RoamGo eSIM Data Plans for Vietnam

No, RoamGo does not offer an unlimited data eSIM plan for Vietnam. The largest data allowance available is 50GB, which is valid for 180 days in the Vietnam 50GB 180Days plan. Other fixed data options include a 20GB plan that is valid for 30 days and covers Vietnam along with several neighboring countries.

Because these are fixed data plans, they have clear data limits. For most travelers a fixed plan can be more cost‑effective unless the user expects to consume far more data than the plan’s allowance, in which case a different provider or a pay‑as‑you‑go option would be necessary.

RoamGo does not offer a Vietnam eSIM that includes a phone number or SMS capability. The provider’s plans for Vietnam are purely data‑only. Travelers who need voice or text service can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should check whether these apps are accessible in Vietnam before purchasing, as some destinations may block or restrict certain services.

RoamGo provides 42 single‑country plans and 141 multi‑country plans that include Vietnam. The plans span a price range from $0.77 to $438.75 and offer data caps between 500 MB and 50 GB, with validity periods from 1 to 365 days. Some plans are fixed‑data‑amount plans, while others use a daily data cap, giving travelers flexibility depending on their usage patterns.
