eircom is the principal provider of fixed-line telecommunications services in Ireland with approximately 2.2 million fixed-line telephone access channels in service.
Eircom Limited, trading as Eir (/ɛər/ AIR; stylised eir), is a large fixed, mobile and broadband telecommunications company in Ireland. The now privatised company, which is currently incorporated in Jersey, traces its origins to the Ireland's former state-owned monopoly telecommunication provider Telecom Éireann and its predecessors, P&T (the Dept. of Posts and Telegraphs) and before the foundation of the state, the telecommunications division of the GPO. It remains the largest telecommunications operator in Ireland and has overseas operations focused on the business and corporate telecom markets in the United Kingdom. The company was in majority state ownership until 1999, when it was privatised through a floatation on the Irish and New York Stock Exchanges.
Eir is currently majority owned by Xavier Niel's Iliad SA and his Paris-based NJJ Telecom Europe investment fund. The group includes French telecommunications provider Free and Iliad Italia.[4]
Eir operates a wholesale fixed-line network through its Open Eir unit, providing copper and fibre based access products to a wide range of Irish telecommunications companies. Its services include next generation access products, such as FTTH, FTTC (VDSL) and legacy copper based services, including ADSL and classic digital circuit switched products like PSTN and ISDN. It also offers a range of legacy leased line services.
The company's retail division markets these services directly to homes and businesses, and includes value added services like Eir TV and voice over broadband for home users and a wide range of digital services tailored to business customers.
Eir operates a national mobile network both under its own Eir brand and GoMo, a value-focused, online-only sub-brand. The network provides 2G, 3G, 4G and 5G services and ancillary services such as WiFi Calling and VoLTE.
