In Canada, the feds just demanded that the cell phone companies turn the information over to them. This story was reported in December of 2021. I believe the feds just extended the request through 2022. I imagine that the SIM card inside my phone gives them everything they need to spy on me, and my cell phone company gave me the SIM card when I signed up for a plan. I suppose a person could leave the phone at home if they didn’t want to be tracked.
You can buy a faraday bag, which cloaks your phone from all bluetooth, cell, Wi-Fi and GPS signal exchange.
However, I have to wonder if an old quote is not similarly apllicable to the topic of phones.
“When it comes time to bury your guns, it’s time dig them back up”
