Facebook recently promised that their newest update to Facebook Messenger for the iPhone would include VoIP, which would let you call your Friends using a cellular or wi-fi data connection instead of your phone’s plan minutes.

Gizmodo recently tested the new feature and found it worked perfectly on their office wi-fi. To use it, just click on a Friend’s profile in FB Messenger, then click on “Free Call”.

Just remember to make your calls while you’re on wi-fi otherwise your standard data usage rates will apply.

You can download Facebook Messenger here.
