General information
■ Access codes
For specific settings of Access codes, see 
• Security code (5 to 10 digits): The security code protects your phone against 
unauthorised use, and is supplied with the phone. The preset code is 12345. 
Change the code, and keep the new code secret and in a safe place separate 
from your phone.
• PIN code and PIN2 code (4 to 8 digits): The PIN (Personal Identification 
Number) code protects your SIM card against unauthorised use. The PIN code 
is usually supplied with the SIM card.
The PIN2 code may be supplied with the SIM card and is required to access 
some functions, such as charging unit counters.
If you key in an incorrect PIN code three times in succession, the phone may 
display 
PIN code blocked
 and ask you to key in the PUK code. Contact your 
service provider to get the PUK code.
• 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 your local service 
provider for the codes.
