Provider details verified: Our take
CenturyLink's Quantum Fiber is refreshingly simple — flat pricing, no contract, no caps where fiber is available. Outside fiber areas you're on aging DSL, so availability is everything.
Choose CenturyLink Fiber if…
- Your address is on Quantum Fiber — flat, simple pricing.
- You want no contracts and no data caps.
Skip it if…
- Your address only qualifies for CenturyLink's older DSL.
Pros
- Flat pricing — One rate with no promo unwind on Quantum Fiber.
- No contract, no caps — Cancel anytime with unlimited data.
Cons
- Aging DSL outside fiber areas — Non-fiber addresses get much slower service.
