What to know about mobile data in Ireland

Ireland is in the EU roaming area. Northern Ireland is part of the UK, which is not. The land border is open, and phones on either side pick up the other jurisdiction's networks, a problem the two regulators have examined together. On the network side, Vodafone closed 3G in October 2024 and Eir began retiring its 3G county by county on 1 October 2026, starting in Donegal. 2G stays on, so older phones keep calls and lose usable data.

Before you go

  • Driving through Donegal, Monaghan or Louth? Select an Irish network manually if your plan does not include the UK.
  • Visiting Belfast or the Giant's Causeway from Dublin is a trip to the UK. Confirm the United Kingdom is in the plan.
  • On the west coast, signal is weakest on headlands and islands. Download maps before a day on the peninsulas.

Yes. 7 of the providers we track sell unlimited plans for Ireland; the cheapest is Holafly at $3.90 for 1 day. Unlimited plans often slow down after a daily amount, so read the fair-use note on the provider page.

Which regional eSIM plans include Ireland?

26 of the 69 regional and global products we track list Ireland: Ubigi Europe, Nomad Europe (35 countries plan), Yesim Europe & UK, Holafly Europe, Saily Europe Unlimited (35 countries), Airalo EUconnect (European Union and United Kingdom), Saily Europe (34 countries), Airalo Eurolink.

Does an Ireland eSIM work in Northern Ireland?

Only if the plan also names the United Kingdom. Northern Ireland uses UK networks, and the UK left the EU roaming regime, so a plan for Ireland or for EU countries does not extend there by default.

Why does my phone show a UK network while I am still in the Republic?

That is inadvertent roaming. Near the border, a mast on the other side can be the strongest signal, and the phone attaches to it without you crossing. Manual network selection stops it.
