T450s WAN Port. how to use?

[BobbyKa]

I bought a used T450s. In Device Manager I see the WAN. So i guess the module is installed and it is not only a preinstalled Sim tray.
Installed both the Sierra and Ericcson drivers from Lenovo website. In BIOS the WAN is enabled. SIM is installed. But don't see where to type in the PIN or start connection.
Any clues what i am doing wrong?

What you are missing is the WWAN adapter

Hmmm..... So it ain't enough to cut a cord to make it "w"?
Seems I didn't saw the obvious.
