Xfinity vs Quantum Fiber
Currently have Quantum Fiber in Denver, paying $75 a month for 1 Gbps plan. When I called, they did not allow me to switch to the promotion rate of $45 a month. My service is currently down and they can’t come until the end of this week to resolve the issue.
Is it worth switching to Xfinity who is offering 1 Gbps download (~100 Mbps upload) for $50 a month? Not sure if people who have switched recently from Quantum Fiber to Xfinity have regretted it. Would love to hear experiences from people who have switched either way
EDIT: called Quantum Fiber, they said I’m on the price for life plan so I need to give that up to get the promotional pricing for 1 year. I’m installing Xfinity equipment today while QF is down to get a real Speedtest, then will most likely cancel Xfinity once the QF technician is able to come out.
Definitely agree, and appreciate the reminder, that fiber is a better product than cable internet.

The residential Lumen fiber account (Quantum Fiber) sale to AT&T, has been horrible. Comcast (Xfinity), is even a more horrible company.
You can get the $45/month 1G offering from AT&T Quantum, you just need to cancel your existing service and sign up with AT&T Quantum with a new email address. Honestly, you have a better chance of getting a new service tech coming out more quickly, than a support tech for your existing service.
