According to comments of David Katz, Yahoo’s VP of Mobile, Yahoo will soon be offering versions of Yahoo Messenger that will support video calling.
The Yahoo Messenger app will be free and allow Android and iPhone users to conduct video chats. It would support video calls between devices and desktop computers. Unlike Apple’s FaceTime, the app will work not only over a WiFi connection, but also over a carrier’s standard wireless network.
Yahoo already has a Messenger app available on Android, but it currently supports only instant messaging. An update to the app would include support for video calls.
As for iPhone users, Skype does not offer a video calling capability on its iPhone app. While applications like Tango and Fring do support video calls through Wi-Fi and 3G connectivity but Yahoo has a larger user base than them.
According to Yahoo, Messenger’s user base consists of 81 million users worldwide.
