8 Unblocking
If the phone is disabled due to a wrong entry of the phonecode (not PIN1, PIN2,
network code or service provider code!) it can only be resetted by entering the right
unblocking code.
This unblocking code is derived from the IMEI number of the mobile and can only be
calculated in two different ways:
8.1 Siemens Hotline
You can retreive the code from our hotline personell in Germany.
If you need unblocking codes just send a fax with the IMEI numbers to:
Siemens AG
PN MP SH
World Service Center
Bocholt, Germany
Fax: +49 2871 91 3007
Please use the appropriate form provided by your Siemens service coordinator.
