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, key in the appropriate code (displayed as
asterisks) and press the OK soft key. If you make a
mistake, press the
key one or more times 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 80 for further
details.
Important! Avoid using access codes resembling
emergency numbers, such as 911, so
that you do not dial an emergency
number accidentally.
Phone Password
The Phone Lock feature uses the phone password to
protect your phone against unauthorized use. The
phone password is supplied with the phone and is
factory set to 00000000.

PIN
The Personal Identification Number or PIN (4 to
8 digits) protects your SIM card against unauthorized
use. It is usually supplied with the SIM card.
If you enter an incorrect PIN three times in
succession, the code is disabled and cannot be used
until you re-enable it by entering the PUK (see
below).
PUK
The 8-digit PUK (Personal Unblocking Key) is
required to change a disabled PIN. The PUK may be
supplied with the SIM card. If not, or you have lost
it, contact your service provider.
To re-enable your PIN, proceed as follows.
1. Key in the PUK and press the OK soft key.
2. Enter a new PIN of your choice and press the
OK soft key.
3. When the Confirm New PIN message is
displayed, key in the same code again and press
the OK soft key.
If you enter an incorrect PUK ten times in
succession, the SIM card becomes invalid. Contact
your service provider for a new card.
