Got mine going by calling the 800 number in this post. Only took 1 minute to get connected to a nice woman in Florida. She said it failed activation (duh) and maybe in part because my data plan would not upgrade to LTE. I was on the 4GB enterprise with tethering. She said it would not let her change it either since they dont sell it anymore. My other line with the 2GB plan upgraded just fine. She offered to put me on 3gb but I would loose tethering or the 5gb thats $5 more. Guess its ATT way of pushing out the old plans.....I thought she was going to push the data share plan that is even more $$$ ANyway my phones working so I really dont care right now. Thanks for posting the 800# I could never get through on the regular number. The girl said they had 1800 calls in their queue at one point tonight.
