Internet sharing on T-Mobile (US) - has anyone gotten it to work with the ATIV S??

Tried following the instructions on the similar AT&T internet sharing thread, downloaded (both) Samsung APN apps, tried a variety of apn settings (epc.tmobile.com, fast.t-mobile.com, pcweb.tmobile.com) but can't seem to get internet sharing to work! I called T-Mobile and they confirmed that, on their end, I DO have Hotspot active and enabled on my account ($60/2GB monthly paid). I have 4 bars of 4G service and data surfing works no problem on the phone. However, everytime I try to turn Internet Sharing on, it churns for a few seconds but then it gives the message: "Connection not shared. There's no cellular data connection to share right now. Check your cellular settings and signal, and try again.". Yet I do have a signal (and this is also with Wifi turned off).

Any suggestions/advice? Pulling my hair out trying to get this to work on TMobile...

I've been unable to get this to work regardless of fiddling with settings and/or the hidden Diagnosis app. I suspect that IF we could use the Diagnosis app to remove the carrier specific customization from the phone to make it a fully "unbranded" phone this should work, as the phone is likely looking for some kind of Telus (in my case) server to authenticate hotspot permissions, but I'm unwilling to fully reset my phone using the Diagnosis app CSC settings to try to find out if this will work or not. If anyone figures this out I'd love to hear the solution.

I just took the plunge and answered my own question. After doing the CSC change to FMC (Fido) using the Diagnosis app, INTERNET SHARING ON T-MOBILE JUST WORKS!!! So look up the thread on this forum on how to do a CSC change, choose FMC, and go for it. I have no idea whether this screwed me for future GDRx updates or not, but guess I'll cross that bridge when I get there.

Spoke too soon. Choosing Fido disables LTE. Now trying Bell and will also try Rogers, see if any of those have the magic combo of LTE AND Internet Sharing.

If you're willing to live without LTE, at least for me the Fido CSC setting was the only one which seemed to get Internet Sharing working.

starting to think Internet Sharing gets disabled when you unlock a device... I'm on Bell Mobility and have an unlocked Rogers ATIV S and everything works flawless EXCEPT Internet Sharing.
