Can a mobile broadband box (links inside) be used as a network extender or a router?

Specifically I would want to connect it to Public Wi-Fi (for the time being) which I pay for so that I can connect all my WIFI enabled devices and link them together which as you know can't be done on a public wifi. It does obviously have a network login page so I don't know if that would make it harder. I do know actual router's are cheap but if I avoid spending money (even small amounts) then why not. Also I have no spare device that I can just leave a hotspot on and I don't want to make a hotspot of my laptop or phone because they are constantly leaving and returning to the home.

I'm guessing no because I'm assuming they are designed in such a way - *what ever I mean by that* - however I could not find anything online about it so I thought I would I just ask here for conformation, thanks.
