GSM network codes
Some characters explained
| * | activate |
| ** | register and activate |
| *# | check status |
| # | unregister |
| ## | unregister and deactivate |
The codes are used by for example writing ##002# and the pressing the key corresponding to "Send". There are some codes where you are not supposed to press "Send". These codes are only to be used within the phone itself and they don't take any use of the net services.
Not all codes are functioning in all nets. It depends on what the operators have included in their software.
If a phone number is expected you should enter it in the international format e.g. +4412345687. This will always do the trick whatever net you are logged in to.
The codes are divided into different categories:
Safety
Call barring
Call forwarding/diversion
Number presentation

GSM network servicecodes
Attention! only 11, 13 and 25 are functioning today. Maybe later you willbe able to use all these codes to monitor every single of the commandsabove by entering the service code just before the last # on the command line. If you wish to divert all data calls to another PhoneNumber, you'll enter the command '*21*PhoneNumber*12#
