Spectrum Cable
July 23, 2025 We have had Spectrum at our house for about 4 years now and we haven't had any issues so far. We have the lower plan with slower internet speed, but it is still quick and works well for us. The pricing for internet alone increased a lot after the first year, which we weren't too happy about. However, we recently just switched to Spectrum mobile because they were offering a great deal for 2 years for internet and mobile.

Hawaiian Telcom Fiber
November 19, 2023 Hawaii Telecom recently installed fiber optic capability on Kauai. At that time, they offered 6 months free. We are seniors on a fixed income. It sounded too good to be true, but we signed up anyway. We have been extremely pleased with HawaiiTel. Their promises of high speed and quality have definitely been true. After the free 6 months, our cost will be only $15/month, which is considerably better than our previous provider. We have told anyone who had asked how pleased we are. Hurrah, HawaiiTel!
PS
Spectrum Cable
June 04, 2023 My internet provider is Spectrum. The area I live in doesn't have many internet options so everyone is basically forced to subscribe to this plan. Luckily, I am happy with the speeds and seem to have a nicer connection than other people around the US. I'm really disappointed because my bill went from $50 to $80 in less than two years. It did go up a little since my introduction price was a limited offer, but then after that, they rose it a little again without notifying anyone (this is for all Spectrum customers nationally). I also think it's ridiculous the amount of paper waste they send to my house trying to get me to sign up for additional services.
