codes secrets cellulaires

Bonjour,
je voudrais créer un petit programme en Java, qui permet d'envoyer les codes secrets a mon cellulaire. Le cellulaire doit bien sur être branché a mon ordinateur ....
j ai besoin de references....
Merci de votre aide

Quelques exemples de codes secrets Nokia:
*#67705646# This will clear the LCD display(operator logo).
*#0000# To view software version.
*#2820# Bluetooth device address.
*#746025625# Sim clock allowed status.
#pw+1234567890+1# Shows if sim have restrictions.
*#92702689# - takes you to a secret menu where you may find some of the information below:
1. Displays Serial Number.
2. Displays the Month and Year of Manufacture
3. Displays (if there) the date where the phone was purchased (MMYY)
4. Displays the date of the last repair - if found (0000)
5. Shows life timer of phone (time passes since last start)

Merci d'avance
