T-Mobile has announced a new feature for Android phones on its network: T-Mobile Video Calling. Rather than just another video calling app, however, Video Calling will work right from your phone's dialer. All you'll need to do is choose between the video or voice call button when placing a call.
You can make T-Mobile Video Calls to and from capable devices on any available LTE connection − using data straight from your high-speed data bucket − as well as over Wi-Fi. Like HD Voice calls, T-Mobile Video Calling moves seamlessly between LTE and Wi-Fi. And, if you move off LTE or Wi-Fi to a slower connection, your video call seamlessly switches over to a voice call. If you move back to LTE or Wi-Fi, switch it back to video with a single tap.
Currently, Video Calling is supported on the Samsung Galaxy S6 edge+ and the Galaxy Note 5 after a software update. If you're using an S6 edge+ or Note 5, you can check your phone's Settings to download the update now. Updates for the Galaxy S6 and S6 edge will be available at some point next week, with updates for three more, as-yet-unnamed phones available by the end of the year.
