TESTING NOTE: Please do not use music playback to test the Faraday Box. If the music was already loaded or buffered before the phone was placed inside the box, it may continue playing even after the signal is blocked. Because of this, music playback is not a reliable way to test signal blocking. For a more accurate test, we kindly recommend one of the following methods:
Phone call test
Place your phone fully inside the Faraday Box and close the lid completely. Then use another phone to call it. If the box is working properly, the call should not go through.
Car key fob test
Place your car remote key fob inside the Faraday Box and close the lid completely. Then try unlocking or starting the vehicle. If the box is working properly, the car should not detect the key signal.
Our Faraday Box is designed to effectively block wireless signals, and both of the above methods are much more reliable ways to test the shielding performance.
