Mobile broadband on windows 10 64 bit

Hi,

I have a Dell Latitude E7270 and the mobile broadband is not working. I can't see anything related to mobile broadband in windows.According to some research there should appear "Cellular" tab in "Network & Internet", but can't see anything. 

There is a slot for sim card and I I believe I have downloaded all drivers. 

"Intel Wireless gigabit user mode" in device manager is the only one that obviously fails: "Windows has stopped this device because it has reported problems. (Code 43)".

Dell Mobile Broadband Manager is not installed and I can't find a version for windows 10 64 bit. 

Could you please guide me in the correct direction to install any key drivers or software?

Br,
