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 the key 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 Security menu
options (Menu 4.6). See page 84 for further
details.
Important! Avoid using access codes resembling
emergency numbers, such as 911, so
that you do not dial an emergency
number accidentally.
