Earlier Facebook Messenger for iPhone got free voice calling feature in US & Canada and later it is rolled out for Android users in Canada. Now, today without any buzz Facebook silently rolled out the voice-calling functionality for users in India too. The voice calling feature of Facebook Messenger allows users to call their Facebook friends for free over 3G or on Wi-Fi networks.
This functionality is not available for Facebook Messenger for windows Phone yet. Although the conference call facility is not available but you can rate the call quality as soon as you finish the call. Have you tried the new calling feature on Facebook Messenger yet or not?
