Answer 1

You can use the following class: TelephonyManager http://developer.android.com/reference/android/telephony/TelephonyManager.html

You do not instantiate this class directly; instead, you retrieve a reference to an instance through Context.getSystemService(Context.TELEPHONY_SERVICE)

TelephonyManager manager = (TelephonyManager) Context.getSystemService(Context.TELEPHONY_SERVICE);
int state = manager.getSimState();
if(state == TelephonyManager.SIM_STATE_PIN_REQUIRED || state == TelephonyManager.SIM_STATE_PUK_REQUIRED)
{
         //PIN/PUK is required
}

Following the comments, this is the final version:

TelephonyManager tm = 
(TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
       Class clazz = Class.forName(tm.getClass().getName());
       Method m = clazz.getDeclaredMethod("getITelephony");
       m.setAccessible(true);
       ITelephony it = (ITelephony) m.invoke(tm);
       if(it.isSimPinEnabled())
       {
                //This should work;
       }

As getSimLockEnabled always returns false for me, i had to find another way to do it.
