SCOTTSDALE, Ariz., March 4, 2010 - Market research firm, In-Stat  estimates the total number of mobile VoIP users will be reach 288 million by the end of 2013.  Of these, well over half will be associated with online mobile VoIP providers, under one-third will utilize mobile VoIP with 3G MVNOs or mobile operators, and 11% with WiMAX/LTE operators.   On a geographic basis, mobile VoIP will be heavily biased towards the Asia Pacific region, particularly among the online mobile VoIP services.

“The near-term opportunity for mobile VoIP is closely linked with the growing success of dual-mode phones and other Wi-Fi connected devices,” says Frank Dickson, In-Stat analyst. “However, mobile VoIP still poses a direct threat to operator voice revenue and operators are navigating how to balance new opportunity with the threat.”
