Coverage in Ireland

Rural western regions (Connemara, parts of Donegal, Kerry) have large areas with no service on any network. No operator runs a 3G-only network; all have shut down 3G or are in the process. Band B28 (700 MHz) is used by Three and Eir but is absent from some North American phone variants.

Common Questions

The details worth knowing about your Ireland eSIM

This eSIM is for the Republic of Ireland only. Mobile networks in Northern Ireland are operated by UK providers, not by Vodafone, Three, or Eir. Your data will not roam across the border. Consider a separate UK eSIM if you cross into Northern Ireland.

Three and Eir use band B28 (700 MHz) for 4G, which travels farther in rural areas like Connemara or Donegal. Many North American phone variants lack B28. If your phone does not support B28, you may have similar coverage gaps to Vodafone users in these western regions.

Your eSIM will automatically select a partner network, typically based on signal strength. You cannot manually choose which operator to connect to. The eSIM may latch onto any of the three networks: Vodafone, Three, or Eir, depending on availability at your location.

5G is available on networks n3 (1800 MHz) and n78 (3500 MHz), which all three operators—Vodafone, Three, and Eir—support. Whether you get 5G depends on your phone’s compatibility with these bands and your proximity to a 5G tower. No 5G coverage exists in many rural western areas.

No registration or ID is required to use this eSIM in Ireland. Irish law does not mandate personal identification for prepaid mobile data services. You simply install the eSIM and activate it. No passport or local registration steps are needed.
