CloudOn eSIM eSIM Data Plans for Vietnam

CloudOn eSIM does not provide a true unlimited‑data eSIM for Vietnam. The plans that list “Unlimited” in their names actually offer a fixed amount of high‑speed data per day (2GB/day or 3GB/day) and, after that limit is reached, the speed is throttled to 1000kbps. These plans are not truly unlimited.

Instead, CloudOn offers fixed data plans with larger data allowances for travelers who need more continuous high‑speed usage. For example, a 20GB plan valid for 30 days or a 50GB plan valid for 30 days are available. A 100GB plan valid for 180 days is also offered. These fixed plans can be more cost‑effective for heavy data users.

CloudOn eSIM does not provide a phone number or SMS capability for Vietnam. The provider offers only data‑only eSIM plans for travelers to the country. Travelers can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, but such apps may be blocked or restricted by Vietnam, so it is advisable to verify their availability before purchasing.

CloudOn offers 18 single‑country plans and 31 multi‑country plans for travelers heading to Vietnam. The available plans range in price from $3.49 to $126.99 and provide between 500 MB and 100 GB of data, with validity periods ranging from 3 to 180 days. Within these options, 18 plans feature a daily data cap, while the remaining 31 plans offer fixed data amounts.
