Customer Reviews for Internet Service Providers in California
Customer Reviews
A San Leandro, CA Customer
XFINITY Cable
April 25, 2026 I'm very happy with the speed of my internet it's fast and reliable. I rarely experience outages which is also great. However I have noticed the price has gone up over the years and it's getting a bit expensive. I have been with Xfinity for over 10 years so I think it would be nice if they offered some kind of loyalty credit or discount to long term customers. Overall the service is solid but the cost could be more affordable.

Sonic Fiber
January 03, 2026 We hope Sonic can be an option in more areas to get rid of the menace that is Comcast and AT&T with their higher prices and worse service.
Vin N.
XFINITY Cable
October 22, 2023 Xfinity’s speed is the best and our home internet is always fast no issues! The times we were having issues their customer service was great. I loved that the chat was available with a live representative. They walked me through every step and did all they could to help me.
Don R
XFINITY Cable
April 12, 2023 I've had Xfinity internet for over 6 years and I have no intentions to switch to a new provider any time soon. I do not have cable television so I stream media hours a day via an Amazon firestick and my internet connection never lags. The price isn't the best but I feel like I get my moneys worth considering I use the internet more often than most people and I never have a disruption in speed.

AT&T Fiber
March 31, 2023 I appreciate installation was free. Internet is consistently fast. I can only remember one short outage in the past two years. The provided all in one modem is able to keep up with 12+ devices connected to it.
