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 - 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 3G mobile phones.
• PIN2 code — This code (4 - 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. Additional charges may apply,
and all the personal data in your device may be deleted.

• Personal Unblocking Key (PUK) code and PUK2
code — These 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 network
service provider whose SIM card is in your device.
• UPUK code — This code (8 digits) is required to change a
blocked UPIN code. If the code is not supplied with the
USIM card, contact the network service provider whose
USIM card is in your device.
• International Mobile Equipment Identity (IMEI)
number — This number (15 or 17 digits) is used to identify
valid devices on the GSM network. Devices that are, for
example, stolen, can be blocked from accessing the
network. The IMEI number for your device can be found
under the battery.
