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 4.3 million subscribers receive cable internet service. But the ISP is also adding some all-fiber connections in select markets. Optimum is the internet brand name of Altice USA, which rolled 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 those prices will be locked for 2 years. 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 those two years, standard prices will take effect, which will spike your bill higher. 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 two-year promotion.

Frontier will give you a good deal on fiber, but DSL varies widely

Frontier is the 8th-largest internet service provider in the United States, with 2.8 million broadband subscribers [1]. The company has a total of 9.9 million copper passings and 6.8 million fiber passings. At the end of 2023, over 70% of their customers were fiber internet customers [2]. Frontier’s main distinction among fiber internet providers is that you will get faster speeds compared to the competition. For example, Frontier’s first-tier fiber plan costs about $39.99 per month at present, like many of its rivals. But that Frontier plan will give you 100 Mbps download and upload speeds, where many other fiber providers tend to start at 200 Mbps and 300 Mbps. With modem-router rental included and no data caps, Frontier Fiber offers the kind of simple, clear pricing that earns high ratings from us. The only drawback is that Frontier Internet (the name for their DSL plans) does not provide the same kind of bargain. Frontier pricing is just average for DSL in the industry. Plus, the DSL speed you will be able to get at your address will vary depending on infrastructure. (DSL usually ranges from 3-50 Mbps download and 1-3 Mbps upload.) 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. Optimum’s current fiber internet customer base is small but has doubled in the last couple of years from around 100,000 to over 200,000 subscribers [4]. By 2025, Optimum plans to create over 6.5 million fiber passings [5]. Fiber internet’s most striking advantage over cable internet is that fiber offers symmetrical upload and download speeds. This is a game-changer for online gaming, videoconferencing, and large homes with multiple devices. When Altice merged Suddenlink under the Optimum brand, the company had two distinct “footprints” left from where the old 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 in the next year or two will be 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 7000 Mbps. That’s right up there with the top few providers in the fiber internet business. And pricing for the 2 Gig and 5 Gig plans is cheaper than comparable offerings from other ISPs. 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. DSL performance will be unpredictable, but 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.

No equipment rental fees, free installation with Optimum plans

Optimum will provide your modem/router as part of your monthly plan fee, with no extra rental charge. If you have a compatible cable plan, you may even get a Wi-Fi 6 router, which will give you higher speeds for multiple devices than Wi-Fi 5. Fiber internet plans from Optimum will often include the Wi-Fi 6 gateway as well. 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 Optimum plans.

Installation fees waived with one year of service

Frontier provides your basic modem/router at no charge when you get fiber internet or DSL. For both technology types, standard installation fee is $100, but the fee is waived as long as you keep your service for at least 12 months. So, you basically get free installation unless you cancel before the year is over, in which case you'll pay a pro-rated fee.

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 random sampling of online user reviews seems to indicate 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 around to different departments, and getting contradictory responses from different phone reps when trying to solve billing issues. Because this is a fairly even distribution of complaints, it’s likely that Optimum is just not quick enough in responding to customer concerns, whether they be 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 gets better ratings, we have to give them only 3 stars for customer satisfaction.  

Frontier Fiber shows strong performance in customer satisfaction

Frontier's reviews have improved greatly with increased fiber service, as is reflected in higher rankings in the J.D. Power Residential Internet Service Provider Satisfaction study [3]. Frontier's sharp rise in the rankings is a promising sign that if you get Frontier Fiber, you will be happy with your choice. In addition, Frontier outranks even strong fiber competitors in the well-regarded national survey known as Net Promoter Score [4].
