T420 sim card

Hello everybody!

I have a question about the WAN. I inserted my sim card in the card reader in my thinkpad t420, but it didn't find the new network connection associated with the sim.  Is there a driver to be downloaded/upgraded to be able to use my laptop on the internet, or do I have to configure something?

P.S. I'm using Windows 10...

Re: T420 sim card

Does your T420 have the WWAN card installed?  Just because it has a sim card slot does not mean laptop comes with WWAN card.  What is your specific MTM(Model Machine Type) ?  Not all models came with WWAN.
