Hate to tell you foxfi won't do this there is a way to do this but you will need Google it for this phone under WiFi feather and you should find it.
There are third party apps that allow any android to be used as a mobile hotspot, such as FoxFi. Using third party apps to turn your phone into a mobile hotspot allows you to circumvent monthly "hotspot plans" that other carriers charge.
