You can also get a faraday bag. They're available quite cheaply (I got my first one from infowars, 2 came in the package: 1 for my computer and a smaller one for a fairly large cell phone). I got another set from a company called Offgrid. They're better quality, you can do some research online with regards to that. The faraday bag is designed to keep what's inside safe from 'signals'. Again, not an expert so just look it up. I use one for my laptop and USB drives, CD's, DVD's, anything I want to keep safe in case of an electromagnetic pulse. They're good to prevent electronic theft of your credit cards or other ID cards with whatever the electronic info is coded onto them. I got 3 sizes from Offgrid, 1 for laptop, 1 for tablet, 1 for cell phone. I put my wallet in the tablet size as it fits nicely in my purse. They also come in a key fob size which my local 'automotive/hardware' store carries (Canadian Tire). If you keep your key fob in the bag, a thief can't steel the signal so reduces likely hood of car theft. Of course, you have to remove the phone or key fob from the bag in order to use it but the point is, it's not constantly exposed, you are in control. You're 'visible' for the time you've removed it from the bag and using your device. If you want to test how good the protection is, put your cell phone in the bag when it's turned on, then call yourself from another phone. It should not ring. When I did this, I called my cell from my landline and it went straight to voicemail. Interesting point: your microwave oven is a faraday bag. You can test whether or not it's leaking radiation by doing the same cell phone test. Put the phone in the microwave (it must be off), then call yourself. It shouldn't ring. If it does, it's leaky. I first heard of these things then did some internet research. You also don't need an old style phone, just get a no data plan for your current phone. Then you can still take photos. Do some research on this last point, I think its correct but double check.
