January 06, 2025 We're overall happy with Home Telecom. It was really the only choice at the time we decided to move to this area, and there have since been other options but we've stuck with them. The speeds do have issues occasionally, but customer service is good and pricing is fair so we really have no reason to switch.

November 23, 2024 I have had HomeTelecom for about 6 years now and overall am very happy with them. Initially I was put off because the box they had to bury in our front yard prevented grass from growing there, in fact even now it's still a bald patch. However the service itself is great. Fast speeds and has been pretty solid in terms of reliability. I just wish the pricing was a bit better. It is inline with competition overall but paying over $150 a month for 1Gig just feels like a lot. I currently subscribe to the 300mbps for about half that and honestly it's more than I need. So while I have a few grumbles, I still highly recommend them.

September 22, 2024 I like how fast that the download speeds are when I want to install software on my laptop and for the price it's one of the best that you can get for now. My family has had this service provider since I was in elementary school and with the growth going on in the Charleston metro area these days it's still maintains the high speeds. Now there was moments where my family couldn't use the internet for several hours but those were isolated to certain locations in their services and have only happened a handful of times per year outside of high wind events or landfalling tropical systems. Overall as new internet service providers work their way up to my area, I'll still stick with them until I have to make a change due to a price increase that I couldn't budget for. That's unlikely to happen for now though.
