1. What is GPS

   • Stands for: Global Positioning System
   • satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense
   • How it works
     • GPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. GPS receivers take this information and use triangulation to calculate the user's exact location.

2. Prevent your mobile phone from being stolen

   • Keep details.
     • Make a record of all your phone information and keep this in a safe place. Include the following elements in the information
   • Add a security mark
     • Use an ultra violet pen to print your post code and house number onto both your mobile handset and battery. This makes it easily identifiable as your property if lost or stolen
   • use a security code/Password
     • This will make it less valuable to a thief and deny them access to personal numbers stored on your SIM card.
   • Register with a network operator
     • If your phone is stolen, report the loss to them immediately. Using your IMEI number, they may be able to block your hand set and account details.
   • Have your number disabled
     • In addition to reporting your phone lost or stolen, you should also disable your phone number (not account) so that no further charges can be applied.
   • Investigation
     • Sometimes this can prevent (or at least delay) the carrier from launching a collections effort and tainting your credit, if things get ugly.
   • Change Display
     • This will make your phone look like an old monochrome one. A very experienced hobbyist can also replace all white SMD LEDs in the phone with lime-green ones (better not only in display, but also in keyboard).
   • Install anti theft software
     • There are suppliers that provide modern anti theft software for your phone. The software enables you to remotely contact your mobile and stay in control.
