I have recently bought an Elitebook 840 G3, which has a built-in SIM card slot. I've successfully inserted the Virgin Micro SIM from my mobile phone, but it doesn't work. I took the advice of this forum to download the mobile broadband drivers, which was sp74017.exe, but when I tried to install it I got messages to say it was already installed, so I cancelled the install. 

I've searched in the list of available wireless sources, but it is not listed.

I know it works as a broadband device, as I also have a T-Mobile 3G dongle. I've put the SIM card in this and it works fine. I was hoping, however, to avoid having to use one of the two USB ports for the dongle and to make my laptop a little more streamlined by using the built-in SIM card slot instead.

How can I activate this siim card?
