Ohayu eSIM Data Plans for Ireland

Ohayu does not provide a truly unlimited data eSIM for Ireland. All plans that carry the “Unlimited” label supply a 3GB per day allowance; after this cap the data speed is throttled to 1000kbps.

Travelers who need more data can select from Ohayu’s fixed‑data plans, such as the 50GB 90‑day option, the 25GB monthly plan, or the 20GB 90‑day plan. These high‑capacity plans can be more cost effective for most users unless very heavy data consumption is expected.

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 fourteen data plans that are available for Ireland. Ten of those are single‑country options tailored to use within Ireland, while four plans cover multiple countries and include Ireland as part of a wider regional package. The available plans range in price from about $0.49 to $58.49 and in data allowance from 1 GB up to 50 GB, with validity periods spanning one to ninety days. Among the single‑country plans, some provide a fixed data amount that does not change day to day, whereas four of them apply a daily data cap that replenishes each day, offering a different consumption model for travelers who need predictable daily usage.
