Optimum vs. Frontier Internet Providers Compared

Optimum features good speeds but poor customer satisfaction scores

Optimum is a major national cable internet provider. Most of Optimum’s 4.4 million subscribers receive cable internet service [7]. But the ISP is also adding some all-fiber connections in select markets--most prominently in the Northeast [8]. Optimum is the internet brand name of Altice USA, which rebranded the company formerly called Suddenlink into the Optimum brand in 2022 [1]. Altice/Optimum is the 6th-largest ISP in the nation [2]. Optimum seems to check off all the right boxes for many of its offerings. You will have no data caps and no required contracts with Optimum internet plans. You will also get free equipment rental included with your monthly plan price. And Optimum’s prices are good (at least while the promotions last). So why are Optimum’s national customer satisfaction scores so low? We’ll check into that as we give you an overview of what to expect from an Optimum internet connection.

Good initial prices followed by price hikes

Cable internet is the chief type of connection that Optimum provides its customers. Because of improvements to cable internet technology, you can get gigabit download speeds from many cable internet companies like Optimum. You just won’t get the same upload speeds from cable as you will from an all-fiber connection [3]. Whether you get the usual cable service or all-fiber, you will get good prices from Optimum, and, on select plans, those prices will be locked for 5 years (as of January 2026) [9]. Here’s an example. You’ll pay $40/month for Optimum’s first-tier plan, which is up to 300. That is a good price for these speeds. The catch is that after the promotional period ends, standard prices will apply, which will increase your bill. That may be why Optimum is seeing year-over-year declines in its cable customers [4]. The price hikes may be pushing people to other options at the end of their promotional period.

Frontier will give you a good deal on fiber, but DSL varies widely Frontier's main distinction among fiber internet providers is competitive pricing on high-speed plans. Fiber internet plans range from $19.99 to $109.99 per month with Auto Pay and Paperless Billing [4]. Current promotional pricing includes Fiber 200 at $39.99/month, Fiber 500 at $29.99/month, and Fiber 1 Gig at $49.99/month—all offering symmetrical upload and download speeds.  With router rental included and no data caps, Frontier Fiber offers the kind of simple, clear pricing that earns high ratings from us. Frontier offers significant sign-up incentives, some of which has included a $300 Visa Reward Card with Fiber 5 Gig and 7 Gig plans, a $200 Visa Reward Card with Fiber 2 Gig, and $10/month off YouTube TV for 12 months. Be sure to check Frontier’s official website for current promotions. The only drawback is that Frontier Internet (the name for their DSL plans) does not provide the same kind of bargain. Frontier's single DSL plan costs $64.99 per month with variable speeds depending on your location. Plus, the DSL speed you will be able to get at your address will vary depending on infrastructure, with customers receiving average download speeds of 30 Mbps and upload speeds of 2 Mbps [5]. Average DSL pricing in the industry is not a great deal for customers compared to cable and fiber pricing. That's why Frontier and many other providers are moving away from copper-based service in favor of fiber.

Cable and fiber both provide fast download speeds, but cable's upload speeds are slower

With hybrid fiber-coaxial (HFC) technology, Optimum gives its cable customers gigabit download speeds but much slower upload speeds. That’s typical for cable internet service. Optimum is comparable to other major cable internet providers such as Spectrum and Xfinity, offering upload speeds at a maximum of around 35-50 Mbps. Optimum differs from the cable internet competition because it is also launching into the all-fiber internet market. As of November 2025, Optimum has over 3 million fiber passings and continues to expand [10]. Fiber internet’s most striking advantage over cable internet is its symmetrical upload and download speeds. This is a game-changer for online gaming, videoconferencing, and large homes with multiple devices. When Altice merged Suddenlink into the Optimum brand, the company had two distinct “footprints” from where the former Optimum and Suddenlink coverage had existed. Suddenlink’s coverage area had been primarily in the South and West. Optimum was strong in the Northeast, and particularly in the tri-state area of New York, New Jersey, and Connecticut. Now, the fiber buildout is fastest in that tristate area [1]. Your chances of getting fiber internet from Optimum is better if you live in the tri-state area.

