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 data plans that cover only Vietnam and 22 multi‑country plans that include Vietnam. The available plans span a price range from roughly US $2.34 to US $89 and a data volume that can be as low as 200 MB or as high as 100 GB. Some plans lock in a daily data cap, while others provide a fixed data amount for the entire validity period.
