Enabling and Disabling SIM PIN
The SIM PIN option enables and disables the feature that requires a SIM PIN
code to be typed into the phone to access the information on the SIM card and to
make or receive calls. See "SIM Card Personal Identification Number (PIN)" on
page 15 for more information.
Setting New Passwords
The New Passwords option enables you to set three types of passwords that
control access to your phone:
• Unlock Code — this code is used to control access to the phone using
Phone Lock. It is also required to access the Master Clear and Feature
Reset features. If you want to use any of these features, contact Nextel
Customer Care for your default Unlock code.
• Security Code — this code is used to access the Master Reset feature
under the direction of a Nextel Customer Care Representative. It can also
be used to override your Unlock code under the direction of a Nextel
Customer Care Representative.
• SIM PIN — this code is used to access the information on your SIM card
and to make or receive calls. When you get your phone, your SIM PIN is
0000. You should change this to a SIM PIN known only to you as soon as
you get your phone. For information on changing your SIM PIN, see
"Changing the PIN" on page 18.
