Is there any FOSS alternative messenger that handles SMS and RCS? Supposedly RCS is an open standard, but I am not aware of any FOSS messenger that has it. I’d like to move away from google messenger, but there doesn’t look like there is an option just yet.
This is the closest I’ve been able to find - JMP which is used in Cheogram, a FOSS XMPP app, was working on it in May but I messaged them about it recently and there hasn’t been much development on it unfortunately. https://blog.jmp.chat/b/may-newsletter-2024
They allow you to have VOIP numbers and even a data only SIM with no KYC and pay in crypto if you want so it’s a pretty cool project overall. Maybe if more people message them about RCS it will become a higher priority.
