MobileSIM eSIM Data Plans for Vietnam

MobileSIM does not provide a truly unlimited eSIM plan for Vietnam. All “Unlimited” options listed in the catalogue give a daily limit of 3 GB. After that limit is reached, the connection speed is throttled to 1000 kbps, so the data is not high‑speed and unlimited. Travelers who need more straightforward data coverage can choose from several fixed‑data plans that are flat‑rate, such as the 20 GB plan valid 30 days or the larger 100 GB plan valid 180 days. These options offer the same network speed throughout their validity without the speed reduction that applies after the daily 3 GB limit of the “Unlimited” plans.

MobileSIM does not provide eSIM plans for Vietnam that include a local phone number or SMS capability. All eSIM offerings from MobileSIM for Vietnam are data‑only and do not support inbound or outbound voice calls or text messages.

Travelers who need voice or text communication can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, access to these services is not guaranteed, as some destinations may block or restrict specific apps. Users should verify that the apps they rely on are available in Vietnam before purchasing a plan.

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.
