Customer Reviews for Internet Service Providers in Missouri
Customer Reviews
Roger S
Starlink Satellite
November 03, 2026 The speed should be 300 Mbps. What I don't like is the price increase, it was $85.00 month, last month $130.00 month, just received a email saying that next month will be &143.00. Customer support is AI and does not help.
Ann N
Spectrum
October 23, 2026 Our area has experienced at least two outages lasting several hours within the past month, and yet my bill went up $10. (Now : $110.00 a month for internet, one cell phone usage, and one fixed home phone.) Calls often drop and internet service drags at different times of the day. I’m certainly not satisfied paying so much for intermittent service.

i3 Broadband Fiber
October 09, 2026 I am actually with Circle Fiber that got bought by i3 Broadband that got bought by T-Mobile Fiber. it's 2026, and they still do not have dual stack IPv4/v6; which I have filed FCC complaint about. Support sucks, and constantly small outages.

NEMR Fiber
September 29, 2026 I love our Cooperative! We get money back every November. They have the best customer service and truly treat us like family.

NEMR Fiber
September 29, 2026 We have been with NEMR for years. Great company. Very consistent internet. If we have any problems (usually our fault) a tech is at our house the same day!
