A friend of mine went much further than I did, with an interesting result:
“I turned off all devices, turned off wifi, wrapped my cell in aluminum foil and stuck that and my laptop in the microwave, which is a Faraday cage of sorts. I heard nothing, but when I turned my phone back on, At&T sent a text that they discovered an issue with my wifi. Hopefully, I’m not on some list now. Since when are we REQUIRED to keep wifi plugged in?”
Geez, who’s on what list?
George Orwell comes to mind.
