      Faraday bags work… But test them.

      I got a cheapo $7 Chromebook sized bag that seemed to work for my SOs iphone. We don’t use NFC so I couldn’t test that.

      No BT, WiFi, or Cell, and probably no GPS.

      I only did casual testing.

      The screen still showed the signal having low bars for WiFi and cellular, but it didn’t actually receive a signal at all when trying to call or use the net, not even with the top of the bag open a sliver and my hand in there.

      If the device was off or in airplane mode and in the bag, I’d be comfortable assuming it was safely hidden from tracking.

      I haven’t thoroughly tested my various personal devices, but I expect identical results.

      I think everyone should probably have a bag like this around, in a go-bag or something, just in case. And it’s safer to have your phone available than not, as long as it’s secure (use a pin or password to lock it, use encryption, put emergency info on it for first responders).

        If you’re going to use a Faraday bag, use it regularly, like every day at random times.

        Imagine you are being accused of a crime. The crime occured at 8pm. The phone records show that your phone went dark at your house 7pm and then reconnected at 9pm at your house. The crime scene is 1 hour away from your home by foot. Records show this is the only time your phone went dark in a very long time.

        So if you bag your phone (aluminium foil bags work pretty good too), do it regularly, randomly, and don’t bag it and unbag it immediately before leaving or after getting home
