Frequently Asked Questions
Does Firsty offer unlimited data eSIM for Vietnam?
Firsty does not provide an unlimited‑data eSIM plan for Vietnam. Instead, the provider offers fixed data plans that give 8GB per day for the validity period. For example, a 3‑day plan delivers 8GB/day for $7.80 USD, and a 10‑day plan delivers 8GB/day for $24.81 USD. Choosing a fixed data plan can be more cost‑effective unless a traveler requires a truly unlimited data allowance.
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 eSIM plans for Vietnam, with no multi‑country options available. Among those, 14 plans use a daily data cap while 2 offer a fixed data amount for the entire validity period, giving travelers flexibility depending on their usage patterns. Prices span from approximately $1.77 to $70.89, and data caps range from 1.5GB up to 8GB, with validity periods ranging from one day to thirty days, allowing users to pick a configuration that fits their stay and budget.
