how can one hide the location of a mobile phone in order to avoid being tracked or surveillanced?
Wrap it in several layers of lead foil.Eat the sim card.Dip it in concentrated hexaflouric acid.Travel out of town - large rural cells reduce the chance of finding you.Kill yourself, and stipulate in your will that the phone be buried with you.Move into a nuclear bunker.Encase your entire home in copper mesh, forming a habitable Faraday cage.Or, maybe, you just try switching it off...
That phrase "habitable Faraday cage" makes me think: Faraday would be a really good name for a hamster, or a rat, or even a parakeet, just as long as that animal is normally kept in a metal cage. ... I dunno. Is that a joke that works, or is it too erudite? Probably no worse than a dog named Pavlov, or a cat named Schrodinger. Maybe this comment belongs in the Pets forum. Sorry for straying off topic. ;-)
Some phones you still have to take the battery out... but you had some good ideas! ;)
I would suggest purchasing one of the "disposable pay as you go phones".They're very popular for terrorists who don't want their locations to be discovered.
take the battery out.
