Astaroam eSIM Data Plans for Vietnam

Astaroam does not offer a truly unlimited data eSIM for Vietnam; all plans listed use a fixed 3 GB/day cap and, after that limit is reached, the speed is reduced to 1000 kbps. Travelers looking for more data can choose a fixed‑data plan instead. For example, the 50 GB plan valid for 90 days or the 20 GB plan for 30 days give larger allowances and may be more cost‑effective for heavy‑data users, though the network speed on the device remains the same as the standard service.

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.
