Ohayu eSIM Data Plans for Ireland

No, Ohayu does not offer an unlimited data eSIM plan for Ireland. Ohayu provides several fixed‑data options instead. For example, the Ireland 50GB 90 days plan gives 50GB of data for 90 days, the 25GB Monthly plan offers 25GB for 30 days, and the Ireland 20GB 90 days plan supplies 20GB for 90 days; all plans include tethering and use 5G on the network.

Choosing a fixed data plan can be more cost effective for most travelers unless one expects to consume data well beyond the largest plan available, in which case an unlimited option would be preferable—but Ohayu does not currently provide one for Ireland.

Ohayu does not offer Ireland eSIM plans that include a phone number or SMS capability. The provider’s Ireland plans are data‑only, so you will not receive a local phone number or be able to send or receive SMS messages. If you need to make calls or send messages, you can use VoIP apps such as WhatsApp, Telegram or iMessage over the data connection.

Ohayu offers a total of ten data plans that can be used in Ireland, comprising six single‑country plans and four multi‑country plans that include Ireland. The single‑country plans provide fixed data amounts ranging from 2 GB up to 50 GB with prices spanning from about $8.49 to $66.99, while the multi‑country plans typically feature the same data ranges but enable use across several countries in addition to Ireland. Both types of plans can be used for a validity period between 14 and 90 days, and many of them allow tethering to other devices.
