Hi all, I need some help. Purchased an HP Elitebook 840 G3 and added the HP LT4120 wwan card. I made sure the drivers are up to date and the BIOS is updated. However when I have the SIM inserted Windows detects the SIM card shows 'no service' and reads all the information but does not populate the IMEI. When I open Verizon Connection Manager it does not show a SIM is inserted.
