Quantum Fiber vs. Fidium Fiber Internet Providers Compared

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

Quantum Fiber is a fiber-optic network under the parent company Lumen Technologies, which also operates CenturyLink’s DSL-based service. According to data from December 2024, the Federal Communications Commission states that Quantum Fiber is available to just over 2.2% of U.S. households, making it one of the largest fiber-optic networks in the United States [1]. The service operates in 18 states, as well as a number of cities, with the strongest coverage in Arizona, Colorado, Florida, Iowa, Minnesota, Nebraska, Oregon, Utah, and Washington [2]. In May 2025, AT&T announced plans to acquire Quantum Fiber's parent operations for nearly $6 billion—the transaction is expected to close in 2026 [3]. AT&T has indicated no immediate changes are planned, and they will continue to "prioritize putting customers first" following the acquisition. The sale ultimately resulted in Lumen reporting $915 million in losses for Q2 2025, with Lumen attributing losses to the accounting changes, and "not from money actually spent" [4]. Quantum Fiber delivers symmetrical fiber-optic speeds ranging from 500 Mbps to 8,000 Mbps in select markets, with no data caps or contract requirements. The service stands out for its "Price for Life" guarantee, which locks in your monthly rate permanently—a significant advantage in an industry where 63% of customers reported price increases in the past year [5].

Great prices and a Price-for-Life Guarantee.

Quantum Fiber offers straightforward pricing that includes an autopay discount. Monthly costs are approximately $5 higher if you don't enroll in automatic payments. In most markets, the two primary plans available are the 500 Mbps and 1,000 Mbps (1 Gig) tiers. Multi-gigabit options—including 3 Gig and 8 Gig plans—are available in select areas. A handful of markets, including Ocala and Orlando, Florida, as well as Portland, Oregon, and Vancouver, Washington, offer a budget-friendly 200 Mbps plan for $45 monthly [6].

Plan	Download Speed	Upload Speed	Monthly Price
Up to 500 Mbps	500 Mbps	500 Mbps	$50
Up to 940 Mbps	940 Mbps	940 Mbps	$75
Up to 3 Gbps	3,000 Mbps	3,000 Mbps	$100
Up to 8 Gbps	8,000 Mbps	8,000 Mbps**	$165

*Pricing varies by market **Note: The 8 Gig plan offers asymmetrical speeds with upload capped at 3,000 Mbps  All plans include free equipment rental during an initial period, unlimited data, and no contracts [7].

Value Analysis

When evaluating internet plans, the cost per megabit provides insight into true value. Quantum Fiber's entry-level 500 Mbps plan at $50 monthly translates to 10 cents per Mbps—a competitive rate for fiber service. This pricing structure positions Quantum Fiber favorably against cable providers that may advertise lower starting prices, but dramatically increase rates after promotional periods expire.

Fees and the Price-for-Life Guarantee

Quantum Fiber’s "Price for Life" guarantee permanently locks in your plan rate, which is a fantastic deal. Unlike most cable internet providers that raise prices after the promotional period of one or two years, Quantum Fiber maintains your original rate indefinitely. If you sign up for the 500 Mbps plan at $50 a month, that rate remains frozen even if the same plan later costs new customers $65. This guarantee applies specifically to your base service rate. Three potential cost increases are still possible:

1. Equipment rental fees: Quantum Fiber provides free equipment during an "initial period," but this timeframe is not clearly defined. After this period ends, rental fees may apply. You can drop these fees altogether by using your own compatible router.
2. Installation costs: Professional installation is currently free, though Quantum Fiber states this "could change in the future," and additional products or services might incur extra installation costs.
3. Taxes and miscellaneous fees: Local and state taxes or regulatory fees may increase over time, independent of Quantum Fiber's control.

No Data Caps or Contracts

All Quantum Fiber plans include unlimited data, allowing unrestricted internet use within the acceptable use policy without overage fees or speed throttling. The absence of contracts means you can cancel or modify service anytime without early termination fees.

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. Fidium Fiber's 1 Gig plan, at $55 per month, translates to approximately 5.5 cents per Mbps—among the most competitive rates in the fiber industry. By comparison, entry-level fiber from providers like AT&T or Verizon typically ranges from 10-15 cents per Mbps. 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.

Symmetrical upload and download speeds and superior reliability during peak usage times.

Quantum Fiber utilizes fiber-optic technology, which provides two key advantages over cable and DSL: symmetrical upload and download speeds, and superior reliability during peak usage times. Symmetrical speeds mean your upload capacity matches your download speed. On the 500 Mbps plan, for instance, you receive 500 Mbps in both directions. This proves valuable for video conferencing, uploading large files, livestreaming, and cloud backups—activities that require only modest upload speeds (typically 10 Mbps or less) but benefit from having bandwidth headroom available.

