• SECURITY

Phone and SIM
Explanations for the different security codes that may be needed:
• PIN code (4 to 8 digits) - The PIN (Personal Identification Number)
code protects your SIM card against unauthorized use. The PIN code
is usually supplied with the SIM card. 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 unauthorized use.
Note: The factory setting for the lock code is 12345. To avoid
unauthorized 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.
