I was looking at cell phones, tracking, geolocation, and SIM cards and the bottom line is this:
- Your location is triangulated every 10 seconds to access the closest cell tower, making it easy for emergency services to find you (for example).
- Removing the SIM card will not change the ability for your phone to be traced, since the trace is based on the connection to the cell tower.
So I think that if you took the SIM card out, but did not change your location significantly, that 10 second trace would continue to "identify" your cell phone.
Not sure what would happen if you took the SIM card out, traveled a significant distance without it, and put a new one in if that would change things.
Perhaps not, as you would still be bouncing off the cell towers as you moved along.
Although if you passed through or even stopped in a place where you know there was no cell phone reception at all, that might be helpful (or harmful), depending on your perspective.
I do not seek; I find.
