Answer 1

The code below is much more simple and tested on Gingerbread (2.3.7) and JB (4.1.2)

    startActivityForResult(new Intent(android.provider.Settings.ACTION_DATA_ROAMING_SETTINGS), 0);

Answer 2

try as:

final  Intent intent=new Intent(Settings.ACTION_DATA_ROAMING_SETTINGS);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
 final ComponentName cn = new ComponentName("com.android.phone","com.android.phone.Settings");
intent.setComponent(cn);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
