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 provides a mix of single‑country and multi‑country eSIM offerings when traveling to Singapore. There are six single‑country plans and four multi‑country plans available for Singapore. The price spectrum ranges from $0.49 to $54.79, while data allowances span from 1 GB up to 50 GB and validity periods vary between 1 and 30 days. Some plans also support tethering and are restricted to new users only.
