Ohayu eSIM Data Plans for Singapore

Ohayu does not provide a truly unlimited data eSIM for Singapore. All plans that carry the “Unlimited” name are limited to 3 GB per day; once that amount is reached the network speed is throttled to 1000 kbps. After the daily limit is exceeded the user continues to have access to the eSIM, but the high‑speed data is curtailed.

For travelers who need more predictable high‑speed data, Ohayu offers several fixed data plans. Examples include a 50 GB plan valid for 30 days costing $47.79 USD, a 25 GB monthly plan for $49.49 USD that also covers 104 countries, a 20 GB 30‑day plan for $21.49 USD, a 15 GB monthly plan for $39.99 USD, and a 10 GB 30‑day plan for $14.49 USD. Choosing one of these fixed plans can be more cost effective for most users unless extremely heavy data consumption is expected.

Ohayu does not offer a Singapore eSIM that includes a phone number or SMS capability; the provider sells only data‑only plans for Singapore. Travelers who need voice or text can rely on internet‑based messaging and calling apps such as WhatsApp, Telegram, or iMessage, which work over the data connection without a local phone number.

In Singapore, Ohayu offers eight single‑country data plans and four multi‑country data plans. Plan prices vary from $5.99 to $49.49, while data allowances span from 2 GB to 50 GB. The catalog contains both daily data cap plans—where data usage is limited to a specific amount each day—and fixed data cap plans, which allocate a set amount of data for the entire validity period.
