      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).
