Facebook quitely launches free voice calling over Wi-fi on Facebook Messenger iPhone app in United States.
Facebook had a big announcement this week with the Facebook Graph Search. The goodies keep on coming. Yesterday Facebook enabled free voice calling over Wi-fi on its iPhone Facebook Messenger App reports The Verge.
Facebook had tested that offer in Canada and now rolls it out in the United States. You now can talk for free with your Facebook friends on your iPhone over a Wi-fi connection. This only works for now on the iPhone Messenger app and not on Android.
It is of course just a matter of time Facebook is going to offer this on Android and also on the facebook.com site.
