One more info:

I tried to call the *#100# number to receive a USSD message with my phone number, but that didn't work. Intead, I received a message with a "Service Unavailable". Any hint?

Thanks,

Hi list,

Is there a tutorial in how to make a USSD application work in a OpenBSC network?

Firstly I'm want to implement a simple "Hello World" application. eg. the client enter with a valid USSD number (*something) and the "Hello World" application executes.

Best Regards,
