Protecting 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. Your SIM card PIN code is given to you by your service provider.
