Firsty eSIM Data Plans for Vietnam

Firsty does provide an unlimited data plan for Vietnam with a 1‑day validity. The plan, called Firsty Free, is offered at no cost and includes advertising. Because the data allowance is unlimited, speeds can be throttled; the highest stated bandwidth is 256kbps, and normal speed may be reduced after heavy usage under a fair‑usage policy. If you need clarification on how long normal speed is maintained or whether the plan includes any other speed restrictions, you should contact Firsty directly for the most up‑to‑date details.

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.

Firsty offers a total of 17 data plans for travelers in Vietnam, split between single‑country and multi‑country options. In Vietnam customers can choose from 16 different single‑country plans that range in price from free up to approximately $69, with data caps that start at 1.5 GB and extend up to unlimited data. The sole multi‑country plan covers several destinations outside Vietnam, falls within the same overall price band, and also includes data caps from 1.5 GB to unlimited. The catalogue contains both fixed‑amount plans—3 of them which provide a set data volume for a fixed period—and daily‑cap plans—14 of them that limit the daily data usage to ensure consistent speeds. Prices and data limits vary across the 17 offerings, giving travelers a broad choice of options depending on length of stay and data needs.
