Recently, it was announced by AT&T that they would introduce data caps for its internet customers.
The company plans to begin capping users of its slowest at 768 kilobits per second DSL service at 20Gb per month. As the speed of the plan increases up to 150 gigabytes per month at the 10 megabits-per-second level, the limit would increase too.
In an FCC filing, the company said, "AT&T plans to initiate a broadband Internet access usage trial in Reno, Nevada beginning in November."
