PIN (Personal Identification Number) code (4 to 8 digits) protects your SIM card against 
unauthorised use. The PIN code is usually supplied with the SIM card. After three 
consecutive incorrect PIN code entries, the PIN code is blocked, and you need to unblock 
it before you can use the SIM card again. See the information about PUK code in this 
section.
UPIN code may be supplied with the USIM card. The USIM card is an enhanced version of 
the SIM card and is supported by UMTS mobile phones. The UPIN code protects the USIM 
card against unauthorised use.
PIN2 code (4 to 8 digits) supplied with some SIM cards, is required to access some 
functions in your phone.
Lock code (5 digits) can be used to lock the phone to avoid unauthorised use. 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 (Personal Unblocking Key) and PUK2 codes (8 digits) are required to change a 
blocked PIN code or PIN2 code, respectively. If the codes are not supplied with the SIM 
card, contact the operator whose SIM card is in your phone.
UPUK code may be supplied with the USIM card and is needed to unblock a UPIN code.
Wallet code is needed to use the wallet services. See Wallet, p. ’75’.
