Why Fiber Wins
Future-Proof Technology
Fiber's infrastructure can support faster speeds as technology improves. Cable and DSL have physical limits that prevent meaningful upgrades.
Consistent Performance
Unlike cable (which slows down during peak hours) and DSL (which degrades with distance), fiber delivers consistent speeds 24/7.
No Hidden Costs
Frontier Fiber has no data caps, overage charges, or equipment rental fees (equipment is included). Cable often charges extra for everything.

Frequently Asked Questions
▶▼Can I upgrade from cable or DSL to fiber later?
Yes. If Frontier Fiber isn't available in your area yet, you can check back or sign up for notifications. When fiber becomes available, you can switch to get significantly faster speeds with no equipment costs.
▶▼Will fiber internet work during power outages?
No. Fiber requires power to operate, like cable and DSL. During outages, you'll need a cellular hotspot or mobile backup internet. Our fiber service is more reliable during normal conditions with 99.9% uptime.
▶▼Is fiber internet safe?
Yes, fiber is secure. Light signals are immune to electromagnetic interference unlike copper cables. Frontier Fiber includes free security features and advanced encryption.
