I am trying to configure the USSD service using my iPhone. But I want the uSSD connection to be live in the background (it does not have a gray popup when connecting to USSD). The USSD connection will be coming in because I will not initiate it, and currently it is automatically opened by the phone, bringing me to the gray menu.
I want to basically not have this popup menu, and my program sends some information on the USSD connection programmatically to the source of the USSD connection. I know that there is no USSD API, but how can I basically read USSD #, which calls me, and then basically send back the data that I want through the uSSD tunnel that install the program.
As mentioned earlier, I can already automatically receive a uSSD connection. I just need to "run in the background" and then programmatically send something back.
