MobileSIM eSIM Data Plans for Ireland

MobileSIM does not offer a truly unlimited data eSIM plan for Ireland. The plans that carry the word “Unlimited” in their name actually provide a fixed high‑speed data allowance of 3 GB per day; once that limit is reached the connection speed is reduced to 1000 kbps. Because of this throttling, no plan gives unlimited high‑speed data for the entire validity period.

MobileSIM does provide fixed‑data plans instead. For instance, a 50 GB plan for 30 days is priced at $42.00, and a 60 GB plan valid for 125 days costs $165.00. These plans deliver a set amount of high‑speed data and can be more cost‑effective unless a user requires an extremely large volume of data.

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.
