Windows 10: my doesn't have cellular data but has sim slot

Sim slot available but no cellular network settings

I have a Lenovo Thinkpad T440p, there's a sim slot available where the battery is but on the system there are no settings for cellular/sim network.

I am up-to date with updates and even updated all network drivers individually under Device Manager.

Under Network Connections I only have Bluetooth, Ethernet and Wi-Fi.

The system is operating on Windows 10 64bit, 4gb RAM.

Why am I not getting the option for Cellular Network even though there is a sim slot?

 

Cellular Disconnected

I have a cellular modem in my Dell Precision 3520. I used it Friday without any problems at all. Today, as I'm at work, I cannot connect to AT&T's cellular network.

When I click the network icon in the system tray, it shows my cellular connection as "AT&T (HSPA)" and then reads "Disconnected" underneath it. It shows 5 bars. If I open network properties and try to troubleshoot the adapter, it gives me a SIM2 error that says I need to enter a PIN code (there is no PIN code on the SIM card, but just for troubleshooting purposes I added one, still got the same error, and then ultimately removed it again).

Things I have tried so far:

• Toggling cellular on/off
• Rebooted computer (several times)
• Uninstalled and reinstalled the driver (twice)
• System restore to the point where it was working the other day
• Ejecting the SIM card and reinserting it
• Verifying that data is turned on with my AT&T count
• Enabling/disabling PIN code
• Resetting network settings via command prompt
• Creating a new APN (with phone, NXTGENPHONE, etc.)

Any tips?
