Google’s RCS has 800M active users and it’s projected to hit 1B by the end of the year matching iMessage’s usage. Whether people actually know that it’s RCS or not, it’s been a pretty successful service for Google so far.

I use RCS with all of my Android user friends. It’s always been turned on by default for us.

Not sure what you mean not many Android users are using it?

Meanwhile, Google Voice doesn’t even have it enabled!
