AT&T Customers Surprised by 'Unlimited Data' Limit

AT&T has some 17 million customers with "unlimited data" plans that can be subject to throttling, or the placement of virtual wheel clamps that slow download speed dramatically. What's surprising customers is how little data use it takes to reach that level -- sometimes less than AT&T gives people on its "limited" plans.

Say Goodbye to Unlimited Data Plans

Come October, customers among the top 5% of AT&T's data users in any given billing period will be subjected to reduced access speeds. Rival Verizon introduced a similar policy earlier this year. With the smartphone market all but locked up between these two players -- and AT&T moving to acquire T-Mobile -- this is an ominous development indeed.
