Ohayu eSIM Data Plans for Vietnam

Ohayu does not offer an unlimited data eSIM plan for Vietnam. Travelers looking to stay connected can select from a range of fixed data allowances, such as the Vietnam 50GB 90 days plan or the 25GB Monthly plan, both of which include tethering and operate on 5G networks.

Choosing a fixed data plan is often more economical for most users; however, if a traveller is an extremely heavy data consumer, a different carrier or a higher‑cap plan may be more appropriate.

Ohayu does not provide a Vietnam eSIM that includes a phone number or SMS capability. The provider offers only data‑only plans for use in Vietnam. Travelers who need voice or messaging can use popular VoIP applications such as WhatsApp, Telegram or iMessage over the data connection.

Ohayu offers six single‑country data plans that cover only Vietnam, and four multi‑country plans that include Vietnam among other destinations. The plans vary in price from about $9.49 to $76.79 and in data volume from 2 GB up to 50 GB, with validity periods ranging from 15 to 90 days. Most of these plans deliver a fixed data allowance (for example, a 20 GB bundle for 30 days), and a few offer the ability to set a daily data cap, allowing users to control how much data is usable each day. Tethering is permitted on several of the plans, enabling the device to share the internet connection with other devices.
