Where available, 5 GIG internet gives you approximately five times the speed of Internet 1000. This additional speed may enhance your ability to stream 4K videos, stream in 1080p, and download large files all at the same time, on even more devices at once. Because AT&T offers fast upload speeds as well as download speeds, influencers and video creators can also expect dramatically faster upload times for large video files.
