So I don't have access to WiFi at the moment. So I can't connect my phone and Xbox to same WiFi network in order to screen cast to it. The only thing I have right now is 15gb hotspot each month. And I'm pretty sure I've exhausted every possible method for that and my conclusion is it's not possible to screen cast with one phone and it's hotspot and an Xbox. So there is no chance of wifi until I go back home in January. Is there any sort of dongle I could use to use my unlimited LTE phone data to cast to that or something so I can screen cast?
