Quantum Fiber vs. Fidium Fiber Internet Providers Compared

Quantum Fiber brings superior internet speeds and reliability at an appealing price

Quantum Fiber is a new, all-fiber brand owned by parent company Lumen Technologies. Lumen is the seventh-largest ISP in the U.S., based on its combined internet service of both all-fiber internet and DSL. In total, Lumen serves about 3 million customers [1]. Quantum Fiber is the all-fiber brand of Lumen. A second DSL-based brand also owned by Lumen is known as CenturyLink. We will review CenturyLink’s DSL service separately, as the two brands are very different in what they offer customers. Quantum Fiber is a very strong choice for internet service that earns good customer satisfaction ratings. If you sign up for Quantum Fiber, you’re going to get lightning-fast speeds and reliable service. Quantum Fiber offers clear, low pricing for gigabit fiber speeds that run up to 8000 Mbps. Fiber speeds will provide you with an internet connection that can handle any use you want from a home internet connection, including heavy streaming and gaming.

Great prices for Quantum Fiber plans up to 960 Mbps

Your prices will be good for Quantum Fiber. The first-tier price for all-fiber service will be $50/month for 500 Mbps. With any of the Quantum Fiber plans, you will get the use of a 360 Wi-Fi router for free. Quantum Fiber has no data caps and no required contracts. That means you won’t run into unexpected data overage charges or early termination fees. We like this simple, affordable pricing for fast fiber speeds. It's one of the best deals you’ll find on fiber internet.

Fidium Fiber’s pricing is simple, transparent, and matches other best deals.

Fidium Fiber offers competitive prices across the board, with no hidden fees. Understanding Fidium Fiber's pricing structure reveals significant advantages over traditional cable internet providers, who typically use promotional pricing that increases substantially after 12-24 months. The entry-level plan, currently starting at $30/month, offers 100 Mbps download and upload speeds. For families on tight budgets, this is one of the most affordable first-tier plan prices you'll find in the fiber industry. With those symmetrical speeds, you will get very good internet performance for activities like video conferencing. Higher-speed plans include 300 Mbps at $35/month, 1000 Mbps (1 Gig) at $55/month, and up to 2000 Mbps (for $75/month) available in some markets. These are fiber prices that can compete with any other fiber pricing in the nation. This pricing advantage exists because fiber-optic networks can scale bandwidth more efficiently than cable infrastructure, allowing providers to offer higher speeds at competitive prices. Best of all, you will get transparent, straightforward pricing from Fidium Fiber that is much easier to understand than the complex pricing of many other internet service providers (ISPs). Fidium Fiber requires no contracts, no bundling, and no data caps. That means you won't face bills with unexpected overage charges or early termination fees. This customer-friendly policy contrasts sharply with many traditional providers who lock customers into annual agreements with substantial penalty fees. You also won't have the usual $100 installation cost for new internet, as Fidium Fiber offers free professional installation. Fidium Fiber will include the use of a modem/router with your monthly plan price.

All-fiber internet from Quantum: the latest and greatest technology

Quantum Fiber uses the newest internet technology available. Their fiber-optic lines send data using light signals instead of electricity, and that’s why fiber is so much faster than any other kind of internet technology. An all-fiber connection will give you symmetrical speeds and enough bandwidth to handle any internet activities you choose. If you get a gigabit fiber plan, you can have up to 10 devices doing heavy streaming or real-time games online, and you will still have smooth performance. In some cases, though, Quantum Fiber advises that it may need to run Fiber-to-the-Curb (FTTC), with the last few feet of line to your house connected with coaxial cable. This is important, because even those few feet of coaxial cable will slow your upload speeds. Most of the time, that will not be the case, and you will get the all-fiber connection known as Fiber-to-the-Home (FTTH). But it is important to understand the difference in performance just in case you’re in that small minority that will get an FTTC fiber connection. Even an FTTC connection may still be the fastest internet in your area, though, and a Fiber-to-the-Home connection will definitely be your fastest choice.

Fidium Fiber brings the speed and reliability of fiber to new service areas.

Fidium Fiber offers symmetrical speeds ranging from 100 Mbps to 2000 Mbps, depending on your plan. That's great news if you live in a town that hasn't had fiber internet before. For example, fiber internet is often not available in rural states such as Maine and Vermont. However, Fidium Fiber continues to expand its fiber infrastructure in those states, adding more towns to its coverage area [2]. You can call our experts at 1-833-438-0953 to quickly discover if Fidium is available in your area. Fidium Fiber's symmetrical speed delivery represents a fundamental advantage over cable internet technology. The practical implications become apparent in real-world usage scenarios: home-based professionals uploading large files, families sharing content on social media, and households using cloud storage services experience dramatically improved performance with Fidium Fiber compared to cable alternatives. Network latency, a critical factor for gaming and video conferencing, benefits significantly from fiber-optic technology. Fidium Fiber connections typically deliver latency measurements under 10 milliseconds to nearby servers, compared to 15-30 milliseconds common with cable internet connections. This reduced latency creates noticeable improvements in online gaming responsiveness and video call quality. The dedicated nature of fiber connections provides another performance advantage. Cable internet systems share bandwidth among multiple households in a service area, potentially causing speed reductions during peak usage times. Fidium Fiber's infrastructure design maintains consistent speeds regardless of neighborhood usage patterns, ensuring reliable performance throughout the day. Peak hour performance stability makes Fidium Fiber particularly valuable for households with multiple users and devices. Some Fidium Fiber customers have said that they are not getting their promised speeds, but others report being very satisfied [7]. If you have any doubts, you can test your actual speed here to see what kind of performance your current internet connection is giving you.

