Facebook adds VoIP calling to iOS service

Facebook adds VoIP calling to iOS serviceFacebook has updated its iOS app this week, adding free VoIP calling for users in the U.S. and Canada.

The social networking giant had been testing the feature through its Messenger iOS app since early January.

Accessing the free calling is simple enough. Tapping a friend’s name in the chat menu, and then heading to “info” will show off a new option to make a free call.

For the call to work, both users must have the latest version of Facebook.

The calls work via your existing data plan.
