EM7355 to German Vodafone does not find any Connection


I bought an EM7355 at Ebay for my Panasonic CF-53 MK4.
It could be installed on windows 10 but windows always reports “No connection”
Provider is Vodafone Germany.
Do I have to update the card firmware? If yes, how does it work?

Thank you for your help.

Did you install usb driver?


Here is the firmware:
