Question

I’m trying to check if the user has enabled/disabled data roaming. All I found so far is that you can check whether or not the user is currently IN roaming, using TelephonyManager.isNetworkRoaming() and NetworkInfo.isRoaming(), but they are not what I need.

Answer 1

You can request the state of the Roaming-Switch via

ContentResolver cr = ContentResolver(getCurrentContext());
Settings.Secure.getInt(cr, Settings.Secure.DATA_ROAMING);

See: http://developer.android.com/reference/android/provider/Settings.Secure.html#DATA_ROAMING
