Customer Reviews for Internet Service Providers in Arizona
Customer Reviews
An Arizona Customer
CenturyLink DSL
January 28, 2026 My provider is Centurylink, and I am located in Arizona. Centurylink does the absolute bare minimum to expand their footprint, and they also do not upgrade their current infrastructure. They have not upgraded the speed in my area in over ten years, yet their prices increase every two to three years. They have a monopoly on the service in my area, and they use that to their benefit by pinching pennies and sitting around as they generate revenue. I don't understand why they have no competition, especially because my city is growing so fast.
An Arizona Customer
CenturyLink DSL
January 23, 2026 Century Link customer service is terrible. They seem to use an offshore call center that never knows what is going on locally and why service is down or faulty. Speeds are quite slow comparative to other companies, but we are used to it now.

Cox Cable
April 18, 2023 I actually have nothing bad to say about Cox so far. The price is very reasonable for those on a budget. The service day to day is pretty much always good, always the same. Sometimes when it storms it can run alittle slow, but that's to be expected. All around, it's great swrvice.

Cox Cable
February 28, 2023 Cox keeps raising their prices but the service gets worse and worse. Some days I have extremely slow upload and download speeds. Resetting the router usually does not help. I wish that I could get a different internet provider; but Cox is the only company that provides service in my area.
Tanya O
Cox Cable
February 25, 2023 I have very good service where I am. I know some of my neighbors complain about service interruptions but for me it's very rare. The few times I have had to call customer service, the representatives have been very nice and helpful. I've never had billing issues but I did have one modem stop working after several years. And a few years ago I upgraded to the modem and that was also very simple - I think in that instance I was able to request the new one by mail, and mailed the old one in. I've never had a billing issue so I can't comment on how they handle that, but I've no reason to think it would be any less smooth than other customer service encounters I've had.
