Group Video Chat in Messenger is an easy-to-use means to stay connected face-to-face with your friends and family. Starting today, Group Video Chat is rolling out worldwide to Android and iOS devices.

This new feature is easy to use, free over Wifi and you can see up to six people at a time. Not to worry, however, if your group is a little larger because up to 50 people can listen and chime in via voice and stay involved in the chat by sending text, stickers, emojis and GIFs.
