You can place a free phone or video call to anyone who uses Messenger. Tap or click the person's name to open the chat.   You can video or voice chat with just one person or an entire group.  There is no fee to place calls with Messenger, but you will use your mobile data if you are not connected to a wireless network. A video chat can eat up data quickly, so try to limit video chats to when you're connected to Wi-Fi To make a voice call, tap the regular phone receiver icon at the top-right corner. For a video call, tap the video camera icon directly to its right. Messenger will attempt to place a call to the other party. Their device will ring, provided they have call notifications enabled and an active internet connection. If it's your first time using this feature, follow the on-screen instructions to give Messenger access to your camera and/or microphone. It'll appear on the screen while you're chatting. This disconnects you from the call and returns you to Messenger.
