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.
Phone number resolution is already a feature with identity servers but most servers don’t implement it.
Also have to choose a server increases the barrier of entry. I guess element works around that by defaulting to matrix.org although that’s not a great solution.
