4.5 Protecting your Phone

There are several levels of security on your phone. You can protect your
phone from unauthorized use by requiring a type of password called a PIN
(personal identification number) in order to make calls. Your first PIN will be
given to you by your wireless service provider. Additionally, you can lock the
keypad or the entire phone to prevent unauthorized access.
To enable the SIM/USIM personal Identification number (PIN)
1. On the Home screen, click Start > Settings > Security.
2. Click Enable SIM PIN.
3. Enter your PIN, and click Done.
Note

To change the SIM/USIM PIN
Be sure to make a note of your personal identification number (PIN). When
the SIM/USIM PIN is enabled, you must provide this PIN to unlock the
phone.

if, for example, the phone is turned on and in your pocket, and you want to
prevent accidental keypresses.

Once the keypad is locked, the left soft key label changes to Unlock.
To cancel without enabling the SIM/USIM PIN, press HOME.
