    Aluminum foil works. At least, I can’t receive calls or texts through it last I tried.

    Get the heavy duty kind. It’s not any more conductive, but is more durable against tearing.

    Note that a gap in your phone’s tracking data can look suspicious at times. Sometimes it’s less suspicious to leave your phone at home.

      Just want to note here that suspicion does not equal proof. Consider honestly what you are trying to accomplish, and what the risks are. There are absolutely scenarios in which even raising suspicion is unacceptable, and others where it isn’t.

        I’m not selling dope, I just don’t need Google knowing everywhere I went on the way to the doctor’s office, where I’ll probably sit and look at cat videos in the waiting room. I have anxiety and I can’t stand surveillance like this constantly.

      I second this. I’ve seen videos of cell phone thieves getting caught and they all have rolls of aluminum foil on them. I trust they know how to effectively block wireless signals.

      It’s not any more conductive

      quick note: you’re likely correct the conductivity may not be higher, but the conductance likely is.

      in other words, i second your suggestion of heavier duty foil (for EM reasons, skin effect etc) alongside the mechanical factors you mentioned.
