Your Ireland eSIM in two questions
Which Ireland eSIM plan do I need?
Dublin weekends, Killarney road trips and month-long stays all need different amounts of data, so start with how long you're going.
- A city break in Dublin: three days of maps, messages and a few rides suit 1 GB a day for 3 days.
- A fortnight touring Ireland: from Cork to Galway, Killarney and Dingle, pick 10 GB for 30 days for standard use.
- A month-long stay: 20 GB for 30 days suits standard use for the whole visit.
- A week that crosses the border: near Northern Ireland, your phone may switch to a UK network without warning. For a week of standard use, the UK & Ireland eSIM with 5 GB for 30 days fits.
Most plans can be topped up, so you can add more data mid-trip if you need it.

These eSIMs cover Ireland and more countries on one plan.
Will my eSIM have signal in Ireland?
Your eSIM joins Eir, and Eir runs 5G, so your phone uses it wherever 5G is on offer. Cities, towns and main roads are well covered, while signal can be patchy in remote western and mountain areas. Your phone picks the network by itself, so there is nothing to set up once you land.
- Near the border with Northern Ireland, your phone may switch to a UK network without warning.
- Your data reaches the internet through France, the Netherlands or the United Kingdom, a normal setup for travel eSIMs. Read more on IP addresses in other countries.
- Daily plans slow down to 512 Kbps once you've used that day's allowance.