Frontier Fiber offers speed and reliability, but their DSL lags behind Just like pricing, performance for Frontier plans is heavily split depending on whether you get fiber or DSL. With Frontier Fiber, you can get multi-gigabit speeds up to 7,000 Mbps. That's right up there with the top few providers in the fiber internet business, with Frontier customers receiving average fiber speeds of 6,394 Mbps for both downloads and uploads. Frontier's fiber network delivers true symmetrical speeds—meaning your upload speed matches your download speed—which is particularly valuable for video conferencing, cloud backups, and content creation. These multi-gigabit speeds will be more than sufficient for very large households with many devices all streaming or gaming simultaneously. Even 500 Mbps is still a lot of speed and will be more than capable of supporting a five- or six-person home and all the devices in it. The pending Verizon acquisition commits to completing Frontier's planned expansion to 10 million fiber homes by 2026, ensuring continued network investment and reliability improvements.

DSL performance will be unpredictable, with customers receiving average download speeds of just 30 Mbps and upload speeds of only 2 Mbps. The only constant is that it will not deliver fiber-like performance. If you're lucky, you'll get a speed above 25 Mbps download. With that speed, you'll be able to do most standard internet activities such as streaming and browsing, though you'll have to watch how many devices are online at once. But if you get a speed that's 10 Mbps or lower, you may find your service glitching or freezing during heavy-data tasks. Frontier is actively phasing out DSL in favor of fiber networks, with former CEO Nick Jeffery indicating full copper decommissioning is expected within a three- to five-year timeframe [6].

No equipment rental fees, free installation with Optimum plans

Optimum will provide you with a WiFi 6E gateway as a part of your monthly plan fee, with no extra rental charge [9]. If you would rather use your own modem and router, Optimum will allow it. Just be sure to check for compatibility with their specs. Standard installation is free with most Optimum plans.

Installation fees waived for fiber, included router varies by plan Frontier currently waives installation fees entirely for all fiber plans, while DSL plans have a $100 installation fee that you can avoid by doing self-installation. Every Frontier Fiber plan includes a premium Wi-Fi router at no charge, with the specific model depending on your speed tier. Plans from Fiber 200 through Fiber 2 Gig come with a free Amazon eero Pro 6E router, while Fiber 5 Gig and Fiber 7 Gig plans include the more advanced TP-Link Archer AXE300 6E router. For customers choosing the top-tier 5 Gig plan, Frontier also includes a three-year new tech upgrade guarantee. However, there are some important fees to be aware of if you decide to cancel service. Frontier charges a $100 early termination fee if you cancel within the first 12 months for all fiber plans except the Fiber 2 Gig plan, which has no early termination fee. Additionally, if you fail to return equipment after terminating service, Frontier may charge for non-return equipment fees. There's also a $50 restocking fee if you decide you no longer want your Frontier Fiber service.

Optimum customer satisfaction: the big question mark

With so many seemingly good points to its service and pricing, why has Optimum’s customer satisfaction scored significantly below average according to J.D. Power? [6] A sampling of online user reviews suggests two major complaints. The first is outages and failure of technical response. The second is a more general dissatisfaction with the phone system: being transferred to different departments and receiving contradictory responses from different phone reps when trying to resolve billing issues. Because this is a fairly even distribution of complaints, it’s likely that Optimum is not responding quickly enough to customer concerns, whether they are technical or billing-related. We can’t know the reason for this dysfunction. Often, these kinds of responsiveness issues happen when companies are understaffed or have high staff turnover in their customer service. But until Optimum improves its ratings, we have to give it only 3 stars for customer satisfaction.  

Frontier Fiber shows strong performance in customer satisfaction Frontier's reviews have improved greatly with increased fiber service. In the 2025 American Customer Satisfaction Index (ACSI) report, Frontier scored 71/100 for its fiber service—a significant improvement over its 58/100 score for non-fiber internet [7]. While fiber ISP satisfaction scores tend to run lower industry-wide, with AT&T leading at 78/100, Frontier's fiber performance places it competitively among major providers. Recent customer feedback reinforces these improvements. One Reddit user wrote that their “newly installed 2 Gig fiber [is an] awesome experience so far” [8]. That said, reliability might depend on where you reside, as another Reddit thread had commenters praising their service in Plano, TX, but also reporting outages and inconsistencies in speeds [9]. Frontier's sharp rise in rankings is a promising sign that if you get Frontier Fiber, you will be happy with your choice. The fiber service has earned an overall rating of 3.83 stars specifically, compared to just 2.55 stars for DSL service, highlighting the dramatic difference in customer satisfaction between the two technologies.
