How this map is built
Antenna azimuths are not published for Ireland: coverage is drawn as circles around each site.
0% of the sites have a published antenna height; the model assumes 35 m elsewhere.

Frequently asked questions about Three coverage
Does Three have good coverage in Ireland?
Coverage changes from one street to the next, so the answer depends on where you are. Search your own address on the map above to see the Three signal there.
Does Three offer 5G in Ireland?
Yes. Three runs 5G from 1,874 of its sites. Switch the map to 5G to see the covered areas.
Is the Three map up to date?
The map is built from antenna data dated October 2026, and the Three network facts were last verified on August 14, 2026. Sogudo does not resell Three data. Coverage accounts for each antenna's sectors, the terrain between you and the antenna, and the density of the built environment around it.
Is Sogudo affiliated with Three?
No. Sogudo is independent and computes coverage from public antenna data.
