MobileSIM eSIM Data Plans for Ireland

MobileSIM does not provide a truly unlimited data eSIM for Ireland. The plans labeled “Ireland Unlimited data for X days” give a daily allowance of 3GB; once that limit is reached the speed is throttled to 1000kbps.

Travelers who need more data can choose from MobileSIM’s fixed data plans for Ireland, such as the 50GB for 30 days, the 20GB for 30 days, or the 10GB for 30 days options. These plans offer larger total data allowances without the daily cap and speed reduction.

MobileSIM does not offer eSIM plans for Ireland that include a phone number or SMS capability. The only plans available are data‑only options.

Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. Some destinations, however, may limit access to certain apps or VoIP services, so it is advisable to confirm that the applications you rely on are accessible in Ireland before purchasing a MobileSIM eSIM.

MobileSIM offers 13 single‑country plans and 10 multi‑country plans for use in Ireland. The price range spans from roughly $2.30 to $165, with data limits between 200 MB and 60 GB and validity periods ranging from 3 to 125 days. Among the plans, six employ a daily data cap, limiting the amount of data available each day, while 17 use a fixed data cap that provides a set total amount of data for the entire validity period.
