Vivo (BM&F Bovespa:VIVO3 / VIVO4) is the largest mobile phone service provider in Brazil and in South America with over 40 million users[1]. 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 the major cities, where the Company plans to provide Mobile Internet Access.
In 2006, after years being the only CDMA network, Vivo announced a GSM network, and that it would operate in both CDMA and GSM[2].
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.
Vivo also operate a 3G Network, EVDO and UMTS.
