I have had the original at&t unlimited data plan for the iipad since the very first ipad back in 2010. I dont think at&t or anyone knew how popular they would be. At&t stopped the unlimited data plan for the ipad 3 months later. From what i understand, they didn’t think ahead. The legal jargon in the original agreement didnt protect the company to raise the price. You think they would have raised it by now? Of course they would have. Its been 9 years! They did find a loop hole tho...they were able to throttle those using too much data on their grandfathered unlimited plans. Given the choice btwn throttling and raising prices...they would have raised the price if they could. They couldnt.
