Samsung has released a new video in support of Google’s #GetTheMessage campaign which calls for Apple to adopt RCS or “Rich Communication Services,” the cross-platform protocol pitched as a successor to SMS that adopts many of the features found in modern messaging apps… like Apple’s own iMessage.
Signal is the way to go. No need to expose metadata to your mobile carrier via RCS. Also, currently you need Google’s proprietary garbage message app to make use of RCS. There’s litterally no reason to do this.
