Three is one of Ireland’s leading mobile operators with 35% market share and almost 2.4 million customers (as of December 2020).

Our network is built for data; with 99% 4G coverage, and we carry over 60% of all mobile data on our network, that’s more than all other operators combined. Three has recently launched its 5G network which is available to customers in every county.

Three has over 1400 employees throughout Ireland, with our head office in Dublin, our award-winning contact centre in Limerick where our 450-strong team manages 1.4 million calls every year, and 61 retail stores nationwide.

Three has to date invested close to €2 billion in building our business in Ireland. This includes a €700 million investment in upgrading and expanding our network and in Three’s digital transformation, which will deliver a cutting-edge experience for both our customers and our employees.

Annually, Three continues to invest over €100 million into our business to ensure we continue to deliver the best network, experience and service for our customers.
