It was created when the Vodafone Group bought Eircell the mobile arm of Telecom Éireann.

A 4G network was launched in October 2013 Vodafone claim over 90% of the island of Ireland is covered by their 4G network within the Republic. Vodafone 4G operates on the 800/1800 network offering speeds of up to 75Mbit/s. They are also currently building a new kind of 4G called 4G+ this enables speeds of 225Mbit/s on devices that support this and the initial roll out of this service will be in major towns and cities first becoming more widespread over time. Vodafone 4G is available to over 6 cities and 500 towns in the Republic of Ireland making Vodafone the strongest and most widespread 4G service offered in Ireland. Vodafone Ireland also launched a HD voice service between customers on the Vodafone network only this makes calls crystal clear and cuts out background noise to make calls more enjoyable and easier to hear for customers you must have 3G signal for HD voice to work and also must be between Vodafone customers only calling to other networks does not work for HD voice.

The company also offers a range of fixed-line services including traditional telephone services, ADSL2+ and fibre (FTTC) high speed broadband using the Vodafone@Home brand. These services are delivered using the eircom wholesale access network with Vodafone's own back-haul capacity. In some areas, Vodafone has made use of Local-Loop Unbundling (LLU) and has its own equipment in the local exchange operated in partnership with BT Ireland Numbers issued by Vodafone Ireland usually start with 087 (+353 87), however full number portability is in use in Ireland so the mobile prefix is not a reliable indicator of which network the number is hosted on. ==Eircell== (詳細は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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vodafone Ireland」の詳細全文を読む スポンサード リンク
