It seems to be until you reboot you must perform this trick. I running the midnight rom if that makes a difference here which it may. First get Check out

Next is hardest the phone has to be on 3g but still have LTE enabled, for those of you in well covered LTE areas this probably won't work.
Now when on 3g only open root app uninstaller and remove Samsung DM service and then com.sec.MSC.nts.android.proxy
You should now be throttle free on 3g and LTE until you reboot. When you reboot restore the two apps in app remover and then start from the beginning.
Hope this helps someone else!
