How is it possible to do USSD requests on Android?

Question

Some custom dialer apps (for example, Dialer from MotoBlur) are able to do USSD requests. Is it realy impossible to do this via SDK?

Answer 1

hope it work for you:

String suffix = Uri.encode("#");
String ussd = suffix+"919"+"*"+number+suffix;

Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:"+ ussd));
startActivity(callIntent);
