Access codes
If you forget any of the access codes, contact your service
provider.
• Personal identification number (PIN) code — This code
protects your SIM card against unauthorised use. The
PIN code (4 to 8 digits) is usually supplied with the SIM
card. After three consecutive incorrect PIN code entries,
the code is blocked, and you need the PUK code to
unblock it.
• UPIN code — This 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.
• PIN2 code — This code (4 to 8 digits) is supplied with
some SIM cards, and is required to access some
functions in your device.
• Lock code (also known as security code) — The lock
code helps you to protect your device against
unauthorised use. The preset code is 12345. You can
create and change the code, and set the device to
request the code. Keep the new code secret and in a
safe place separate from your device. If you forget the
code and your device is locked, your device will require
service and additional charges may apply. For more
