Customer Reviews for Internet Service Providers in Montana
Customer Reviews
A Kalispell, MT Customer
Spectrum Cable
March 22, 2026 We currently have 500MB+ speed service with phone as well from Spectrum. They are currently charging around 110 a month which is reasonable for service. We started about 8 years ago and had to have crews install in our area so we could get off Centurylink. I have had consistent service with them and have had no problems. I'd give them a 9/10.
A Lame Deer, MT Customer
Range DSL
February 09, 2026 I have quite a few internet providers, not to mention helped a few as well. I have not seen a internet provider not allow access to the modems that they provide, with the default settings that are set overlap neighbors wifi and make service almost impossible to use.as well as during installation put a router and modem on a microwave and except it not to fry the router. Then blame the client for destroying the router minutes after installing it. I get that there service is limited in certain areas.

3 Rivers Fiber
October 24, 2025 3 Rivers Communication is the only option in my rural community. With that, they can set prices as they see fit without having to worry about competition. While I currently view the price as fair for the speeds offered, I do with prices were more affordable. One benefit is that taxes and fees are included with the price, so the listed price you see on their site is their rate.

Spectrum Cable
September 28, 2025 Spectrum provides reliable internet service in the 59102 area. Speeds are generally good for streaming, remote work, and everyday use. While pricing isn’t the lowest, it’s reasonable considering the service quality. Customer service could be better, but installation was smooth and outages are rare.
Hannah S
Access Montana Fixed Wireless
June 27, 2025 I have been fairly happy with my internet provider. The installation was fairly fast and done well and they were very informative while setting everything up. The price of our internet service isn't my favorite being close to $60/ month, but I know there are others who pay higher amounts so it's something I have to accept. But I really do enjoy my internet providers customer service. We had an issue with our internet not working over the summer and they worked diligently with us to get it back working as soon as possible, even having a service tech come re-run new cable on a weekend for us. We were so thankful. And we rarely do have issues, so overall Access Montana has been a great provider for us.
