5 to 365 days. Some plans feature a fixed data amount for the entire validity, while others apply a daily data cap that resets each day, giving travelers flexibility depending on their usage patterns.
