eSIM Travel Tips for Ireland
Ireland uses euro, a handy reminder
The Republic of Ireland uses the euro, not the pound. As a British visitor crossing from Northern Ireland or flying from a UK airport, remember to change currency. Your HelloRoam eSIM cost is fixed in dollars at purchase so there are no euro-related surprises on your data bills.
Driving on rural Irish roads
Ireland has a famously narrow country road network. Signal on main N-roads and motorways is generally good. Remote lanes through Connemara, the Dingle Peninsula, Donegal, and the Burren can have limited 4G coverage. Download offline maps of your driving routes before venturing off main roads.
Wild Atlantic Way connectivity
The Wild Atlantic Way stretches from Donegal to Cork along the west coast. Coastal towns and villages like Westport, Clifden, Doolin, and Dingle have reasonable 4G. Very remote cliff-top lookout points and sea stacks far from settlements may have weak or no signal. Download your route map and points of interest before heading out.
No GHIC needed in Ireland
British citizens are entitled to healthcare in Ireland under a reciprocal arrangement separate from the GHIC scheme. Keep your HelloRoam eSIM connected to locate Irish pharmacies, HSE walk-in centres, or contact your travel insurer if needed.
Keep your UK number active for banking
Your UK bank may send SMS codes to your British number. Keep your UK SIM active whilst using HelloRoam for Irish data. You remain reachable on your UK number for calls and security verification throughout your stay in the Republic.
