Frequently Asked Questions
Does Firsty offer unlimited data eSIM for Vietnam?
Firsty does not provide an unlimited data eSIM plan for Vietnam. The available plans are fixed‑data packages, each offering 5 GB of high‑speed data per day for a specified validity period. For example, a 10‑day plan delivers 5 GB per day at a price of $24.37 USD. These fixed plans may be more economical for most travelers, unless the user is an extremely heavy data consumer who would otherwise prefer an unlimited arrangement.
Does Firsty offer Vietnam eSIM with phone number and SMS?
Firsty does not provide a phone number or SMS capability for Vietnam eSIMs. Only data‑only plans are offered by the provider. Travelers can still use VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging.
How many data plans does Firsty offer for Vietnam?
Firsty offers 16 single‑country data plans for Vietnam, with no multi‑country plans available. Among those, 14 plans feature a daily data cap—meaning the set amount of data is refreshed each day of validity—while 2 plans provide a fixed data cap that covers the entire validity period. Prices span from about $1.74 up to $69.62, data caps range from 1.5 GB to 5 GB, and validity periods vary from 1 to 30 days.
