Customer Reviews for Internet Service Providers in Maine
Customer Reviews
Barbara J.
Fidium Fiber
September 16, 2026 Service is okay. Fidium customer service is abominable. They told me when I signed up that at the year mark, I could call and keep the same pricing - $67.50 per month. I called, they said it was granted, then they proceeded to bill me $87.50 for the next six months. I called every month, until I finally gave up, paid them the $87.50 and then my bill went to $90. I called to terminate their service in per disgust for this company (to Spectrum for better service, $15 lower a month plus streaming of certain channels). They said I would get a sticker in the mail to return their box - that it would arrive in 5 - 7 days. I got their bill - they charged me for THE FULL MONTH, they did not prorate the bill from the stop date. I called twice - one customer service person said it would be prorated, the second said it would not, the supervisor said that it would be. I am STILL waiting to get their return sticker in the mail. DO NOT sign up with this company - they WILL NOT deliver what they promise, then they put you through heck and high water to fix back to what they promised you originally. I am exceptionally glad to be rid of them!!!

Fidium Fiber
September 11, 2026 First. They lie about the promotional price. They claim $30. But bill you $50. Their internet drops off and on. up to 40 minutes. Tried calling them about the internet dropping. Called 4 times in the same day. First 2 times. Busy signal. 3rd time, Said call connecting. Nothing happened after that. 4th time. Phone just rang and rang and rang. Have had them for 2 or 3 months. Useless internet/Company.

Spectrum Cable
June 16, 2026 We have been using Spectrum Cable/Internet services for awhile now and are pleased with the variety of programming offered and internet speed. Customer service is reasonably good, and you can depend on quick response for outages. The one thing that is a downside is the price, it is more expensive than other providers in the area and they don't offer promotional offers to existing customers usually, but perhaps with a phone call to customer service they will give you a similar offer for loyalty if you don't switch. Fast internet speed, friendly reps with good service and reliable service make us continue to use Spectrum over others in the area, and we will continue as satisfied customers as long at the prices remain affordable.

GoNetspeed Fiber
May 24, 2026 I've been overall happy with GoNetspeed's fiber internet service. I was originally on an Affordable Connectivity Program plan through GoNetspeed. When the ACP ended, they let me keep the low-cost plan without trying to get me to switch to a more expensive plan. I have a faster and more consistent connection than I did with my previous cable ISP.
Dan H.
Spectrum Cable
March 21, 2026 I am paying $90/month for my internet service. Granted, it is fast. However, I remember when cable modems first came out and the service was $19.99. I do understand inflation, etc, but it's really tough to pay that bill every month. They never offer discounts or compensation when the service goes out, sometimes for several hours or a day. I just wish it were a little cheaper, that's all.
