The other week, we announced that Facebook was rolling out a few new features to their Messaging app, along with testing a VoIP calling feature to Canada users. Today, The Verge is reporting that this feature is rolling out to US iPhone users now. There’s no update to the app needed. Within the Messenger app, you can go into a conversation with someone, click on the “i” button in the top-right corner and click on Free Call.
This is a huge feature that makes Facebook compete with apps like Skype (who Facebook has actually had a partnership with since 2011), Viber, Vonage, etc. Right now, only voice calling is available, so there’s no video chat. You can also use this service over WiFi or your cell network (watch that data usage though).
