Vivo (Bovespa: VIVO3 / VIVO4; NYSE：VIV)是南美洲與巴西境內最大的行動電話服務供應商，有超過3000萬名使用者。 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 will operates in both CDMA and GSM.
