You can use KDE Connect[1] for send SMS from a Win / Mac or Linux machine. This also works with Android.
This is fantastic. Thank you so much!!

There is KDE Connect. You can easily respond to texts from that.
Barring that, sending a text is a simple one-liner in the terminal. Worst case, you can just run the command via ssh or whatever other workflow you may want.
Biggest question: Can I send SMS, on this phone, from another computer?
The biggest reason I ditched my iPhone for Android was the excellent implementation of in-browser messaging, to and from my phone, on any computer with a web browser.
I don't need to be able to text from "any computer with a web browser", but if I could send SMS from Win / Mac / Linux machines that I owned, that would be a huge incentive for me to give this platform a shot.
