Astaroam eSIM Data Plans for Vietnam

Astaroam does not provide a fully unlimited high‑speed data eSIM for Vietnam. Their plans that include “Unlimited” in the name actually cap the data at 3GB per day, and after that limit the speed is throttled to 1000kbps. If travelers need larger amounts of high‑speed data, fixed‑data options are available, such as 50GB for 90 days and 20GB for 30 days, which maintain full speed throughout their validity.

Astaroam does not provide a Vietnam eSIM that includes a local phone number or SMS capability. The company offers only data‑only eSIM plans for Vietnam. Travelers can still use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but some destinations may block or restrict access to certain apps, so users should verify that the services they rely on are available in Vietnam before purchasing.

Astaroam offers 10 single‑country data plans and 26 multi‑country data plans for use in Vietnam. The plans cover a price range from about $2.74 to $48.75, with data caps varying from 500 MB up to 50 GB and validity periods between 3 and 90 days. Of the single‑country options, 10 plans are based on a daily data cap, while all 26 multi‑country plans use a fixed data cap, allowing travelers to choose between daily‑reset data and a set amount of data for the entire validity period.
