Sony Ericsson m608c Betriebsanweisung

Your PIN (Personal Identification Number) 
code consists of four to eight digits and is used 
to protect your SIM card against unauthorized 
use. It is needed for the access of the SIM card. 
You get it from your operator with the SIM 
card, but you can change it in the 

 menu. 

Your 

 setting options are:

•

 – you will be requested to 

enter your PIN code every time you turn 
the phone on.

•

– the lock is turned off; no code will be 

requested.

An error message informs you if an incorrect 
PIN code has been entered. Usually, the SIM 
card will be blocked after three incorrect 
attempts (the number of attempts is operator-
dependent). To unblock the SIM card you must 
use your PUK code.
The PUK code consists of eight digits. When 
you have entered the right PUK code you must 
enter a new PIN code. You have ten attempts 
to enter the PUK code. If all ten attempts fail, 
the SIM card will be unusable and you need to 
contact your operator. You cannot change the 
PUK code.

Some special SIM card services, such as Call 
meter and Fixed Numbers, can be protected by 
a secondary code feature, the PIN2 code. The 
code properties are:
•

 cannot be disabled, but the four-to-

eight digit code can be changed in the 

menu.

•

 will be blocked after three incorrect 

attempts. To unblock the code, a PUK2 
code must be entered.

• After 10 unsuccessful PIN2 unblocking 

attempts, the card can still be used, but 
access to the PIN2-protected SIM features 
is permanently barred. 

• Not every SIM card has a PIN2 lock.

If you mark the 

 check box and 

enter the requested 

 code, this lock 

will be activated. It protects the screen from 
accidentally being pressed. The screen will 
automatically become locked after a 60-
second period of inactivity. To open it, touch 
any key to bring up a dialog where you must 
enter the 

 code.
