A new report on Sunday states AT&T will soon introduce data caps to its wireline broadband subscribers nationwide. AT&T has confirmed the move, which will go into effect on May 2nd. The caps will be set at 150GB per month for DSL customers and 250GB for U-Verse subscribers. AT&T will charge $10 for every 50GB over the cap, though overages will not be charged until customers exceed the cap in three separate months over the life of an account. The carrier states that only 2% of DSL subscribers will be affected by the change, though it does not specify what percentage of its U-Verse subscribers might be affected. AT&T also confirmed that it will implement a notification system that will “proactively notify customers when they exceed 65%, 90% and 100% of the monthly usage allowance.”
