Ohayu eSIM Data Plans for Vietnam

Ohayu does not offer an unlimited data eSIM plan for Vietnam. The catalog contains only fixed data plans, such as the 50GB 90‑day option and the 25GB monthly plan, both of which provide large data allowances that may be more cost‑effective for most travelers. Those looking for unlimited data would need to seek alternatives from other providers.

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 and four multi‑country plans that include Vietnam. The single‑country options range from small, inexpensive bundles with caps as low as 1 GB to larger packages up to 50 GB, with prices starting near $0.49 and rising toward $76.79 for the highest‑value items. Multi‑country bundles cover Vietnam alongside other destinations, offering similar data ranges and pricing, with validity periods spanning from one day to ninety days. Some plans feature a fixed data amount while others allow daily usage limits, giving travelers flexibility depending on their needs.
