May 20, 2025 Fiber Customer here. - Since moving in the area, my wife and I work in public sector from home, require reliable internet, and was looking for a top tier Internet Service Provider in our area. CassComm provided that and more. We've had then for a few years now, and their services are everything we asked for; reliable, fast, affordable, consistent, quick and professional customer service. They are always ready to answer phones to resolve any billing/service issues, and answer questions on their social media. Their field techs/linemen are some of the toughest and most skilled in the state, and respond just as fast if not faster than our electric providers during power outages regardless of the harsh weather conditions. Our family has had them for a couple years now and plan on growing with them during our time here. Thanks Casscomm! You all are really great.

November 24, 2024 For the area where we live, it's ok. I feel like they get faster service and then it gradually slows down over time. I don't think they keep up on increasing their speeds to compete with other companies very well.

April 19, 2023 Our internet provider is usually dependable, but will sometimes just crash for awhile. The entire neighborhood will go down. The pricing is expensive, but I suppose no more expensive than other providers in the area. They do give us HBOMax for free, though, which is a nice perk.
