My Nokia E5-00 Doesn't recognize my SIM card.  What should I do?

I recently bought an unlocked Nokia E5-00.  It was brand new, but in an opened box.   Today I slid my SIM card in it, and my phone is asking me if I want to continue using it in Offline mode.  I don't use the internet on my phone, so I press no.  The phone loads normally, but I have none of my SIM card contacts, or any signal.  Is there anything I can do to get this phone to recognize that I am a T-mobile customer and let me use this phone?
