The introduction of fiber optic internet in our lives has made a lot of things much easier than before. This is especially the case for streamers, gamers, and other thousands, maybe millions, of people who rely on the internet excessively. Fiber internet is now the choice and preference of serious internet users due to its remarkable bandwidth, ultra-fast speeds, and little to no lag.

Until more recently, all these advantages used to have a dear price to pay. But that is changing. And you can now get a Fiber connection at rates competitive with high-speed Fiber-powered Cable broadband. That said, the only downside of fiber internet is limited availability.

Quantum Fiber, formerly known as CenturyLink Fiber, is one of the best fiber internet providers in the United States. The service is delivered over an advanced Fiber network, and reaches your home via fiber-optic cables entirely―which is why the connection you get is 100% pure fiber.

In this article, we talk about Quantum Fiber internet, availability, and offers. And we hope as we conclude, you’ll find yourself more informed about the value of a subscription to Quantum Fiber.

CenturyLink and Quantum Fiber are both a part of Lumen Technologies – dedicated to empowering people’s digital lives with the best in internet technologies. Lumen used to market its high-speed DSL and fiber service under the CenturyLink brand name, but its fiber internet services will now be marketed as Quantum Fiber—currently available in 14 out of 16 CenturyLink coverage states.

This transformation moves up the existing and potential customers of CenturyLink fiber to a premier service experience over a highly trusted fiber network. Here’s a sneak-peak into what Quantum Fiber has in store for you:

  • Reliable Fiber Customer Service Team is available 24/7 to give you just what you need, when you are in need 
  • No annual contracts and unlimited data
  • Prepaid internet service that saves you the hassle of recollecting credit checks and bills
  • Multiple payment options, including PayPal, credit cards, and Apple Pay
  • An ingenious app that brings everything together at your disposal for complete control with easy functionality

Quantum Fiber Availability

The good news is Quantum Fiber is available in more states than many other providers' fiber plans, and you'll find it hard to find better rates. According to a Lumen spokesperson, the company is investing in expanding its fiber footprint and will continue to expand Quantum Fiber internet to new markets throughout 2023.

Quantum Fiber: Plans & Prices

To be honest, if you are in a location where Quantum Fiber is accessible, it is a no-brainer choice. Instead of complicating things with multiple tiers and prices, Quantum Fiber keeps it simple with two plans. Their fiber gigabit plan brings you up to 940 Mbps internet speed for $70/mo. This is perfect if yours is a household of power users and multiple internet-connected devices. To give you a comparison, this plan offers up to 20x faster upload speeds than a regular cable internet connection. This means you can seamlessly share 4K videos, and play to win every battle, and essentially rule the digital space with a fast-speed internet connection by your side.

If you want to enjoy the reliability and fast speeds of a fiber connection but have moderate internet usage, you would enjoy their other fiber plan more. With this plan, you get up to 200 Mbps of internet speed for $30/mo. This is great for small to medium households. You get the same symmetric speeds, and virtually unlimited internet without having to pay for internet speed you won’t use.

Quantum Fiber does not make its best price offer conditional with bundling, as quite a few ISPs do. Instead, you are given the best price on the internet-only plan. You do not have to pay for a service you do not need just to get a discount.
