try it ..meant...
see if you have the signal.
YOU can’t do it unless you are some kind of hacker,
Fridge may make a sound barrier but it does not keep SPIES from accessing your phone for whatever purpose to be utilized then or later after you pull it out of the Fridge.
that was the whole point of the discussion..does a Fridge make a Faraday cage.
Mostly NO
You told me to try it and I did. The phones didn’t wake up. But that is beside the real point. If there’s a sound barrier between the phone and the conversation a faraday cage is meaningless.
People are way overthinking this. If you always assume a cell phone is a spy it’s easy to defeat. In fact if it’s a spy you can use it to deliberately spread mis-information, to your advantage.
Put the phone under a couch cushion, go to the next room, it’s no going to pick up anything even if it’s on. Easy.
