Any way to use 4g?

I have 2 Verizon USB 4g Modems and was hoping to find a way to use them with the X2. I see a settings option for Cellular Network but when I click it just brings me back to man menu.

Unfortunately none of our devices support USB network adapters. You will need t either use a standard WIFI connection or an Ethernet connection with Webcaster X2.

I apologize for the inconvenience
