T-Mobile just introduced this new feature by Michal Addady @FortuneMagazine September 3, 2015, 5:45 PM EDT E-mail Tweet Facebook Linkedin Share icons T-Mobile announced the launch of its new T-Mobile Video Calling on Thursday. Neville Ray, the company’s chief technology officer, is calling it “a huge step forward in how Americans make mobile phone calls.” Ray stresses that this is not just another app. It’s built into your phone’s dialer, so there’s no need to download or register for anything extra. It’s very simple to use. You just have to choose between the voice call or video call options before making a call the way you normally would. Camera icons will be added to your contact list, appearing next to each number. If video calls aren’t available for a specific contact, the icon will be greyed out. T-Mobile is currently working with other services to ensure that video calls will be available across all wireless networks. A big problem with video call apps is that if you’re moving between wireless connections, your call could be disrupted. T-Mobile has fixed that problem. Your video call will switch from LTE to Wi-Fi as you move around. If you move from either LTE or Wi-Fi to a slower connection, it’ll just turn into a regular phone call; once you move back, simply press a button to return it to video. T-Mobile Video Calling is now available on the Samsung Galaxy S6 edge+ and the Samsung Galaxy Note 5 with the new software update. It will be available on the Galaxy S6 and S6 edge when the updates for those devices roll out next week.
