Cell phones inside shelters.The same Faraday Cage Effect also attenuates radio signals somewhat, including cell phones.  But if you ordinarily have a relatively strong signal at your home, you should still get reception when inside the shelter.  Digital signals tend to do pretty well with variable signal strength so the reception would need to be pretty weak already to vanish completely inside the safe room.
