What is RCS? RCS stands for Rich Communication Services which is a communication protocol similar to SMS messages but with a text message system that is more rich.

RCS is essentially enhanced SMS and MMS. To get it, you need your carrier to support it, your device to support it, and a compatible app. It works with text, images, and video, and you can use it to send both individual or group text messages.
