After three consecutive incorrect PIN code entries, the PIN code is blocked. If the PIN 
code is blocked, you need to unblock the PIN code before you can use the SIM card 
again. See the information about the PUK code.
• PIN2 code (4 to 8 digits) - The PIN2 code, supplied with some SIM cards, is required 
to access some functions, such as call cost counters.
• Lock code (5 digits) - The lock code can be used to lock the phone and keypad to 
avoid unauthorised use. 
Note: The factory setting for the lock code is 12345. To avoid unauthorised 
use of your phone, change the lock code. Keep the new code secret and in a 
safe place separate from your phone.
• PUK and PUK2 codes (8 digits) - The PUK (Personal Unblocking Key) code is required 
to change a blocked PIN code. The PUK2 code is required to change a blocked PIN2 
code. If the codes are not supplied with the SIM card, contact the operator whose SIM 
card is in your phone for the codes.
You can change the following codes: lock code, PIN code, and PIN2 code. These codes can 
only include the numbers from 0 to 9. 
Note: Avoid using access codes similar to the emergency numbers, such as 112, 
to prevent accidental dialling of the emergency number.
PIN code request
 - When the PIN code request is active, the code is requested each time 
the phone is switched on. Note that deactivating the PIN code request may not be 
allowed by some SIM cards.
