Configuring SIM card in latitude E5440

I have seen a sim card slot after removing the battery. So, I connected a sim card. But It doesn't work. What can I do to turn it on?

The SIM card socket is part of the motherboard and will exist whether or not the laptop is ordered from Dell with a mobile broadband option. There are multiple parts to mobile broadband in a laptop (1) SIM card, (2) antenna system, (3) a WWAN broadband adapter (card) the antennas connect too, and (4) drivers and application software. The drivers section for your laptop at dell.com has listings for 5 different WWAN cards: the DW5570, DW5808, DW5808e, DW5809, and DW5809e. Is one of these cards listed in Device Manager > Modems or Network adapters? Does Device Manager have a category called Others with something like communications device listed?
