RCS It's still getting rolled out a lot of places. Google sees it as the successor to SMS and it's built into native messaging apps. I recently saw cross-carrier support get enabled locally and that made it universal enough that so far anyone I message that's running Android is already connected via RCS. Apple intentionally doesn't support RCS in order to keep imessages from interoperating with android.
