AT&T broadband users will soon face a cap on the amount of internet data they can download a month, Wired reports. Traditional DSL users will be capped at 150 GB per month, while subscribers to the fiber-backed UVerse system have a 250-GB limit. Usage over that will be charged at $10/month for 50 GB, the company says. The company says that currently only a small percentage of users — around 2 percent — use this much data a month. If that’s the case, it’s not clear why the company is bothering to install the caps. It is, however, the same rationale (and the same usage stat) that the company relied upon to explain why it would be capping iPhone data plans last summer, which had hitherto been “unlimited.”
