Vodafone Ireland Limited, part of the Vodafone Group, is currently the largest mobile phone company in Ireland in terms of active subscribers, and was previously called Eircell. The mobile phone system in use is a digital GSM 900 system, and also a third-generation UMTS system (the first such 3G system in the Republic of Ireland; see communications in Ireland). The company offers email in addition to mobile phone products and services. The company's "pay as you go" mobile phone product is called Ready to Go, previously advertised by Republica's song of the same name. Vodafone commands a market share of 48% with 2,187,000 Subscribers in Ireland.
087 is the usual area code for mobile phone numbers serviced by Vodafone. However, following introduction of full number portability by the Commission for Communications Regulation, some subscribers may have 083, 085 or 086 prefixes instead.
The company also sponsored the Irish version of the Who Wants to Be a Millionaire? quiz show while it ran on RTÉ television.
