Firsty for Vietnam FAQ
Does Firsty offer unlimited data eSIM for Vietnam?
Firsty does not offer an unlimited data eSIM plan for Vietnam. All of the plans sold for this destination provide a fixed amount of data, such as the Firsty First Class 1 day plan, which delivers 8 GB, or the 5 day plan, which delivers 8 GB per day. These fixed‑data options can be more economical for most travelers unless an extremely high data usage is expected.
Does Firsty offer Vietnam eSIM with phone number and SMS?
Firsty does not offer a Vietnam eSIM plan that includes a local phone number or SMS capability. Only data‑only eSIMs are available for travelers in Vietnam from this provider.
Customers can still use the data portion of their eSIM to access VoIP applications such as WhatsApp, Telegram, and iMessage, which allow voice calls and messaging over the internet without a native phone number.
How many data plans does Firsty offer for Vietnam?
Firsty provides 16 single‑country data plans for Vietnam, with no multi‑country options available. Among these, 14 plans use a daily data cap that resets each day, while 2 plans offer a fixed data amount that does not reset daily. Prices for the Vietnamese plans range from about $1.78 to $71.25, and data caps span from 1.5 GB up to 8 GB. The daily‑cap plans allow you to pull a set amount of data each day, which can be useful for short‑term travelers who want predictable daily usage, whereas the fixed‑cap plans give you a lump sum of data that remains available for the entire validity period.
