Facebook’s steady updates on both iOS and Android devices, is no time coming to an end. Facebook is bringing free VoIP to its Android Messenger app in the US. Your app will not require any manual update, you will know if this feature is enabled on your phone by clicking the “i” icon top right corner, next to your friends name in the messenger app, and select free call. Just Tried it out on my T-Mobile Samsung Galaxy SII and Nexus 4, it works pretty good and clear too. Let us know what you about the update in the comment section.
