Frequently Asked Questions
Does Firsty offer unlimited data eSIM for Vietnam?
Firsty offers an unlimited data eSIM for Vietnam called Firsty Free. The plan provides unlimited high‑speed data for 1 day and is free of charge, $0.00 USD. It includes advertising and the plan’s speed may be throttled; the maximum speed is capped at 256kbps.
Because the plan is unlimited, it is subject to a Fair Usage Policy that may reduce speeds after heavy usage. Travelers who are concerned about potential speed restrictions are encouraged to contact Firsty directly to confirm whether the policy applies and to learn the typical amount of data that can be used at normal speed.
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 lists 16 single‑country plans that cover only Vietnam and one multi‑country plan that includes Vietnam among other destinations. The available plans range in price from free to roughly $69.64 and provide data caps from 1.5 GB up to unlimited, with some options featuring a daily data cap and others offering a fixed data amount for the entire validity period. The single‑country selection includes both daily‑cap and fixed‑cap variations, while the multi‑country option is designed to offer a broader data allowance that extends beyond Vietnam alone.
