eSIM for Ireland — Instant 4G/5G Data Plans

Ireland's mobile network is served by three main operators: Vodafone Ireland, Three Ireland, and Eir. 4G LTE coverage is comprehensive across Dublin, Cork, Galway, Limerick, and all major cities, with strong connectivity along main road and rail corridors. The Wild Atlantic Way coastal route, Ring of Kerry, and Connemara have coverage in towns and villages, though more remote coastal headlands, mountain areas including MacGillycuddy's Reeks, and island communities such as the Aran Islands may have weaker signal. Rural areas of the west and northwest, including parts of Mayo, Donegal, and Kerry, can have inconsistent coverage away from main settlements. MobiSIM connects through supported Irish networks to deliver reliable data across Ireland's main cities and tourist routes.

Install your MobiSIM eSIM before landing at Dublin Airport or Cork Airport so you are connected from arrival. Download offline maps for the Wild Atlantic Way, Ring of Kerry, Connemara, and Donegal before setting out on coastal drives, as clifftop and remote headland areas can have inconsistent signal. Keep your home SIM active for calls while MobiSIM handles your data. Ireland's bus and rail network connects main cities and having live data for Irish Rail and Bus Éireann schedules makes intercity travel straightforward. If you are taking a ferry to the Aran Islands, visiting Skellig Michael, or driving remote Donegal peninsulas such as the Inishowen or Dingle, save all maps, accommodation details, and boat schedules offline before departing the nearest town with reliable coverage.
