Hello and welcome,


Have you verified that your laptop has a WWAN card installed?  They  all have SIM slots but not all have a WWAN card - that can use the SIM card.


What is the MT-M of your machine?  (Like 1234-XYZ)  The MT-M lookup feature of support is currently turned off but we may be able to track down the specs.
