AT&T began data capping its U-Verse broadband customers back in 2011, although it didn't enforce its new rules. That changes this week as May 23 has arrived: the date the company said it would begin enforcing caps.
Whereas the cap was 250GB per month in 2011, that's been increased to 300GB for those with 768 Kbps-6Mbps plans; 12Mbps-75Mbps plans will have a 600GB cap, and 100 Mbps-1Gbps means a 1TB cap. Should you exceed the limit (and you'll receive plenty of e-mail warnings before you do), you'll be charged $10 for each 50GB of extra data. Alternately, you can pay a flat $30 extra per month for unlimited data.
AT&T says about 4% of its customers go over the new limits.
DSLReports cites the move as a "fairly obvious effort by AT&T to try and stop cord cutters from defecting to streaming video options", and wonders whether the company's upcoming streaming video service will be exempt from the caps.
