Ovosim eSIM Data Plans for Vietnam

Ovosim does not have a plan that provides truly unlimited high‑speed data for Vietnam. All of its Vietnam offerings have a fixed data allowance, such as the 51GB 180‑day plan, the 20GB 30‑day plan, or the various “Unlimited” named plans that actually supply a capped amount of data per day before the speed is reduced. Travelers who need a large amount of data can choose one of these fixed‑data plans, which may be more cost‑effective for most uses.

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 offers 39 single‑country plans and 58 multi‑country plans for Vietnam. The available plans range in price from $4.54 to $113.90 and provide data caps between 1 GB and 51 GB. Some plans feature a daily data cap that resets each day, while others offer a fixed data cap that is available for the entire validity period.
