Mini Connect Cellular Firmware

I have a new Verizon SIM card inserted into my IT-MINI-Connect and it will not connect to the cellular network. I have tried the SIM on a different device and it connects. I am trying to update the modem firmware but keep getting and error. Does anyone know where to download the firmware so I can update it manually?

At this time, it is not possible for cell modem firmware to be updated on the Connect IT Mini.

Did you try manually entering the appropriate APN within the settings of the device?
