Ohayu eSIM Data Plans for Cambodia

Ohayu does not provide a truly unlimited data eSIM for Cambodia. All plans that contain “Unlimited” in their name actually grant 3 GB per day and after that daily limit is reached the speed is throttled to 1000 kbps. The label “Unlimited” is therefore misleading; the plans have a fixed data cap.

Travelers who need more data can choose one of Ohayu’s fixed‑data plans. For example, the 50 GB plan valid for 90 days or the 25 GB monthly plan give larger high‑speed data allowances and do not impose a speed cut‑off once the data cap is reached. These options are available for Cambodia and may be a more cost‑effective choice for heavy users.

Ohayu does not provide an eSIM for Cambodia that includes a local phone number or SMS capability. Only data‑only plans are available from this provider for travelers in Cambodia.

Without a phone number or SMS, callers can instead rely on internet‑based VoIP applications such as WhatsApp, Telegram and iMessage to make voice and text communications over the data connection.

Ohayu provides 9 single‑country plans and 4 multi‑country plans for Cambodia, covering a price range of $8.49 to $128.49 and data caps between 2 GB and 50 GB. Plan validity varies from 5 to 90 days, and there are 10 fixed‑data‑cap options alongside 3 daily‑data‑cap options, allowing travelers to choose whether they want a set amount of data or a daily allowance.
