Not sure if having my Note 8 factory unlocked by Sprint helps as b727pilot stated but mine is because it's been paid off and automatically unlocked by Sprint.
But all I did is copy ALL of the APN info from the default APN2 LTE|EHRPD internet settings and added ".dun" to the end of APN type into a new one that's named exactly the same thing too.
I did notice one thing that I don't see posted on here since I've done this. Also please do note that my phone is NOT rooted and is updated to the latest Android update from Sprint. Once I switch over to the newly copied APN, which is directly under the original one, I can no longer receive or send MMS messages to anyone, including the other line on my Sprint account. Not sure if this is gonna happen to you or not but it does with me. So basically once I'm done using the hotspot till my hearts content, then I switch the APN back to the original default one and instantly I'm able to use MMS again with no ill effects.
Not sure also, but I DON'T have to restart my phone for any reason or use any hidden codes when switching between the default and modified APN settings. I just switch it back and forth without any issues. I tracked my hotspot usage on the Sprint app and have confirmed beyond a reasonable doubt that this does in fact record all hotspot usage under the phone's data usage and nothing under the "hotspot" data usage on my account. I downloaded about 10 gigs of video and it updated under my phone's data usage and my hotspot usage remained exactly the same as it did before I downloaded anything.
So happy unlimited hotspotting to everyone!
