In October of last year, the FTC filed a complaint and sued AT&T for imposing unfair data throttling on grandfathered unlimited data customers after they reached 5GB of data usage. Obviously, unlimited data isn't truly "unlimited" if it's only useful within the first 5GB bracket and then slowed to a nearly unusable crawl after that.
AT&T has finally taken action against the throttling. Under one of the cellular carrier's policies, an updated paragraph notes that AT&T customers on the grandfathered unlimited data plan that had experienced slower speeds after 3-5GB of data usage will have their speeds restored at the start of the next billing cycle and that reduced speeds will only occur in congested areas to help with data flow for everybody else:
