Ohayu eSIM Data Plans for Australia

Ohayu’s plans that carry the name “Australia Unlimited” provide 3 GB per day for the duration of the plan, but they are not truly unlimited in the high‑speed sense. After the 3 GB daily allowance is used, the data speed is throttled to 1000 kbps. Consequently, Ohayu does not offer a fully unlimited data eSIM for Australia.

Instead, Ohayu offers several fixed‑data options that can be more cost‑effective for heavy users. For example, a 50GB plan is available for 30 days at $62.49 USD, and a 20GB plan for 30 days costs $27.79 USD. These fixed‑data plans avoid the speed reduction that occurs on the “Unlimited” plans and can be a better choice for travelers who need a large amount of high‑speed data.

Ohayu does not provide eSIM plans for Australia that include a phone number or SMS capability. Customers can only purchase data‑only plans from this provider for the Australian market. If you need voice or text services, you can rely on popular VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection and do not require a local phone number.

Ohayu offers ten single‑country plans and four multi‑country plans that include Australia.
The single‑country options provide between 2 GB and 50 GB of data, valid for 5 to 60 days, with prices ranging from $7.49 to $62.49.
The multi‑country plans cover the same data and validity ranges, with the same price band, offering a broader geographic coverage while keeping the same core features.
