What Our Customers Say
“It’s been over a month since we got signed up with Open Fiber and I’ve been pretty pleased so far. The bill is a good amount less than what we were paying Comcast each month and for the first time I can have video calls with work from home without any connection problem.” – Megan L
“Even with a bundled promo rate for ATT, Atherton Fiber with Paxio 250Mbps service will save me $40/month since I was frequently getting overage charges due to 4K streaming TV.
Getting Atherton Fiber installed (in my case with Paxio) was a painless and fast process. No install charges and now I have a dedicated fiber line and don’t need to worry what games the big companies might play in the future.” – Vance B
“I signed up last month. So far, Atherton Fiber / Open Fiber has been fast and reliable. Installation and setup was free. I now have a faster speed at less cost than my previous ISP.” – Alex K
