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.
Only thing I know about RCS is that it has caused a few of my texts to never be sent, because the "send as normal text if RCS doesn't work" also didn't work. Other than that it has done nothing for me.
Except the commenter above is talking about SMS/MMS which is not encrypted and very easy for a government to snoop on via the telecom company. You have no protections.
