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 protects your device against unauthorised 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.
