October 31, 2026 CUSTOMER SERVICE...? On hold for 30 mins and get 1 person. Placed on hold to transfer, another 30 mins and I hung up. WORTHLESS!!!
Mary Ann M.
Inland Cellular
October 14, 2026 I have ICell Service poles on my property, and do not pay for Cell or Internet Service... I do not use it for TV, I have DISH, for that. Sometimes it is pretty good, most of the time it is very sporatic, cuts me off during phone conversations, quite often. Cannot get on or stay on internet, very slow a lot of the time. I do not use it for TV or gaming, most of mine is research, business calls, documents that need to be sent. Often who I send e-mails to, they do not receive them or receive them days later. Download this am 56.7 Mbps & Upload 4.6 Mbps

Fybercom Fixed Wireless
July 11, 2026 This used to be a good company. Started to have buffering issues on all devices. Took 10 days to get a tech out. Installed new modems. Problem still there. Call tech support who indicated it is a problem with one of their towers and that it affects numerous customers. Asked if the Engineers communicate with tech support and apparently they do not. They want me to change to fyber and asked why they don't communicate with the affected customers who are waiting for issue in the tower to be corrected, especially if they can identify each customer that it is affecting. The time it takes to get a service tech in to change the modem, rather than being honest that something else exists is not a good model plan to show support for the customers. Being down without your internet which supplies TVS, Security Systems and other devices while still paying the bill is highway robbery especially at the prices we are being charged.

Quantum Fiber
May 14, 2026 I have overall been very happy with our internet service as far as speed and pricing. Unfortunately, customer service does seem to be lacking. In the past when we’ve had issues with our internet service, we haven’t been able to get ahold of someone for hours, and when we can, they’re not able to help. But me and my spouse both work from home, and the speed and capabilities of fiber have been really good. It can keep up with all of our devices really well.
