Are there any (preferably FOSS) RCS/SMS/MMS apps as an alternative to Google Messages? I can't convince anyone to switch to signal and would like to at least use an app that I trust. Eventually I'll be moving to a privacy-respecting mobile OS so I'll need an SMS app to run without Google Play Services, but I don't want to totally miss out on RCS. Are there any alternatives? Is this even possible?
Google Messages (and I think Samsung Messages) is the only app that supports RCS.
Outside of Google, the RCS APIs are currently only available for pre installed System apps.
I'm interested in knowing too!
Google messages also has some annoying moments where the RCS will just quit working for no reason at all, first falling back from e2ee to standard RCS which is very annoying, and in some cases it will drop even further back to SMS if you haven't prevented it from doing so in the settings.
The messages app feels great to use, but it's privacy attempts aside from the e2ee are just not there IMO
