What do I have to do to launch phone internet settings dialog?

I have tried to set mobile data. But it just worked for only SIM 1 .

public static void setMobileData(Context context, boolean isEnabled) throws NoSuchFieldException, ClassNotFoundException, IllegalAccessException, NoSuchMethodException, InvocationTargetException {

    ConnectivityManager conman = (ConnectivityManager) context.getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);
    @SuppressWarnings("rawtypes")
    final Class conmanClass = Class.forName(conman.getClass().getName());
    final Field iConnectivityManagerField = conmanClass.getDeclaredField("mService");
    iConnectivityManagerField.setAccessible(true);
    final Object iConnectivityManager = iConnectivityManagerField.get(conman);
    final Class iConnectivityManagerClass = Class.forName(iConnectivityManager.getClass().getName());

    Class[] cArg = new Class[2];
    cArg[0] = String.class;
    cArg[1] = Boolean.TYPE;
    Method setMobileDataEnabledMethod;

    setMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", cArg);

    Object[] pArg = new Object[2];
    pArg[0] = context.getPackageName();
    pArg[1] = isEnabled;
    setMobileDataEnabledMethod.setAccessible(true);
    setMobileDataEnabledMethod.invoke(iConnectivityManager, pArg);
}

public static void setMobileData2(Context context, boolean isEnabled) throws NoSuchMethodException, ClassNotFoundException, IllegalAccessException, NoSuchFieldException, InvocationTargetException {
    final ConnectivityManager conman = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    final Class conmanClass = Class.forName(conman.getClass().getName());
    final Field iConnectivityManagerField = conmanClass.getDeclaredField("mService");
    iConnectivityManagerField.setAccessible(true);
    final Object iConnectivityManager = iConnectivityManagerField.get(conman);
    final Class iConnectivityManagerClass = Class.forName(iConnectivityManager.getClass().getName());
    final Method setMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
    setMobileDataEnabledMethod.setAccessible(true);

    setMobileDataEnabledMethod.invoke(iConnectivityManager, isEnabled);
}

public static boolean setMobileData3(Context context, boolean isEnable) {
    boolean mobileDataAllowed = Settings.Secure.putInt(context.getContentResolver(), "mobile_data", isEnable?1:0);
    return mobileDataAllowed;
}

But now I just want to launch that default mobile selection Dialog . If you have Any idea to launch that dialog let me know.. thanks in advance.

Multi SIM support is added in android lollipop 5.1 onwards only. Prior to that different phone manufacturers have their own custom implementation for supporting Multi SIM and respective settings. Hence if you are targeting for general solution it is not possible to achieve. Even on 5.1, there is no direct intent to launch this particular setting but using a hack you may achieve provided manufacturers should use only Google solution otherwise it will not work.
