Techgage reports AT&T has implemented data caps, you can read it over here.
Beginning today, AT&T will be implementing a monthly data cap plan for its DSL and U-verse customers. AT&T DSL customers will have a 150GB per month limit, while U-verse customers receive a slightly roomier 250GB monthly cap. Subscribers that exceed these limits will be charged $10 per each additional 50GB over the limit.
This decision very well could mark a turning point in history, and likely will encourage other major Internet Service Providers to join in. To put that in perspective, Comcast has roughly 16 million Internet subscribers, and AT&T’s recent plans will easily double that to north of 32 million U.S broadband customers that are now subject to data caps.
