SIM Security
Your SIM stores all your Contacts and protects
your personal information. Since this information is
stored on your SIM, not in your phone, you can
remove the information by removing your SIM.
Note: Except for making emergency calls, your
phone will not function without the SIM.
To prevent unauthorized use of your phone, your
SIM is protected by a PIN that you enter each time
the phone is powered on. You can change the PIN
or turn off the requirement that it be entered.

Off

protected. Anyone can use your phone
and access your personal data.
When the SIM PIN requirement is on, you are
prompted to enter your PIN each time you power
on your phone.
