The latest BIOS update for T450s contains:
* (Fix) Fixed an issue related to WWAN lost when USB3.0 enabled.

I haven't updated my bios yet, but I tried to disable USB 3.0.
Unfortunately it did not help much. Card appears randomly after reboot
and removing modules does not help.

Title:
  nm-applet is missing the Sierra EM7345 4G LTE

Status in network-manager-applet package in Ubuntu:
  Confirmed

Bug description:
  The current system Ubuntu 15.04 Beta2 (up2date) is missing the nm-
  applet after restarting the system.

  It might be a problem with the Sierra EM7345 module?!
  After the new install of Ubuntu 15.04 Beta2 i saw the Sierra for one or two times inside the nm-applet and i could create a mobile-data connection over HSDPA/UMTS/LTE. But just for this time.

  Now, after some regular updates, the Sierra Card is not accessable
  inside the nm-applet menu for creating a new mobile data connection,
  the old connection profil is missing too. The Sierra EM7345 was also
  named as cdc-wdm not by name.
