Ohayu eSIM Data Plans for Vietnam

Ohayu does not provide an unlimited data eSIM for Vietnam. All of its Vietnam plans have a fixed data allowance. For travelers who need a large data quota, Ohayu offers, for example, a Vietnam 50GB 90 days plan and a 25GB Monthly plan. Choosing a fixed data plan can be more cost‑effective unless the user is an extremely heavy data consumer who would prefer an unlimited option.

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.
