Why Get an eSIM for Ireland?
- Navigate country roads with live maps and traffic.
- Online from the arrivals hall, ready for the bus into Dublin or your rental car.
- Keep your number for bank codes and messages from home.
- Avoid roaming fees if your carrier is outside the EU.
How to Choose an Ireland eSIM
Trip length
Pick a plan that covers your whole stay plus a spare day for flight times. egoViet plans can't be topped up, so it is better to size up than to run short. If your high-speed data does run out, you stay online at a basic speed of around 128 kbps, enough for messaging.
How much data you use
Maps and messages use little data. Video calls, streaming, and uploading photos from the cliffs use much more. Here is a guide to how much data you need when you travel.
Where you are going
For the Republic of Ireland alone, an Ireland eSIM is the best value. Crossing into Northern Ireland or continuing to Great Britain? See the Europe eSIM below.

How to Set Up Your Ireland eSIM
- Check your phone is eSIM-compatible and carrier-unlocked. See our eSIM compatibility list.
- Buy your plan. The QR code arrives by email within minutes.
- Install it at home on Wi-Fi with our installation guide.
- When you land in Ireland, switch the eSIM on, set it for mobile data, and turn on data roaming for that line. Keep data roaming off on your home SIM.
Tips for Staying Connected in Ireland
- Download offline maps for the West Coast. Signal can be weak in Connemara, on the Dingle Peninsula, and on some islands.
- Use a Leap Card or contactless for Dublin buses, Luas trams, and DART trains.
- Check the weather often. Conditions change quickly, especially on cliff walks.
- Remember the border. Your Ireland eSIM may lose coverage once you cross into Northern Ireland.
- Need to call? egoViet eSIMs are data-only, so use WhatsApp or FaceTime. Here is how calling works with a data-only eSIM.
