September 05, 2026 speed sucks
Bruce
Fidium Fiber
August 10, 2026 While speeds are ok, they lure you in with the promise of low rates, and jack up the price over time. Getting to actual customer service is difficult. I have lost access to my email multiple times, the last time was for over a week. This is unacceptable. It was nothing I did, but something they did in their backend. No notification, just loss of email access. Have a ticket, but I'll be lucky if they call back within 24 hours. Last time, I had to hound them multiple times, including getting in contact with the state PUC to find someone higher up to speak with. Losing access to your bills and attorney's is not cool. Cannot recommend them and their lackadaisical attitude towards service.

July 11, 2026 it's NOT 1 gig, actually more like .5G. About the same as Xfinity's 500MbPs at the same price without the streaming privileges.

Fidium Fiber
February 18, 2026 They did do a wonderful job making sure that some damage during installation was covered when I had to get it fixed (accidentally drilled a hole through my power cable coming from the street). The technician was very professional and apologetic, and also personable to talk to. He didn't get defensive or try to wave it away; he knew it was severe damage and immediately got in touch with his boss. The process was relatively easy, I had the electrician who came later call them for the invoice. That alone is excellent customer service, and I can forgive a lot of other minor nonsense if they can be that honest with me. The only snag I've had since then is their app is a bit of a pain to use sometimes, having difficulty connecting to my network with it.

XFINITY Cable
February 12, 2026 The price is ridiculous for the speed provided based on what people in different countries are able to get. Download speed is adequate at best. Upload speeds are terrible. It really should be better. The best thing I can say is I don't have outages. So it pretty much is always available, so that's good.
