Not what I expected

Matt on December 30, 2019

Calls drop a ton, I can't use the internet if I'm on the phone, and the speed isn't as fast as I expected either. The main thing is not being able to use the internet while on the phone.

Blazing Fast Internet and The Best Customer Service

Ml Bell on August 05, 2019

I've had service for about 6 months now, and it has been exactly as advertised. Super fast speeds and low latency. I've only had one issue so far, fiber got disconnected across the street and they had a tech out to my house in 45 minutes. He quickly fixed the issue and I haven't had any other service interruptions since. Can't recommend enough.
