MobileSIM eSIM Data Plans for Ireland

MobileSIM does not offer a truly unlimited high‑speed data eSIM for Ireland. The plans labeled “Unlimited” provide 3GB per day and reduce speed to 1000 kbps once that threshold is reached, so the data is capped. If a traveler needs a larger, capped allowance, MobileSIM offers fixed‑data options such as 20 GB for 30 days or 50 GB for 30 days. These fixed plans can be more cost‑effective unless the user requires continuous, unconstrained data usage.

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.
