Security
The Security feature enables you to restrict the
use of your phone by others and to restrict the
types of calls.
Various codes and passwords are used to protect
the features of your phone.
1. From the Home screen, press Menu ➔
Settings ➔ Phone ➔ Security.
2. The following options are available. Use
the Up or Down Navigation key to scroll to
and set options:
Lock Phone
When the Phone lock feature is enabled, the
phone is locked and you must enter the 4- to 8-
digit phone password each time the phone is
switched on. The first time you access this
feature, you are prompted to enter a new
password. Remember this password, because
you will be required to enter it the next time you
access this feature.
The following options are available:
• On: You are required to enter the phone password
when you switch on the phone.
• Off: You are not required to enter the phone
password when you switch on the phone.
Note: When you create or change your password,
be sure to write it down and keep it in a safe
place. If you forget your password, your
phone will require AT&T customer service to
have it unlocked.
Lock SIM Card
When the SIM Lock feature is enabled, your
phone only works with the current SIM. You must
enter the SIM lock code to unlock the SIM so you
can use a different SIM card. The first time you
access this feature, you will be prompted to
enter a new password. Remember this password
because you will be required to enter it the next
time you access this feature.
The following options are available:
• On: You are required to enter the SIM lock code
when you switch on the phone after replacing the
SIM card.
• Off: You are not required to enter the SIM lock code
when you switch on the phone after replacing the
SIM card.
Note: This lock code is typically the last four digits
of the current phone number or can be
obtained from an AT&T customer service
representative.
