Launching mobile network settings screen programmatically

They won't work because there was a bug that was fixed I think in 2.3.

See https://review.source.android.com/#/c/22229/

You can bypass this using (for NETWORK_OPERATOR_SETTINGS)

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.android.phone", "com.android.phone.NetworkSetting");
startActivity(intent);

Replace NetworkSetting with Settings for DATA_ROAMING_SETTINGS

there's another similar solution described in Error opening mobile network settings menu

UPDATE

I recently tested this and it seems that this workaround is still necessary up to API level 15. Since API level 16 the intents in the question seem to work correctly.
