Description of problem:

My 2014 x1 carbon has s wwan card, which worked like a charm in fedora 20. Now NetworkManager does not detect the card. I can see the card with lsusb:

I was able to solve running as root:

systemctl start ModemManager

and permanently by running:

systemctl enable ModemManager

I am sure that this service has always been enabled by default... hasn't it?

This may be an issue with upgrade. Can you tell us how you upgraded to F22? From what version?
It is a duplicate of bug 1227424.
