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 unauthorised use.
You can set your device to ask for the lock code that you define.
The default lock code is 12345.
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.
