Frequently asked questions

Is Frontier's price really flat?
Yes, no promo cliff, no contract, no equipment fee. The $45/500 and $70/Gig quotes are what you pay month 1, month 13, and month 36.
Why is AT&T Fiber more expensive?
Mostly brand pricing, AT&T can charge a premium because of the bundle ecosystem and larger installed base. Performance is essentially identical.
Do either of them have data caps?
Neither. No caps, no throttling, no contract. This is how fiber should work.
