    Cell phone tower triangulation only gives a rough approximation of location

    That’s why I said they send that to allow the phone’s GPS to get a lock quicker and more accurate. All cell phone towers have GPS. Agps means the tower sends its GPS constellation to the phone so it doesn’t take 5 minutes to lock.

    So yes, even with GPS disabled, the phone company has a rough idea where you are.

    If you are in the city on high band 5g, that location is known within 15 to 600 meters.
