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).
