I followed Rob's advice and still having the same issue
I can only get the Toughbook to recognize the card if I have the dip switches on WWAN1 and WWAN2
The card will NOT detect at all when set to WWAN3
I still however have the issue whereby the card only installs the COM11 device and causes device manager to flicker constantly as if it is refreshing for the installation of another component but it never does

I can't see as there is another way forward, is it time to contact the seller and get a refund stating that it is faulty or is there something else I can try?
Thanks guys
