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.
