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 unauthorized 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 cellular 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 unauthorized 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. For more
information, contact a Nokia Care point or your device dealer.
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.
