If that's true, maybe you can explain how (as I said above) this metal case blocked transmissions for my older phone (while inside the case, with audible ring), yet was able to receive signal from a newer phone. The newer phone obviously had to be more powerful/capable in some way. The case was designed with a metal-embedded o-ring between two enclosing metal shell halves.
Assuming that it not some totally fake product. A Faraday bag will, as per the laws of physics, completely block any and all radio signals, or, indeed, electromagnetic radiation of any kind.
