T-Mobile Home Internet Fixed Wireless
May 12, 2026 I am finding it more and more difficult to justify the cost of high speed internet due to the ever rising cost. I have an unlimited data plan thru my employer and I feel like I can just use my phone's hotspot for my needs.

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.

August 22, 2024 I live in a suburb of Charleston, SC. As a lifelong competitive esports gamer, internet consistency and speed was a major factor in choosing my ISP. Unfortunately, there were no big brand ISPs available in my area (Google Fiber, Verizon Fios, etc) and I was relegated to either Spectrum cable, or a company I never heard of called Home Telecom. Although unknown, they ran fiber lines so I went with them rather than Spectrum. Because
Of the lack of options, prices are inflated and we are taken advantage of. Speed is ok, I have little down time, but at 100 a month I’d expect a faster connection with lower latency.

September 26, 2023 We only have one option for internet in our neighborhood, therefore they put little effort into service. The price keeps climbing every year. We have internet outages regularly. It is in a new construction neighborhood so they have a monopoly.
