Agreed. We can only mitigate by tactics: -not associating the device ID's to personal ID's. -only using cellular in limited situations. -rotating the SIMs periodically with other family members
You don’t get to choose those things if you don’t choose what the radio does. Swapping SIMs around doesn’t accomplish that. The hardware and software that the baseband has entirely within the confines of its own black box is enough to track you.
