• 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 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.
