There were a lot of rumors going around about Facebook coming out with their own phone, but according to the Washington Post, Mark Zuckerberg and those close to him regarding business ventures have decided to do it with software instead of hardware.

Here's how it works. If you download the Facebook Messenger app, make sure the people you talk to the most have it too. When you connect to it and choose one of your Facebook contacts and hit the little "i" icon, you'll see a "free call" option pop up.

Oh, and make sure you're on your WiFi setting as well, even though you can use it with just your cellular network because it'll eat up a lot of data.
