BYOD Unlocked AT&T HTC One M9 can't do Hotspot

magenta2648245

    I have an unlocked AT&T HTC One M9 running Android 7.  I cannot start the personal Hotspot.  Has anyone able to use the Hotspot that is build in?  I have the hotspot service on my account.

     

    Everything else worked fine (i.e., 4G LTE, MMS, etc).   This is the only problem.
