MobileSIM eSIM Data Plans for Vietnam

MobileSIM does not provide a truly unlimited data eSIM for Vietnam.
The plans that contain “Unlimited” in their name actually limit data to 3 GB per day; once the daily cap is reached, speed falls to 1000 kbps. This means the plans are not high‑speed unlimited, but rather fixed‑data packages with a throttled speed after the limit is hit.

If a user needs larger data allowances, MobileSIM offers fixed‑data plans such as 20 GB for 30 days, 50 GB for 90 days, and 100 GB for 180 days. These are only examples of the fixed‑data options available in Vietnam and represent a subset of the plans that MobileSIM offers.

MobileSIM does not offer eSIM plans for Vietnam that include a local phone number or SMS capability. The provider’s Vietnam eSIM offerings are data‑only, with no inbound or outbound voice or text services. Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to place calls and send messages.

MobileSIM offers 12 single‑country plans and 22 multi‑country plans for Vietnam. The available packages span a price range from $1.50 to $89.00 USD, with data caps from 200 MB up to 100 GB and validity periods between 3 and 180 days. Plans are grouped into daily data cap options, which limit usage each day, and fixed data cap options, which provide a set amount of data for the entire validity period.
