Vivo (Bovespa: VIVO3 / VIVO4; NYSE: VIV) is the largest mobile phone service provider in Brazil and in South America with over 28 million users. It originated from the merger of several Brazilian mobile phone operations under a joint-venture owned equally by Portuguese Portugal Telecom and Spanish Telefónica. Most of its network is IS-95/cdmaOne based, although there are parts of it which are still analog AMPS and parts (resulting from acquisition of other companies) which are TDMA (IS-136) based. The network is being gradually converted to CDMA2000. In 2006, after years being the only CDMA network, Vivo announced a GSM network, and that it would operate in both CDMA and GSM[1]. The Vivo brand was launched on April 13 2003. Until 2006, the group was composed of six holding companies which, as announced in November 2005, merged into a single holding company, Vivo Participações S.A.. The operation was concluded on February 22 2006. Merged companiesThe following operators merged to form Vivo: Portugal Telecom-owned
