I do not know if this works without root, or any other provider. I use boost mobile. Worked on my Samsung galaxy prevail LTE without root though. Very simple process. First you will need to download an app called "Change APN" from the play store. Open app and inside there are two access point names that needed edited. APN2 EHRPD internet and APN2 LTE internet. Inside of these AP is a section called APN type. Inside here you need to add ,Dun so they will look like this. "default,mms,Dun" without quotes. Shutdown phone and power back on. Once done start hotspot like normal in setting and boom. I did need to reset my phone twice before it worked but did start working. Hope this helps anyone else and enjoy.
