No kidding and it seems like he went to PhD levels of complexity in this exercise.

Agree. The simpler solution, I keep coming back to, get a "Faraday bag" and keep your phone in it. Pull the phone out only when you need it. If you still want PhD levels of complexity then I suppose you can try to be very methodical about where/when you "unbag" your smart phone so as not to reveal too much information about your habits, locale.

  What's the faraday bag for? I mean, can't you just turn the phone off? Or even just put in on airplane mode?

    I have read (without citations) that those measures are not enough. Off is not "off", Airplane Mode is at the discretion of the OS, pulling the SIM still leaves other radios on the device available, etc.

      I've put an emf meter up to my phone in airplane mode and it doesn't emit anything at least.

        Oh I need to try this! I just developed a super sensitive giga broadband detector. I am sure it will pick up something, thanks for the reminder!

  There are several issues with the Faraday bag approach: - Your (mainstream, commercial, surveillance-capitalism-AI-feeding moloch) smartphone remains a massive privacy / surveillance / manipulation threat. - Odds are strong that you'll be leaving a strong location and travel signal by where and when you choose to unbag your device. Or bag it, if that occurs only near specific locations you intend to make private, effectively circling the area with a large, red "don't look here" sign. - Your contacts list, contact history, activity, and data remain on what is primarily a surveillance tool to be used against you. The approach taken here, in isolating the cellular network point-of-contact to a modem/router, which can reidentify itself (BSSID) and swap SIMs (this ... should be sufficient to break chain-of-event tracking, though you might find yourself burning through SIMs rather quickly), and relying on other, more-trusted devices for actual communications (voice, SMS (ugh!), Signal (much better), etc., is one I've been exploring for similar reasons. Suggested in a recent HN comment here: <https://news.ycombinator.com/item?id=45604692 https://news.ycombinator.com/item?id=45604692>. Yes, it's more than a slight PITA, but such is the experience of swimming upstream.
