Security code
The security code is required by some security features, 
including phone security (see page 67). It comes with your 
phone. The default security code is 12345. Use 
Menu

3 to change it. Keep the new code secret and in a safe place, 
separate from the phone.
When the phone requires the security code, it displays 
Security code:
 Enter the code, then press 
OK
.
If you enter an incorrect security code five times in a row, 
the phone will not accept the correct code for the next five 
minutes.

PUK and PUK2 codes
The PUK (Personal Unblocking Key) may be supplied with 
your SIM card. If not, contact your service provider for the 
code. The code is required to change a blocked PIN code.
If you enter a wrong PUK code ten times in succession, the 
SIM card becomes invalid. Contact your service provider for 
a new card.
The PUK2 code, supplied with some SIM cards, is required to 
change a blocked PIN2 code. If you enter a wrong code ten 
times in succession, you can’t use the functions requiring 
the PIN2 code. Contact your service provider for a new card.
You can’t change the PUK or PUK2 code. If you lose it, 
contact your service provider.
SIM card security
You can set the phone to require the PIN code every time 
you switch on the phone. Note that some SIM cards do not 
allow this feature to be turned off.
