Fantastic team and great coverage

on September 28, 2019

Absolutely fantastic! Tech came out to help install and, due to the wiring in our apt, it took a while to find the correct outlets. But he was so patient and helpful and kind, really going above and beyond to make sure things got set up so I could have the level of coverage needed to qualify for work from home. Truly amazing guy, I honestly can't speak highly enough of him. He kept trying long after I suspect most would have given up. Huge THANK YOU to AT&T for the coverage at the right price (literally half the price of the competitor in this area), and more importantly for having such an amazing guy on your team. Thank you.

Best coverage

on May 19, 2021

I travel often and I definitely travel around upstate New York and everywhere I go AT&T is faster and even seems to have more coverage than the others, so I am not sure who is doing the tests, but everywhere I have been, AT&T seems to outperform (also I don’t like AT&T as a company, so trust my honest review here).

Stellar customer service

on October 15, 2020

The difference between Mediacom and AT&T is that Mediacom cares. I have used both services and the difference is vast. After a recent hurricane in my area, Mediacom went above and beyond to ensure that I was up and running again. There was an unknown problem with the equipment on the pole at my house, and they had it fixed within an hour of my request. They legit care, and that goes a long way!

Terrible Service

on January 24, 2021

I have had the hardest time with this company. Numerous times I was supposed to have been "locked" into a certain price for my bill and it constantly changes and goes up. If I have been "locked in" at a price it stays that way for maybe a month. I do not even get all my channels due to the Tegna dispute. It is very unfortunate there are no other cable providers in my area.
