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 unauthorised 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.
• Lock code (5 digits) - The lock code can be used to lock the phone and keypad 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 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.
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.
