Ireland is in the EU, so a plan from an EU/EEA country should work there at home rates within fair use. If yours is from outside the EU, such as a UK plan, roaming may be charged, so check your terms. The eSIM is worth having if your allowance is small, you work while travelling or you want to protect your own data. It is data only, and your own number stays active.
The plan uses Eir. Coverage is generally good in Dublin, Cork, Galway and the larger towns. Remote parts of the west coast, Connemara, the Kerry mountains and the Aran Islands can be weaker. Note that Northern Ireland is part of the United Kingdom, so EU roaming rules do not cover it. This plan is meant for the Republic of Ireland, and we cannot promise it works in Northern Ireland.
Near the border a phone can switch to a UK network without you noticing, so choose the network manually if you travel close to it. Data helps with public transport apps, maps, ride apps and restaurant bookings. A local SIM means a shop visit, while the eSIM is ready beforehand. Weather changes fast and rural roads are narrow, so keep an offline map for the west coast.
