XFINITY Fiber
December 29, 2025 I have been very disappointed with Xfinity, especially of late. For the last several weeks, we keep losing coverage. Today, we were without internet access for over 4 hours. My husband works from home so it is especially problematic. It takes forever to reach a live person at Xfinity so we are left with an automated announcement of estimated recovery time. It is beyond annoying and is having us seriously consider other providers.

December 13, 2025 My provider has lower sppeed options but they dont promote them. When I asked for lower, I was Told that wasn't advised. I told the agent that I wanted to try it anyway. It was nearly impossible To get my speed lowered with a lower price until I hung up and called and talked to someone higher up. It was no problem and I have no problem with the lower speed and the price is much better. Now they're offering small mobile Service with the smaller package being only $12 a month. Also one line free for one year! I just signed up But not started the plan yet.

Verizon Fiber
December 08, 2025 I have very quick internet speed and it works in most areas. I don't like that sometimes it cuts out when I'm far away from big cities and in very rural areas, even when other people's phone service is still working. My phone has great service most of the time, but it switches between LTE and 5G often, which sometimes affects the speed of my phone.
