You don't need a very old car, just one that is old enough the cellular network doesn't work any more.
Some vehicles were made for 3g, and can't go to 4g for example.
Just put a faraday cage around the antenna.
My VW has carplay / android auto but the built-in Sim no longer functions (2g).
From 2011 has most modern luxuries
2g antenna sare still up and running. Every new generation is add on top of the previous like a new layer of the network. And telemetry can be collected through older gen network.
TMobile recently dropped 3g I think. I have an old iphone (4 I think) and they could not get my sim to work on it because it did not support 4g.
Not everywhere in the world. Australia have turned off 2g for instance.
TIL. But why would you do that ? Ain't it more convenient to keep every gen ?
We're a bit mad out here, we turned off CDMA in favour of 3G. The 3G system our main telco implemented was built for England and didn't have amps built into the specifications.
Every site that was rolled out in regional areas needed to be attended to and upgraded with amplifiers (I know as I was one of such techs) doing heaps more work during the changeover period.
I believe the main reason is to reduce the volume of channels being broadcast on, to free up for other services (our analogue TV is turned off too).
