The Verge broke today that Facebook has launched free voice calling to anyone on Facebook for iPhone users in the US. It was originally launched in Canada as testing purposes and it worked well to release it in the states. The feature will be access through the Facebook Messenger app for iOS by opening a chat with someone, press the “i” button then tap Free Call. You will be able to use this via Wi-Fi or your cellular data connection if your in a bad calling signal or don’t want to use your minutes. No word if the feature will be coming to Android but time will tell.
