edward snowden himself demonstrated a phone case about 13 years ago that showed that even in airplane mode and even when turned off most phones emit radio signals

welcome to 13 years ago, it's way way way worse now

but you have verified gaussmeter evidence that it is true?

I don't think you'd use a gaussmeter but rather a mobile base station so you can measure the incoming pings

This was the approach used by SRLabs when testing their Blue Merle software for IMEI switching

doesn't necessarily have to be mobile radio protocol, just something that someone can pick up, doesn't have to be strong, about 20 metres is probably enough, and that won't detect it
