Phone and SIM
If your phone requests a security code, refer to the following explanations to
determine what you should enter. If you forget or lose a PIN or PUK code or if you
have not received such a code, contact your service provider.
You can change the following codes: lock code, PIN code, and PIN2 code. These
codes can only include the numbers from 0 to 9.
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 service provider for the codes. The PUK
and PUK2 codes are 8 digits long.
Avoid using security codes similar to emergency numbers, such as 911, to prevent
accidental dialing 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.
• PIN code (4 to 8 digits)—The PIN 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 also the information below about the PUK code.
• PIN2 code (4 to 8 digits)—The PIN2 code is supplied with some SIM cards and
is required to access some functions, such as fixed dialing numbers (FDN).
• Autolock period—You can set an autolock period, a time-out after which the
phone is automatically locked and can be used only if the correct lock code is
entered. Key in a number for the time-out in minutes, or select None to turn
off the autolock period.
To unlock the phone, key in the lock code.
When the phone is locked, calls may still be possible to the official emergency
number programmed into your phone.
•
Lock code (5 digits)—The lock code can be used to lock the phone and keypad
to avoid unauthorized use. The factory setting for the lock code is 12345. To
prevent unauthorized use of your phone, change the lock code. Keep the new
code secret and in a safe place separate from your phone. If you forget or lose
the lock code, contact your service provider.
•
Lock if SIM changed—Select Yes if you want the phone to prompt for the lock
code when an unknown, new SIM card is inserted into your phone. The phone
maintains a list of SIM cards that are recognized as the owner’s cards.
