If not supplied with your SIM card or you forget the codes,
contact your service provider.
If you enter the code incorrectly three times in a row, you need
to unblock the code with the PUK or PUK2 code.
PUK or PUK2 code
(8 digits) These are required to unblock a PIN or PIN2 code.
If not supplied with your SIM card, contact your service provider.
IMEI number
(15 digits) This is used to identify valid devices in the network. The number
can also be used to block, for example, stolen devices.
To view your IMEI number, dial *#06#.
Lock code (security
code)
(min. 4 digits or
characters)
This helps you protect your device against unauthorized use.
You can set your device to ask for the lock code that you define.
Keep the 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.
The personal unblocking key (PUK) code and the universal personal unblocking key
(UPUK) code (8 digits) are required to change a blocked PIN code and UPIN code,
respectively. The PUK2 code (8 digits) is required to change a blocked PIN2 code. These
codes are not supplied with the SIM card. Contact your local service provider for the
codes.
