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.
I think they found imessage not to be a leading platform so AFAIK this isn’t the case for now. Maybe if more people start using it they’ll revisit the question.
