Access Codes
There are several access codes that are used by your
phone and its SIM card. These codes help you protect the
phone against unauthorized use.
When requested for any of the codes explained below,
enter the appropriate code (displayed as asterisks) and
press the OK soft key. If you make a mistake, press
until the incorrect digit is cleared and then continue
entering the correct code.
The access codes, except for the PUK and PUK2 codes can
be changed using the Security menu (Menu 4.5). See
“Security (Menu 4.5)” on page 82.
Important! Avoid using access codes resembling
emergency numbers, such as 911, so that you do not dial
an emergency number accidentally.
If you do not have your PIN, please contact your network
service provider. If you change any of the default access
codes, please store the new codes in a safe place for
reference. If you lose your codes, you will need to contact
your network service provider to unlock your phone.
