MobiMatter eSIM Data Plans for Ireland

MobiMatter does not provide a truly unlimited data eSIM for Ireland. All of its offers have fixed data caps—ranging from 20 GB to 120 GB—with the advertised “Unlimited” in the name referring only to call and text freedom. After the data ceiling is reached, no reduced‑speed clause is specified, so the plan ceases to provide additional high‑speed data. Travelers who require more data can choose from large fixed‑data options such as the 120 GB plan valid for 30 days or the 60 GB plan valid for 30 days, both covering Ireland and many other European countries. Selecting a fixed data plan is usually more cost‑effective unless the user is an extremely heavy data consumer.

MobiMatter does not offer an eSIM plan with a local phone number or SMS capability for travelers in Ireland. The provider’s available plans for Ireland are data‑only, so if you need to make calls or send text messages you would use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

MobiMatter offers 57 multi‑country data plans that include coverage in Ireland, but no single‑country plans are available for that country.
These plans range in price from about $3.49 to $74.99 and provide a data cap from 1 GB up to 200 GB. Validity periods span from 7 days to a full year, and many of the options allow tethering to other devices.
