August 15, 2026 Internet provider SUCKS. Had for 2 years, I could count on one hand how many days the internet was working properly. I mean this with my whole heart, DO NOT BUY FROM THEM, YOU WILL REGRET EVERY SINGLE DAY OF IT. Not to mention that when the employees come out and try and "fix something" it somehow always gets worse. Not a joke, worse provider Ive EVER had this many issues with, and Ive been through like 12 different ones. Do not buy.

April 13, 2026 T-Mobile's internet pricing is the best value. The box acts like a hot spot so we can take it with us when we are on vacation. We vacation in Europe and T-Mobile gives us 5G extra for each European country that we visit. It is great when we are traveling by car and using Google maps for directions.

i3 Broadband Fiber
February 27, 2026 We took a risk with I3 when they came to town. Initially, we didn't have fiber and none was being offered around us. All we knew was that our current provider had consistent outages and we work from home, so we needed a change. I3 came out and installed the fiber first. The installation was seamless and took about an hour. Since it has been installed (about 1 year now), we haven't had a single outage or a need to call I3 to come out.

December 29, 2025 My internet provider was wonderful at first . They came to my house , had to dig through my yard. Cleaned up really well. For the first six months speeds were great . After that , everything loads slowly. We have a deal for our internet so we pay a great price , but I’ve had them hard reset it multiple times . It’s good for a few days then back to bad !
