Thanks for the info! I guess that’s ultimately what I’m looking for more about: how much do we know about cellular traffic? Obviously with encryption we can’t just directly read cell signals to find out what’s being sent, so do people just record the volume of data being sent in individual packets and make educated guesses?

It seems plausible to run a simple(non-AI) algorithm to isolate probable conversations and send stripped and compressed audio chunks along with normal data. I assume that’s still probably too hard to hide, but if anyone out there knows of someone that’s looked for this stuff, I’d love to check it out.
