Customer Reviews for Internet Service Providers in California
Customer Reviews
Monica C
XFINITY Cable
April 18, 2026 Xfinity is okay. There really are not a lot of options to choose from. Xfinity is good becasue they have actual stores you can go into and talk to customer service or exchange stuff. Previously when we had ATT we had to mail stuff back and wait. Xfinity still kinda sucks when you have to call, because it's clear I'm speaking with someone in another country, but they all do this now so as a consumer I generally feel screwed.

XFINITY Fiber
August 01, 2025 My connection is phenomenal. It never lags and never gives up, and the price is very fair for what I get. I enjoy the stability, especially considering I am a remote worker. The support is also very helpful.

Astound Broadband Cable
January 25, 2024 Initial prices are very reasonable compared to other providers, however prices have consistently increased over the years as a loyal customer. With cable, upload speeds are very slow compared to download speeds, which can be limiting at times. Initial installation was very smooth and they made it easy to bring my own equipment. Customer service and tech support has been very responsive and friendly in my experience.
