Ohayu eSIM Data Plans for East Asia

Ohayu does not provide an unlimited data eSIM plan for East Asia. Travelers can instead choose from a range of fixed‑data plans. For example, Ohayu offers a 25GB Monthly plan and a 15GB Monthly plan, each valid for 30 days and covering China, Hong Kong, Japan, South Korea, Macau, Taiwan, plus more than 100 other countries. These fixed‑data options often prove more cost‑effective for most users, unless very heavy data consumption is required, in which case heaviest‑topping plans may be more suitable.

No, Ohayu does not provide an East Asia eSIM that includes a phone number or SMS capability. Ohayu offers only data‑only eSIM plans for this region. Travelers can still use voice and messaging applications such as WhatsApp, Telegram, and iMessage over the data connection, but there is no traditional dialing code or SMS service included with the plan.

The Ohayu Monthly eSIM plan offers coverage in several East Asian countries, specifically China, Hong Kong, Japan, South Korea, Macau, and Taiwan. In addition to this plan, Ohayu also provides other eSIM options that extend beyond East Asia, covering regions across Europe, the Americas, and the Middle East.