Fiber-to-the-Home vs. Fiber-to-the-Curb

In most installations, Quantum Fiber deploys Fiber-to-the-Home (FTTH), where fiber-optic cable runs directly to your residence. This provides the fastest possible speeds with full symmetrical performance. However, in some cases, Quantum Fiber may install Fiber-to-the-Curb (FTTC), where the final connection to your home uses coaxial cable. Even a short coaxial cable segment will reduce upload speeds compared to pure fiber. If you receive an FTTC connection, your download speeds may remain at advertised levels, but uploads will be slower than the symmetrical speeds typical of FTTH. Before installation, confirm which connection type your location will receive.

Performance Capacity

A gigabit fiber plan from Quantum Fiber supports about 10 devices at once, engaging in high-bandwidth activities (like 4K streaming and online gaming) while maintaining a smooth performance. The combination of low latency, high bandwidth, and consistent speeds makes fiber particularly well-suited for households with multiple heavy internet users.

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. According to Federal Communications Commission data, Fidium Fiber currently reaches approximately 1.56 million fiber passings across more than 700 communities in eight states. The company plans to expand to 2 million passings by the end of 2027, with coverage concentrated in the Northeast—particularly Maine, New Hampshire, and Vermont. Secondary markets include Illinois, Minnesota, and Texas, while California, Pennsylvania, and other states have more limited availability. 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

Quantum Fiber provides its 360 Wi-Fi equipment at no additional cost during an initial period. This system includes a SmartNID ONT device and up to four mesh Wi-Fi pods. The number of Wi-Fi pods will be determined by your installation technician based on your home's size. Most equipment has Wi-Fi 6 connectivity, but Wi-Fi 7 is available in select areas. The mesh network architecture offers better coverage than traditional single-router setups. This is beneficial for larger homes or properties with thick walls that impede wireless signals. The 360 Wi-Fi system creates whole-home connectivity by placing pods throughout your space, eliminating dead zones and ensuring seamless handoff as you move between areas. This setup supports the high device counts and bandwidth demands typical of modern households.

Professional Installation

Quantum Fiber currently provides free professional installation. The company has noted this "could change in the future," and customers requiring additional products or services may incur extra installation costs. Professional installation ensures proper fiber-optic connection, optimal equipment placement for your home's layout, and immediate resolution of any technical issues. The installation process:

• Running fiber-optic cable to your home (FTTH) or to the curb (FTTC)
• Installing the SmartNID ONT
• Positioning mesh Wi-Fi pods throughout the home
• Testing connection speeds and performance
• Explaining system features and troubleshooting resources

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 ratings often skewed by CenturyLink

According to the 2025 American Customer Satisfaction Index (ACSI) report, Quantum Fiber scored 71 out of 100 points—a 7% decline from the previous year. This places Quantum Fiber four points below the fiber industry average of 75 [3]. The 2025 ACSI data also indicated overall fiber provider scores decreased by 1% year-over-year across the industry [8]. The J.D. Power 2024 U.S. Residential Internet Service Provider Satisfaction Study did not differentiate between Quantum Fiber and CenturyLink DSL, instead reporting combined results for Lumen Technologies. In the West, where Quantum Fiber has its strongest presence, Lumen Technologies ranked last with a score of 511 out of 1,000. This combined scoring methodology means CenturyLink's lower-performing DSL service likely impacted the overall rating. If you compare fiber and DSL services within the Lumen portfolio, the ACSI shows Quantum Fiber's fiber service scores 16 points higher than CenturyLink's DSL offerings. This gap showcases that fiber customers report better experiences than DSL subscribers. The 7% satisfaction decline and below-average ACSI score suggest Quantum Fiber has customer experience downfalls regardless of its technical advantages. Issues affecting its customer experience ratings likely include installation delays, equipment problems, billing discrepancies, and customer service responsiveness. Reddit backs this up, with some users frustrated with Quantum Fiber's reliability: "The speed is great, consistent 550mbps up and down, but it is so unreliable" [9]. Other subscribers report a more positive experience, but do note that they are utilizing their own equipment instead of the Quantum Fiber-supplied equipment: "Love [Quantum Fiber], just get your own wifi equipment" [10]. Despite the below-average satisfaction scores, Quantum Fiber remains a strong technical choice where available. The combination of fast symmetrical speeds, unlimited data, no contracts, competitive pricing, and the price-for-life guarantee creates genuine value.

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.
