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 provide an eSIM plan for Ireland that includes a phone number or SMS capability. Only data‑only eSIMs are available from the provider. Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging.

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.
