These bags stop radio waves, so your phone disappears off the global grid. Even when you turn off your phone it usually is not all the way off, and continues to contact the network from time to time. In the past one could take out the battery, but modern phones do not offer that freedom. If you would like for your phone to be quiet, and not to be tracked these are the containers for it. Some people think it is a good idea to be off the grid from time to time just so there is not an expectation that you are always available. Some folks are worried about spyware that continues to contact the network even when you think you turned off the phone. Some journalists and politically active folks worry about this. In any event, these bags are "Faraday cages" and trap electromagnetic energy. Obviously you cannot receive or make calls when the phones are inside. Nor can you get texts nor have it search for WiFi. Low cost and effective, and much better than aluminum foil. (I do not know if aluminum foil hats stop brain waves, but that is another topic. ;-)
