AT&T Adds DataConnect Overage Charges, Pulls Plug on Unlimited Pre-Paid Data PlansSShockingly, AT&T has discovered that *gasp* people are abusing their unlimited pre-paid data service by tapping into it with their laptops. As a result, the plug is being pulled on the $19.99/month option starting on November 12th. AT&T will also place a cap on the legitimate laptop DataConnect plan that works out to 5GB a month for $60. Overages will be billed at $0.00048 per kilobyte, which translates into a bank account-busting $480 per gigabyte. However, rumors claim that AT&T will terminate service once a $100 overage threshold has been reached. [PhoneNews via Engadget Mobile via MobileBurn]
