Welcome to the Community

There isn't a wwan card in T450 MTM 20BUS20T0D, wwan antennas kit and the SIM card reader are there.

Lenovo approved cards for T450 and their service p/n (FRU) are:
Ericsson N5321 HSPA+, FRU 04W3842
Sierra EM7345 LTE/HSPA+, FRU 04X6014



x220 • Gobi 2000 3g | hdd, msata ssd, wwan, wifi, gps -- unique hand-made config
ThinkPad 25 Anniversary Edition. #Retro. Special. Signed by D.Hill
T470p | X1 Carbon Gen3 | Miix 2 10" | Yoga Tablet 2-1050F (Android) + BT Keyboard
ThinkPad Stack • 2.4/5 Wireless Router, HDD 1 TB, BT Speaker, Power Bank, Mobile Projector

Do it well, worse becomes itself

If the WWAN card is installed it should be shown in Device Manager, but note that the presence of the SIM card slot does not mean that the WWAN card was included when purchased.

 

  • Right-click on Start and select Device Manager
  • Left-click on Network Adapters to expand that section
  • It should be listed as a Sierra Wireless EM7345 or (possibly Ericsson N5321) if installed.

 

The Sierra Wireless card information is shown below.

FRU (part number):  04X6014  -- Sierra EM7345 LTE/HSPA+ 42Mbps M.2 Card

There is a lot of reasons the Device Manager might not show the wwan card installed. It might miss in DM completely while is present in the laptop actually. So, unfortunately, your advice, JDGillis, seems not useful.

I checked out the factory configuration, the wwan modem is missing in the OP's config.
