"You can in fact dump a phone into a fridge or freezer, which (at least here) have steel sheets all over them. Phones still get cellular service."
Not necessarily true. I used a fridge as a quick alternative to Faraday cage for device testing and it worked fine. It was an old, heavy fridge though, newer ones may contain more plastics and fail to shield properly.
