What device do you want to connect to a verizon hotspot? (model)

Most device could be connected to the hotspot, they just need to be setup correctly

Thanks so much for your reply! Inseego mifi x pro m3000. I'm not sure what I'm doing wrong. The led flashes green to red..... connected with an ethernet to the wan port.

What router do youo have? AC3800 is a speed. 

MOre than likely you’re running into a double nat issue. thats where you cascade routers. 

Usually you’d need to put the Inseego in passthrough mode or the AC3800 in access point mode to prevent the double nat. 

WC4S?

not sure if the wc4s has a access point mode you could put it in when you connect it to the inseego
