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 Portugal Telecom and Spain's Telefónica.
Most of its network was initially IS-95/cdmaOne based, although there were parts of it that were still analog AMPS and parts (resulting from acquisition of other companies) using TDMA (IS-136). These are all being converted to GSM since 2006, when, after years being the only CDMA network, Vivo announced a GSM network, and that it would operate in both CDMA and GSM[2]. The CDMA network is being gradually converted to CDMA2000 in the major cities, where the company now provides mobile Internet access.
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 operates an EVDO and UMTS 3G network.
