How to choose the right plan
- Light use — maps, messaging and browsing — needs about 1 GB per day.
- Heavy use — social video, streaming or hotspotting a laptop — plan for 2-3 GB per day or pick the largest plan.
- Match the validity to your trip length, with a day or two of buffer for delays.
How activation works
- Buy the plan and receive your eSIM by email within minutes.
- Install it from your phone settings while still at home — no store visit, no plastic SIM.
- Land in Ireland, enable the eSIM line, and you are online before leaving the airport.
All Ireland eSIM plans
Maps on a hedge-lined road, a bus time in a village, and a pub that does not list an address a robot can find: you want data. An eSIM is online at Dublin Airport before you reach the rental-car desk.
If you are also crossing to Northern Ireland, check the plan. Some UK and Ireland plans cover both; country-only ones do not always agree with the border.
