Astaroam eSIM Data Plans for Vietnam

Astaroam does not provide a truly unlimited high‑speed eSIM for Vietnam. The plans marketed as “Unlimited” actually give a 3 GB daily allowance; after the limit is reached the speed is reduced to 1000 kbps.

Travelers who need larger data packages can instead opt for fixed‑data plans such as 20 GB for 30 days or 50 GB for 90 days. These options offer more data at a single rate and can be more cost‑effective for heavy data users.

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.
