I got my x240 a couple of days ago and am trying to get the wwan card to work. What rule is needed for udev? And did you get the gps function to work as well?

I had to add the following line to /lib/udev/rules.d/77-mm-ericsson-mbm.rules for the Ericsson N5321 WWAN adapter:

ATTRS{idVendor}=="0bdb", ATTRS{idProduct}=="193e", ENV{ID_MM_ERICSSON_MBM}="1"

To be sure what vendor and product ID to use, you should check that first via 'lsusb|grep Ericsson'.

I did not care about GPS yet.
