Locking the SIM Card
Your PIN (Personal Identification Number) code protects the
information stored on your SIM card. When the SIM PIN
feature is activated, you must enter your SIM card PIN code
each time you turn on the phone or insert a SIM card. Contact
your service provider for your SIM card PIN code.
Note: You can also activate your
PIN2
code, to protect secure
applications such as Fixed Dial.
