Getting Started
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 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.
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 card is
not 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.
Note: If a SIM PIN is required, your phone will
not function until the SIM PIN is entered,
except for making emergency calls.
1 From the main menu, select Settings >
Security > SIM PIN.
2 Select On or Off.
3 Enter the current SIM PIN.
Note: The default SIM PIN is 0000. Change your
PIN to prevent fraudulent use of the SIM
card (see “Changing the PIN” on page
13).
