ELI5:If a closed metal elevator or car acts like a Faraday cage, how does my phone still get mobile signal inside?
I thought a Faraday cage blocks radio waves from getting in or out.
​
A closed metal elevator or a car seems like it should work like a Faraday cage, yet my phone often still shows signal and can make calls or use data.
​
Is a car or elevator not a "real" Faraday cage?
