Ohayu eSIM Data Plans for Singapore

Ohayu does not provide an unlimited data eSIM for Singapore. The available plans offer fixed data allowances, including options such as 50GB for 30 days at $54.79 USD, 25GB for 30 days at $49.49 USD, 20GB for 30 days at $24.49 USD, 15GB for 30 days at $39.99 USD, and 10GB for 30 days at $16.79 USD. These plans cover Singapore and, in the case of the 25GB and 15GB options, extend coverage to 105 additional countries. Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user is an extremely heavy data consumer who might prefer an unlimited plan.

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 has 5 single‑country plans available for Singapore, covering local data usage only, and 4 multi‑country plans that include Singapore as part of a broader regional package. The plans range in price from $6.99 to $54.79 USD and offer data caps between 2GB and 50GB, with validity periods spanning 15 to 30 days. Some of the plans also allow tethering.
