Ohayu eSIM Data Plans for Singapore

Ohayu does not currently offer an unlimited‑data eSIM plan for Singapore. Travelers who need more data can choose from the fixed‑data options that Ohayu provides. For example, the Singapore 50GB plan is valid for 30 days and costs $54.79 USD, while the Singapore 25GB plan also has a 30‑day validity for $49.49 USD. Larger data allowances can be found in other fixed plans, such as the 20GB, 15GB, and 10GB options, all valid for 30 days. Selecting a fixed‑data plan may be more economical unless a user requires truly unlimited usage.

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.

Ohayu offers eight data plans that cover Singapore, split between single‑country and multi‑country options. Five of the plans are single‑country, dedicated exclusively to Singapore, while four plans package Singapore data with coverage in other destinations. The available plans provide data caps from 2 GB up to 50 GB, with prices ranging from about $6.99 to $54.79 depending on the validity period of 15 to 30 days. Some of the plans also allow tethering, giving users flexibility to share the data with multiple devices.
