Reminds me a a city in the PNW using outdoor APs to track people. Doesn’t matter if you’re on the free WiFi they still get your movement.

[FollowingTheDao]

Yes. Carry a cell sized Faraday bag.

You don't trust your own phone's airplane mode to shut the cell modem off?

[michaelmrose]

It doesn't. The baseband is still active and still responds to towers to a degree.

[HeatrayEnjoyer]

Would the FCC and FAA permit that?

[michaelmrose]

I don't understand the question. We are talking about the way it in fact works. I'm guessing that nobody at the FAA or FCC has any misunderstanding regarding this fact.

Also phones don't meaningfully actually interfere with modern avionics. If your safety on the flight actually depended on hundreds of people clicking a button consistently every time the majority of planes wouldn't make it.

[scinadier]

You do?

[FollowingTheDao]

Yes. At certain times.

[advisedwang]

Kinda defeats the point of having a cell phone tho

[FollowingTheDao]

Not for me. But I grew up without them so…

[advisedwang]

What are you doing with a cell phone that doesn't require it to be connected to cellular service?

[WhyNotHugo]

Mapping, navigation, listening to music, playing videogames, music instrument tuner. There are plenty of usages which don't require Internet/Cellular.

I often walk out of home with an old iPhone which doesn't have a SIM card and it does everything that I need it to.

The only thing that doesn't work is browsing the Internet or Messaging.

[morkalork]

Many cities have scanners that track cellphones via Bluetooth for monitoring traffic congestion.
