To know the USSD commands sent by a SIM Application

Hello!

I am testing how to send USSD with my GSM modem.
There is a USSD number dedicated for checking my credit balance (#123#).
But my mobile operator doesn't give us a number for checking other USSD services like weather forecast, horse show results, etc. They are included in the SIM-based applications.

So, is there a way to find out the USSD numbers used in these services?

In fact, I'm looking a tool like: http://www.comprion.com/index.php?mySID=c524b7e0ae56849ad30caab0588b77e9...

The goal is to spy the communication between sim card and the phone to discover the composed ussd commands.
