Fantastic team and great coverage

AT&T Internet

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.

Great experience!

The service was outstanding. I called on Sunday and they put me on a schedule for Wednesday. The technician came on time with all protective gear: mask, shoe cover. He was very professional, promptly explained everything that I did not have a question to ask. We have our hi-speed internet in 1 hour. This is great teamwork. Thank you and your customer service team.

We switched to CenturyLink and could not be happier. It is so much faster, has never cut out and had the best installation customer service. The price is also great.
