This morning, AT&T announced that it has added Advanced Messaging and Video Calling to its Rich Communication Services (RCS) platform. The new additions join Voice-over-LTE (VoLTE), HD Voice, WiFi Calling, and NymberSync.
With Advanced Messaging, users can send larger files (up to 10MB), but will also know when messages are delivered, read, and when someone is typing a reply. It’s basically a more robust texting experience that you already get through other messaging platforms.
As for Video Calling, we are simply talking about placing HD Voice calls with video. Like with Verizon’s HD Voice and Video Calling, AT&T customers don’t need to download a new Video Calling app, you and the person you are calling just need to be using devices that support the feature through the native dialer, and be in an HD Voice calling area.
Both of these features are available today, assuming you have a compatible device. At this time, Advanced Messaging is only available on the Galaxy S5 Mini (hah!) and Galaxy S6 Active. Video Calling is only available on the S6 Active.
