HP EliteBook 840 G4
Microsoft Windows 10 (64-bit)

I purchased my new laptop i.e. HP EliteBook 840 G4 and there is a SIM slot on the right side of the laptop. How would I know that the SIM slot is working because I inserted a SIM and it did not work. I checked the device manager and found a slot with the name other devices SIM/MMS without any driver. Unfortunately I did not find any driver for this device anywhere. I already tried installing LTE and broadband drivers but in vain. Please help
