Best eSIM for Ireland

Ireland has three networks — Vodafone, Three and Eir — with good coverage in Dublin, Cork, Galway and other towns. Coverage gets patchy on the Wild Atlantic Way, in Connemara, Kerry and Donegal. And Northern Ireland is in the UK, not the EU, which catches out a lot of travellers.

At a glance

  • Budget pick: Talisim — $8.56 for 10 GB / 30 days on Eir, with no account needed
  • Two networks: Nomad — $16 on Three and Eir
  • Best for Ireland plus the UK: Airalo Eurolink — covers both the Republic and Northern Ireland, so you don’t lose data crossing the border
  • Best for unlimited data: Holafly Ireland — from $27.50 for 7 days, but hotspot is capped at about 500 MB–1 GB a day
  • For rural road trips: Dracotel — lets you switch between Vodafone, Three and Eir from your phone’s network settings, which helps on the west coast where coverage swaps between networks. From about $0.65 per GB, plus a $12-a-year subscription

Network notes

Vodafone and Three have the widest coverage, with Eir close behind. In the west and north-west, each network has its own dead spots, so a valley with no Eir signal may have Vodafone, and the other way round.

Talisim’s Ireland plan runs only on Eir, and Airalo’s only on Three. That’s fine for cities and most towns. For a long road trip around the coast, a plan that can use more than one network is safer: Nomad’s uses Three and Eir, and Dracotel can switch between all three networks.

Practical connectivity tips

  • Install before you land. Dublin airport Wi-Fi is free, but you’ll want data for the bus or a taxi into the city.
  • Apps you’ll want online: FREENOW (the main taxi app in Ireland), Uber (which books licensed taxis here), TFI Live (public transport), Irish Rail, and Google Maps.
  • Download offline maps for the Ring of Kerry, the Dingle Peninsula and Connemara.
  • Ferries to the Aran Islands and boat trips to Skellig Michael lose signal at sea.

Watch out for

  • Northern Ireland is in the UK. EU-only plans may not work there, and UK-only plans won’t work in the Republic. Near the border your phone can also connect to a UK network without you noticing. Choose a plan that covers both if you’re crossing.
  • Rural Donegal, Mayo and Kerry have the weakest coverage.
  • Pubs and B&Bs in the countryside often have slow Wi-Fi.
