I would never recommend Frontier! The internet service is awful and when I spoke to the customer service, the guy told me he even has Spectrum instead of Frontier. I’ll be switching to Spectrum.
Our installation tech was fantastic!!! He helped me set the app up on my phone and showed me how to navigate everything. He was professional, kind, personable and polite. He made me a happy customer, and I hadn't even tried out the internet yet! I remain very impressed.
