Good pointer. It lead me to a phonenumber to call and a real person who said she could help set up my personal hot spot. After that things too a turn for the worse. She could not set up the hot spot without cancelling my grandfathered unlimited data plan. She said I had to cancel that and buy a $50/mo 5Gig plan. I told her that is not what the AT&T wireless iPad support web site said. She wouldn't budge and I wouldn't cave in and accept a new plan - so - I did not get a hot spot, but I get to keep my unlimited $30/mo data plan.
End of discussion for now. I'm going to try to find a basis for an appeal. Wish me luck. If I succeed, I'll post here. If not, thanks to the members of this support community for your assistance.
