Buy a broadcom smartphone. Turn bluetooth off, and set it to airplane mode. Then Bluepwn your device, with bluetooth turned off.

Funny how airplane mode didn't work.

That's just one of the quirks. Baseband and what qualcomm is tracking is way worse.

I recommend buying an old Motorola Calypso device and fiddling with osmocomBB, you can DIY an IMSI catcher pretty easily. And you'll be mind blown how many class0 SMS you'll receive per day, just for tracking you. Back in the days you could track people's phones remotely but the popularity of HushSMS and other tools made cell providers block class0 SMS not sent by themselves.

This wiki article is a nice overview: https://github.com/CellularPrivacy/Android-IMSI-Catcher-Dete...

Saying more words and then linking to a page from an IMSI catcher's wiki (where it doesn't talk about radio on/off states) isn't exactly "providing sources".

You made the assertion that basebands remain in contact with towers even in airplane mode, and so can be tracked. Someone asked for supporting evidence for that claim. You've responded with examples and links to different issues. It's a fairly extraordinary claim (it's not one I'd heard before - it's clear that other radios may remain alive for various purposes even when airplane mode is switched on, given that you can use wifi and bluetooth on planes, but you're the first person I've heard make this claim about the cellular radio), and you haven't provided any evidence to back it up at all.
