CloudOn eSIM eSIM Data Plans for Vietnam

CloudOn eSIM does not provide a truly unlimited data eSIM for Vietnam. The plans that carry the word “Unlimited” in their name actually give a fixed amount of high‑speed data each day (2 GB/day or 3 GB/day) and then reduce the speed to 1 Mbps once that daily allowance is used.

Travelers who need a larger, unthrottled data allowance can choose from CloudOn eSIM’s fixed data plans, such as the 100 GB plan valid for 180 days, the 50 GB plan valid for 30 days, or the 20 GB plan valid for 30 days. These plans provide a set amount of high‑speed data that must be used within the specified validity period.

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.
