What do you use to send and receive SMS on your computer? I've tried KDE Connect but found it too buggy to use daily.
There are multiple ways to bridge SMS to XMPP. Works nicely in my experience.
If you are US or Canada based this is also worth a look: https://jmp.chat/

What bugs are you encountering with KDE Connect?
Most of the time I can't even send a message with it - I'll type the message out, click send and… nothing. No indication of error, no indication of success. There's also an issue with loading the message history right after launch. A lot of times it doesn't work or only works partially. App on the phone has full permissions, set to unrestricted battery, etc.
I used Google Messages directly for a while, but then a Matrix bridge that uses Google Messages was released, so now I use that. If you want to try it, matrix-docker-ansible-deploy makes it really easy to self-host, but if you don't want to do that, something like Beeper can probably do it.
Can it handle MMS, pictures, etc?
