Faraday cages can attenuate most radio signals, not just WiFi. If you still want “AM radio”, VHF (“FM radio”, OTA TV), and cellular, you would need an external antenna for each of these.
which i’d imagine barely anyone cares about any more, if you have wifi you don’t really need a phone signal and radio can be had via internet (same for TV)
