By locking your SIM card, you ensure that no one except yourself can use your device while your SIM card is in place (assuming you are the only person who knows the SIM PIN). Note that your SIM card may be installed with a default PIN (ask your wireless operator's Customer Care department if you don't know the default SIM PIN).

To lock your SIM card, do the following:

1. From the Jump screen, press MENU then select Settings > SIM Center to open the SIM Center screen.
2. Scroll down to the SIM Card Lock group box.
   
3. Highlight and press the Enable SIM Card Lock button. The Enable SIM Card Lock dialog box appears.
   
4. Type your PIN and select Enable . You'll receive a confirmation dialog box that your SIM card is locked. Now, you will be prompted to type your SIM PIN whenever you unlock key guard.
