1. True RCS isn't supposed to go through internet, it's supposed to go through same way as SMS and voice calls (which is also a data connection, but specific to sms/rcs/voice)
2. That's not a requirement even though Google does their best to kill all alternative implementations. (Samsung had one, but Google paid them a lot of money to get rid of it. I have to admit I don't know who is left with their own RCS client)
> So, RCS is not a replacement for SMS.
It's 100% a replacement to SMS, it's literally defined in the same spec as SMS over LTE, as an upgrade to SMS. Though yeah Google made it, this... uh... thing. RCS is technically a federated standard, but Google killed every part of the federation and some parts of the standard.
RCS might be a federated standard, but before Google not even Verizon at AT&T wanted to federate.
Not sure why you'd say "not even Verizon". Verizon is literally the worst carrier worldwide (ok maybe after NTT) with regards to interoperability.
I think they're saying that the two biggest US carriers didn't want to interoperate.
Which is insane. An SMS replacement where Verizon and AT&T users cannot message each other is insane.
