Vodafone takes the fight to VoIP

Vodafone is responding aggressively to the rise of VoIP by launching a low cost, flat rate phone service of its own, using capacity on its 3G network. Echoing similar moves by its US joint venture Verizon Wireless, Vodafone’s plan reflects the main defense that cellcos have against the non-3G operators that seek to steal their voice markets using voice over Wi-Fi or, in future, WiMAX.
