Enabling/Disabling the PIN Security Feature
When the PIN security feature is enabled, you are prompted to enter your PIN each time you turn on your phone. Until a valid PIN is entered, you can use the phone only to make emergency calls.
After the PIN is accepted, the phone registers on the network and the idle screen displays.
When the PIN security feature is disabled, the phone can be used without entering a PIN.
IMPORTANT: It is recommended that you enable the PIN security feature to protect personal data on your SIM card. This prevents anyone from using your phone and accessing your personal data.
