Eircell
Eircell commenced operation in 1986 as the Mobile and Broadcast division of Telecom Éireann. The GSM network went live on July 1993. Eircell handled the Irish mobile phone networks defined by the access codes 088 (analogue TACS system) and 087 (digital GSM 900 system) from 1984 until its transfer to Vodafone in 2001. Usage of the service remained low until it became a separate subsidiary, Eircell Limited, in 1997. In October 1997, Eircell introduced the analogue prepaid pay as you go system under the Ready To Go brand, and turned mobile communications in Ireland into a mass-market product. From early 1997 Eircell faced competition from Esat Digifone, then a joint venture between Denis O'Brien's Esat Telecom Group plc and Telenor of Norway. In 2000, Vodafone made an offer for the company to Eircell's parent, eircom Plc., which saw the company demerge from Eircom plc into a separate plc, Eircell 2000 plc (trading name: Eircell Vodafone), which was then acquired by Vodafone. In 2002, Eircell Vodafone was rebranded as Vodafone Ireland plc.
In 2001, Eircell closed down its original analogue TACS (088) system, and Vodafone Ireland now operates a purely digital (GSM/UMTS) network.
