E5570 LTE Sim Card not recognized

Hi Everyone,

i havent been able to find a solution on the web about the issue i am experiencing,

The issue is following:

The Notebook has a SIM Card Slot and we installed a Sim in it, installed the current Driver and everything. Unfortunatly i am not able to Access it in any way. It doesn't Show up on the WiFi networklist at all.

So i cant even unlock it with the pin.

Anyone have a succetion i might try?

Thanks in andvance.
