eir telecommunications service

eir is the trading name for Eircom Limited, the largest telecommunications operator in Ireland. The brand has a long history, originating from the state-owned Department of Posts and Telegraphs, which later became Telecom Éireann before being privatized as Eircom and eventually rebranding to 'eir' in 2015.

Today, the company provides a comprehensive suite of digital services including mobile networking, fixed-line broadband, and television services across the Republic of Ireland. As a service provider, its 'manufacturing' or operational footprint is centered within the Irish market through its extensive fiber network and cellular infrastructure.

Since 2018, the brand has been under the ownership of a consortium led by NJJ Telecom Europe, the investment vehicle of French telecoms entrepreneur Xavier Niel. This ownership transition marked a significant shift toward modernizing the brand's infrastructure to meet 5G and high-speed fiber demands in the region.
