Protecting the SIM Card

You can use a Personal Identification Number (PIN) 
code to protect the information stored on your SIM 
card even when it is inserted into someone else’s 
phone.

When you activate the SIM card PIN code, your 
phone requests the code whenever the phone is 
powered on. To change this setting, you need to 
enter the PIN code that your service provider gave 
you.
