AT&T is perhaps THE absolutely worst internet service provider I've ever used in the last 20 years. I started using them back in 2005, as I lived in a very old apartment complex, they only had DSL service at the time. Each year that had gone by, I was told they'd start running fibers into my neighborhood. Well, it went from 3, to 5, to 10 years and my prices had gone from an introductory price of $14.99 all the way to $48 and I was getting a mere 3-5Mbps download speed and ~0.5Mbps upload speed. A full DECADE later, they still didn't have anything faster and the prices kept skyrocketing each year. FINALLY, I had enough and switch to Xfinity for about the same price and 10+ times the download speed. AT&T, as a whole, the speeds were old and out-of-date (at least for my area), prices were expensive, and the customer service was horrible,

I've had several internet providers over the year, and I am pretty satisfied with the service. I would obviously always want an internet that is even faster and while I do believe such a service is possible, this current one is still satisfactory. I am able to have as many as ten tabs loading at once without the browser crashing, which is useful and convenient. This internet disconnects rather rarely and when it does it does not stay that way for a very long time. Overall, I am satisfied with AT&T Uverse, but am interested in a provider with faster speed.
