Tried to activate online, first one asked for my Onstar car number, I told her she was not in the right connected car plan, got transferred several times, finally got to the right person but she could not verify me since I didn't have my drivers license number handy. After a total of 57 minutes on the phone, she assigned a cell phone number and a eighteen digit case number and said go to the AT&T store.
Took the eBay/Besy Buy Mobley to the AT&T store in Stillwater yesterday. Megan met us at the door, sat down at a table and in about 15 minutes had it activated. She said I might get Billing to wave the $25 activation fee. Total monthly bill will be $25.94 with all of the extra fees.
Got home, plugged it in to the power supply, It works!
Got a weak signal of -115 dBm, 130 kbps down, 10kbps up.
Speed increased when moved to a stronger signal, this is -106 dBm:

And -100 dBm:

Kinda slow, but faster than Hughes Net in the evening hours.
Still have a lot of places to try for a stronger signal.
