General Network Service Commands - GSM Commands - Learn Latest Computer And Mobile Hakcing Tricks

There are some pre-programmed network commands under “SIM Services” options in mobilephones. When various “Network services/SIM Services” functions are selected, the phone generates and transmits the corresponding network command. However besides “SIM Services, there are many other commands as well, that can be manually entered and executed.
Generally every command is prefixed with either one or two *(Star Key) or #(Hash Key) as follows:
* Activate
*XYZ* Register and Activate
#XYZ# De-Register (and Deactivate)
# Deactivate

*XYZ# Check Status (Where XYZ is a certain number varying from network to network)
© Call Key/Green Key/OK Key
NOTE that most of the commands given are network service provider dependent and you should contact your service provider for codes if any code does not work.

To execute, each command has to be entered/pressed at idle screen and must be sent to the network by pressing “Call/Yes/OK/Green Key” which is represented here with the © character. Remember to enter numbers in full international format wherever required like for example “ + Country Code then area code etc (+91567890123)