Get free use of a  360 Wi-Fi mesh router or use your own router

If you order a fiber plan from Quantum Fiber, both your equipment and installation fee will be included free of extra charge. Keep in mind that equipment fees and prices do change with various promotions, so make sure you check with your customer support rep on current fees when you call. If you use the free router included with your Quantum Fiber plan, you will get their 360 Wi-Fi system. 360 Wi-Fi is a mesh network, which is much more sophisticated than a single modem/router [2]. You will be able to set up extra Wi-Fi Pods to ensure seamless coverage of your entire space, which is especially helpful if you live in a large home or one with thick walls. You will also have the option to use your own router. The only drawback is that Quantum Fiber tech support cannot give service or information for your personal router the way they can support their own equipment.

Free installation, free equipment loan with Fidium Fiber internet plans.

Several fiber ISPs will offer you good promotional prices and no contracts. They may even offer no data caps, as Fidium Fiber does. But very few ISPs also offer free installation for all their plans. The free installation for Fidium Fiber is a nice touch, meaning you don't have to invest upfront to get Fidium Fiber. Fidium Fiber's installation process demonstrates the company's commitment to professional service and customer convenience. The free professional installation (typically a $199 value) includes a comprehensive setup of fiber-optic infrastructure, extending from the street connection to a complete in-home network configuration. Professional technicians handle all aspects of the installation, including running fiber-optic cables to the optimal location within your home, installing the Optical Network Terminal (ONT) that converts light signals to electrical data, and configuring the Wi-Fi 6 Gateway for optimal coverage throughout your residence. Fidium Fiber will provide you with free use of a Wi-Fi 6 Gateway and a whole-home Attune Wi-Fi app, allowing you to control all your devices. The Wi-Fi 6 Gateway may have equipment rental fees depending on the plan (typically around $10/month for lower-tier plans, with some higher-speed plans including equipment at no additional cost). The gateway represents current-generation wireless technology that provides improved performance for homes with multiple connected devices, offering enhanced capacity for various connections, reduced latency, and better performance in environments with numerous smart home devices, tablets, smartphones, and computers. The Attune Wi-Fi app provides comprehensive network management capabilities that go beyond basic router administration. If you have smart home devices, the app will be especially useful. Users can monitor data usage patterns, set parental controls for specific devices, prioritize bandwidth for critical applications, and troubleshoot connection issues without requiring technical expertise. It's also convenient to have a network management app when you want to adjust your settings without logging into your router. Installation flexibility includes evening and weekend appointment availability, recognizing that many customers prefer installation times that don't interfere with work schedules. The commitment to next-day installation availability in many areas reflects Fidium Fiber's focus on customer convenience and quick service activation. For customers who prefer to use their existing networking equipment, Fidium Fiber accommodates personal router preferences while ensuring the fiber connection delivers optimal performance.

Quantum Fiber earns high customer satisfaction ratings

Because the split in branding between Quantum Fiber and CenturyLink DSL is still very recent, we have to interpret customer satisfaction rankings that were previously based on the name “CenturyLink” for both brands. Customer satisfaction is much higher for Quantum Fiber than for the DSL provided by CenturyLink. The American Customer Satisfaction Index shows that split in results by dividing “CenturyLink” specifically into fiber and DSL. Fiber (aka, Quantum Fiber) ranks 16 points higher than the DSL service [3]. For Quantum Fiber, these customer satisfaction rankings tell the story clearly. You are likely to have a great internet experience with Quantum Fiber. To avoid confusion, be aware that there is still a certain amount of online cross-marketing between the two companies. Pay attention to the speeds available, whether your internet source labels it “Quantum Fiber” or “CenturyLink.” If the speed is above 200 Mbps, it is a Quantum Fiber product. If the speed is 100 Mbps or below, it is CenturyLink DSL. Overall, we highly recommend Quantum Fiber for its top-of-the-line speeds and reliability, great pricing, and good customer satisfaction ratings.

Reviews are high for Fidium Fiber’s customer service and operations.

Fidium has grown substantially from its initial customer base of approximately 123,000 fiber broadband customers at the end of 2022 [8]. With about 1.56 million current fiber passings and plans to reach about 2 million by the end of 2027 [10], the company has demonstrated significant scaling capabilities in its buildout efforts. The customer service landscape has matured considerably since launch. Fidium has earned one of the industry's highest Net Promoter Scores [1,2], indicating the company has successfully addressed many of the operational growing pains typical of new fiber providers. Early customer complaints about installation delays, communication issues, and service inconsistencies have been resolved as the company refined its processes and expanded its workforce. The local technician model continues to differentiate Fidium from national providers, offering more personalized service and a deeper knowledge of regional infrastructure challenges. Customer service quality has become more consistent across markets as the company has standardized operations and increased staffing levels to meet growing demand. Beyond the continued absence of data caps and contracts, Fidium has expanded its customer-focused approach across all service lines. The company's operational improvements have resulted in more reliable installation schedules, improved communication with customers, and more consistent delivery of promised speeds, addressing the specific pain points that characterized early customer feedback. With funding opportunities through the Broadband Equity, Access, and Deployment program [10], Fidium is positioned to accelerate its rural expansion strategy while maintaining the service quality improvements that have driven its high customer satisfaction ratings.
