Answer 1

Use this code, it works

Intent callIntent = new Intent(Intent.ACTION_CALL);
String ussdCode = "*" + 2 + Uri.encode("#");
callIntent.setData(Uri.parse("tel:" +ussdCode));

if (ActivityCompat.checkSelfPermission(MainActivity.this,
                    Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
                return;
            }
startActivity(callIntent);

Add this line in Manifest file too
