Cell tracking is external to the phone. It’s done by the towers - they know signal strength, and by using known tables of that data, cell providers know pretty accurately where your phone is.
To block this you’d need a device that lacks any cellular technology whatsoever. Wifi only.
And that has the same issues, especially with companies like Comcast/Xfiniti using their cable modems to track all the devices around them, even if you don’t connect to them.
Many of us have been saying the ADL is shit for decades now.
