Re: You Can Phone Me Or SMS me; Period
Quite simply, the lack of interoperability between services means that sometimes the only guaranteed way to reach a person is via old-fashioned text.
Chat/RCS doesn't actually change this service guarantee; where either user/network doesn't have RCS/Chat the default is to drop into SMS. Given the installed base of mobile phones, the majority will only have SMS capabilities and will do so for some years yet.
I'm a little surprised that RCS/Chat isn't a mandatory service for 5G and thus 5G client devices have to support it - gets around the Apple iMessage issue...
