No SIM installed

I am using this USB modem with an AT&T SIM card connecting to a Panasonic Toughbook CF-31 Windows 7 64 bit Enterprise and when I initlally connect the device to the laptop it will connect but after 20 minutes or so the display on the modem shows No SIM Installed. I have tried multiple USB modems but get the same error. Do you think this the actual SIM card failing?

    Hello daveym

     

    If you are getting the same error on multiple modems then yea I would say its a issue with the sim card.
