Get a small metal tin with a removable lid, like a small cosmetic tin, candy tin, etc, that you can place your cellphone inside. The lid should be removable but have overlapping edges at least 1/4" long. Use a rotary tool like a dremel or sandpaper to remove all the paint and plastic coating off of the edges of the lid and tin that overlap when the lid is on. The goal is to ensure metal-to-metal contact on the entire perimeter of the lid-to-tin joint. If you can do this you have created a Faraday cage that will stop all radio frequency communications to your cell phone. Test it by leaving your cellphone on, place it in the tin and seal the lid. Make sure you are in a location where you have 5-bars or perfect signal strength. Have someone send the cellphone a text message. Remove the cellphone from the tin and check if the message was received. If not, you now have a "safe" cellphone On/Off switch. Most cellphones are never "really" off when you turn them off. Pass this on to anyone who may need an effective On/Off switch.
