SIM Card Security

Your SIM card stores all your Contacts and
protects your personal information. Since this
information is stored on your SIM card, not in your
phone, you can remove the information by
removing your SIM card.
Note: Except for making emergency calls, your
phone will not function without the SIM
card.
To prevent unauthorized use of your phone, your
SIM card can be 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.
Turning the PIN Requirement On and
Off
When the SIM PIN requirement is off, your phone
can be used without entering a PIN.
Important: When the SIM PIN requirement is off,
the personal data on your SIM is not
protected. Anyone can use your phone
and access your personal data.
