So many telecom operators claim that their users will get network coverage even inside an elevator. But according to Gauss' theorem, no charge is supposed to exist inside a closed conductor and an elevator (made of metal) is a closed conductor... So how is one supposed to get network coverage inside?

You're thinking in terms of electrostatics. Cell phones work using electrodynamics to transmit signals, i.e. photons/electromagnetic waves.

The elevator will attenuate some of the signal but at the right frequencies the signal will mostly pass through the elevator boundary.
