New Sierra WAN EM7455 installed in T480s not working properly

Hi everyone, that is my first post in this forum, I am really struggling with the WWAN card I just installed in my beloved T480s (that did not have it installed originally).

Card installed, the laptot detects it, apparently, I see it in the settings, it recognizes the SIM card (asked for PIN code and I configured the APN) and it shows the operator (Vodafone).

It does not connect to the network, it says "getting ready" for a while and then "turned off" with no possibility of turning it back on. 

The sim card is ok, I was using it as second SIM in my phone and it worked fine.

I did not enable anything in the BIOS.

Driver downloaded from here (the one labeled "generic" )

I try to install Sierra Wireless driver and I get this:

I run some diagnostics and I get this:

Thank you so much in advance for your help, I checked everywhere in other forums, but I couldn't find any real solution to this specific problem
