MobileSIM eSIM Data Plans for Ireland

MobileSIM does not provide a truly unlimited high‑speed eSIM plan for Ireland. All plans labelled “Unlimited” give 3 GB per day but route traffic to a reduced speed of 1000 kbps once the daily allowance is reached; the plans are technically capped and not unlimited for high‑speed data.

Travelers who require more data can choose from MobileSIM’s fixed‑data options. For example, an Ireland 50 GB eSIM for 30 days costs US$42, while an Ireland 20 GB eSIM for the same period costs US$26. A global 60 GB plan that includes Ireland is available for 125 days at US$165. These fixed plans give a larger data allowance without the speed restriction that applies to the “Unlimited” offers.

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.
