AT&T today reacted to customer dissatisfaction regarding its network management and data usage policies by changing the threshold at which it will throttle customers. Last year, AT&T said that it would throttle the data of its heaviest 5% of users. The amount of monthly data consumed by those users is approximately 2GB. Customers who have unlimited data plans were seeing their data speeds throttled once they reached that threshold. Now, AT&T said it will not throttle the data of its 3G unlimited data plan customers until they reach 3GB of data usage in one billing cycle. They will be warned when they approach the limit, and throttled for the remainder of the billing cycle if they exceed it. The next time customers exceed 3GB in a month, their speeds will be reduced without a text message warning. For customers with LTE 4G phones, the throttling threshold is 5GB, and the same terms apply.
