With the widespread growth of GPS technologies, many cell phones now come directly linked to satellite tracking systems. Even if your cell phone is not GPS-enabled, cell phone companies can triangulate your position based on the cell phone towers that process your call. However, you can block most cell phone tracking with minimal effort.
Disable your cell phone's location-tracking capabilities by changing your privacy settings from “location-on” to “E991” or “911-only.” “E991” allows others to track your phone only when you make an emergency call.
Delete any smart phone applications that track your location. Many smart phone applications use your phone's GPS capabilities to determine your location, and some will store your location history and may be required to provide it to law enforcement if asked.
Remove your phone's battery or leave the phone at home if you want to be certain that no one can track you on a particular trip.
