How to have access to contacts saved on SIM card.

Hello Everyone,

I am trying to get all contacts that are present on my Windows MObile phone and ON SIM Card.
By writing following simple code, I got all the contacts from my Windows Mobile Phone native address book.

ContactCollection contactCollection = null;
Contact contact = null;
OutlookSession outlookSession = null;
outlookSession = new OutlookSession();
contactCollection = outlookSession.Contacts.Items;

But this contactCollection does not include contacts that are stored on SIM Card.
If anybody knows how to access contacts stored on SIM card or any work around the please reply ASAP.

Thanks and regard
RaJ
