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.
Most carriers support it. When they don’t, the protocol can use a bridge. Google hosts a bridge. I guess you could also use the bridge if the carrier is trying to charge for it.
