Facebook has launched a new app called Messenger Calls for Android, which allows users to make phone calls over the internet using their Facebook account. The app is available for free from the Google Play Store.

Messenger Calls works by using your phone's data connection or Wi-Fi to connect to Facebook's servers. Once connected, you can make calls to any other Facebook user who has the Messenger Calls app installed. Calls are free to make and receive, and there are no limits on the length of calls.

Messenger Calls also includes a number of features that make it easy to stay connected with your friends and family. You can see when your friends are online and available to talk, and you can send them messages or video chat with them. You can also create group calls with up to 50 people.
