Frontier Internet is a United States-based internet service provider with roots in telecommunications that stretch back several decades. Today, they operate as a residential and business ISP with a growing focus on fiber internet, particularly in suburban and rural markets where high-speed options have traditionally been limited. Their network combines newer fiber infrastructure with legacy copper systems, reflecting a company in the midst of a long-term transition toward fiber-first service. Their internet offerings center on unlimited data, no annual contracts, and symmetrical upload and download speeds on fiber plans. Frontier also offers multiple speed tiers, including multi-gig options in select areas, along with business internet solutions designed for small companies outside major metro regions. Wi-Fi equipment, professional installation, and managed Whole Home Wi-Fi are available depending on plan and location. Customer feedback around Frontier varies by platform and region. Reviews often point to strong technician interactions and solid performance on fiber connections, while billing complexity, promotional pricing changes, and legacy network limitations remain recurring concerns. From an industry standpoint, Frontier holds a Better Business Bureau headquarters rating of A+ and is frequently referenced for their continued investment in fiber expansion.
Optimum, operating under their parent company Altice USA, are a major telecommunications provider headquartered in Long Island City, New York. Their core service area spans 21 states, with a strong concentration in the Northeast. The company provides internet, TV, and mobile services, with their most compelling offerings being their expanding fiber-optic network. Standout features include multi-gigabit speeds up to 8 Gbps, a "Price for Life" price lock guarantee on select fiber plans, and the inclusion of a Wi-Fi 6 gateway with no equipment fee. For value-seeking customers, Optimum promotes strong bundle discounts, often including a free unlimited mobile line for a year with certain internet plans, and an Affordable Access Program for eligible households. Despite these technical strengths, Optimum's reputation is severely impacted by consistent critical feedback. They hold an F rating from the Better Business Bureau, reflecting a high volume of unresolved customer complaints. Common grievances center on significant price increases after the promotional period ends, considerable difficulties with customer service, including long wait times and unhelpful support, and unreliable service in areas still dependent on its older cable infrastructure. This creates a stark contrast between their capable network technology and a frequently frustrating customer experience.

Frontier vs. Optimum
Frontier and Optimum often end up on the same shortlist because they both serve suburban and rural regions where strong internet options can feel limited. They take very different paths to performance, pricing, and long-term value, which makes the choice less obvious than it seems. This comparison walks you through the essentials so you can decide which one fits your home and how you use the internet.
Speeds and availability
Frontier leans heavily on their expanding fiber network, especially in suburban and rural areas across more than 25 states. Their fiber plans offer symmetrical speeds from 500 Mbps to multi-gig tiers up to 7 Gbps, all with unlimited data. Areas still on legacy DSL see much slower and less competitive speeds, but fiber access continues to grow quickly.
Optimum serves around 21 states, with the strongest coverage in the Northeast and select cities in Texas. They deliver service through both cable and fiber, with fiber offering symmetrical speeds and cable offering fast downloads but limited uploads. Their fiber tiers reach up to 8 Gbps in supported markets, while cable speeds vary by neighborhood. All residential plans include unlimited data, but fiber availability is still limited outside core regions.
Reliability and performance
Frontier’s fiber network offers consistently strong performance, low latency, and stable upload and download speeds. Households on fiber generally see reliable connections for remote work, streaming, and gaming. Service quality drops in DSL areas, where older copper lines introduce speed inconsistencies, higher latency, and more outages. The gap between fiber and DSL remains the biggest factor shaping the Frontier experience.
Optimum’s performance depends heavily on whether your address qualifies for fiber or cable. Their fiber service performs well with steady speeds, low latency, and fewer peak-hour slowdowns. Cable areas are more hit-or-miss. Upload speeds are much lower, congestion is more noticeable, and reviews often mention inconsistent reliability in older network zones. While Optimum’s infrastructure continues to improve, service consistency varies more widely than with providers that operate only one network type.
Pricing and value
Frontier structures their plans around simple monthly pricing, with discounted introductory rates when you enroll in Auto Pay and Paperless Billing. Fiber 500 often starts around $29.99, while multi-gig tiers scale upward from there. They don’t require contracts, and equipment fees are often waived during promotions. Prices usually increase after the first year, but the lack of long-term commitments softens the impact for most households.
Optimum competes aggressively on introductory rates, especially for fiber plans, with budget options starting as low as $15 and multi-gig tiers offering long price-lock guarantees. They include a Wi-Fi 6 gateway at no extra cost, and many plans bundle perks like free streaming trials or a complimentary mobile line for the first year. However, their standard prices jump significantly after promotional periods. Customer reviews frequently note billing changes, unclear fee structures, and frustration during plan transitions, which can reduce the overall value unless you secure one of their long-term price-lock offers.
Conclusion
Frontier fits best if you live in an area with fiber access and want strong upload speeds, unlimited data, no contracts, and predictable performance. Their focus on suburban and rural expansion makes them a strong match for homes that have struggled with limited high-speed options. Optimum works well for households in fiber-ready neighborhoods seeking fast multi-gig tiers, bundle savings, and competitive introductory prices. Cable-only areas should be approached with more caution due to mixed reliability and customer service feedback. If you’re comparing both at your address, checking fiber availability first is the quickest way to narrow your choice and move forward with confidence.
