The #RCS protocol https://en.wikipedia.org/wiki/Rich_Communication_Services is available (enabled?) on most #Android phones.
I see several problems (vs SMS) and would like informed people to correct me if needed
1. it needs data access to communicate, vs SMS which only needs mobile phone access
2. all messages pass by #Google servers
3. rooted android phones (like mine with @GrapheneOS ) can't use it (I don't want!)
Please continue using SMS and Signal!
Retoot and answers appreciated
