MobileSIM eSIM Data Plans for Vietnam

MobileSIM does not have a true unlimited data eSIM for Vietnam. The plans that carry the “Unlimited” name provide 3 GB per day for the specified validity period; once the daily allowance is reached, the speed is reduced to 1000 kbps.

Travelers who need higher or continuous data can choose a fixed‑data plan instead. For example, MobileSIM offers a 20 GB plan for 30 days at $30.50 or a 100 GB plan for 180 days at $185.00. These fixed‑cap plans supply 4G/5G data without the post‑limit throttling, and may be more cost‑effective for heavy data users.

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 provides 12 single‑country data plans and 13 multi‑country data plans for use in Vietnam. The provider offers both fixed‑data‑cap plans and daily data‑cap plans; fixed‑cap plans give you a set amount of data (up to 100 GB) for the entire validity period, while daily data‑cap plans allow a limited amount of data each day (up to 6 such plans). Prices for the Vietnam‑specific plans range from about $4 to $185, with data caps ranging from 1 GB to 100 GB over validity periods spanning 3 to 180 days.
