Stream Saver: Stream Saver allows you to save data on content it recognizes as video by streaming higher definition video at Standard Definition quality on compatible devices (unless the video provider has opted out). AT&T will activate the feature for you. Check your account online to see if the feature is active. Once active you can turn it off or back on at any time online. Stream Saver will not recognize all video content. Ability to stream and video resolution may vary, and be affected by other factors. Restrictions apply. See att.com/streamsaver for more details.
