Call (and get the response for) a USSD Code, in the background?

Question

I\'m wanting to write a widget displays the users\' prepay balance, remaining data etc.

I\'m thinking of automatically calling the USSD code which returns this data

Answer 1

I'm not completely sure but I think USSD is not yet supported on android, however you can try this workaround:

startActivity(new Intent("android.intent.action.CALL",Uri.parse("tel:*123" + Uri.encode("#")));
