Optimum vs Frontier: A Comprehensive Comparison

Frontier and Optimum used to be very different internet providers. Back when this comparison was originally written in 2021, Frontier was primarily a DSL company with slow speeds, spotty reliability, and a reputation that matched. Optimum was a regional cable provider serving the northeast. Putting them side by side was barely a fair fight.

That is no longer the case. Frontier filed for Chapter 11 bankruptcy in 2020 and emerged in 2021 as an entirely different company. They invested billions of dollars in fiber optic infrastructure and began aggressively retiring the old copper and DSL lines that gave them such a poor reputation. Frontier is now a fiber-first ISP with symmetric speeds, competitive pricing, and no contracts.

Optimum has changed too. Its parent company, Altice USA, started building out a fiber optic network to compete with Verizon Fios and other fiber providers in the northeast. Where Optimum Fiber is available, it now offers symmetric speeds that rival anything on the market.

In Connecticut – the state where Frontier and Optimum overlap most – both providers now offer fiber internet plans. The comparison is far closer than it was a few years ago. If you are choosing between them today, the old framing of fast cable versus slow DSL no longer applies. This is now a fiber-versus-fiber matchup in many areas.

All pricing and plan details below reflect what was available as of 2024-2025. Both providers update their offerings regularly, so check their websites for current pricing at your specific address before signing up.

How Much Does Frontier Fiber Cost vs Optimum

Frontier’s fiber pricing is one of the cleanest in the industry. There are no promotional rates that jump up after 12 months. No contracts. No hidden fees tacked onto your second bill. The price you see when you sign up is the price you keep paying. That alone separates Frontier from most cable and fiber competitors.

Frontier offers four fiber tiers. Fiber 500 delivers 500 Mbps symmetric for about $49.99 per month. Fiber 1 Gig runs around $69.99. Fiber 2 Gig is approximately $99.99. And Fiber 5 Gig sits at roughly $154.99 per month. All of these are standard monthly rates with no introductory gimmicks.

Optimum takes a different approach. Their advertised prices are promotional – typically valid for the first 12 months. Internet 300 starts at about $40 per month. Internet 500 is around $60. Fiber 1 Gig is approximately $80. Fiber 2 Gig lands near $120 per month. Those numbers look competitive on the surface.

The catch is what happens after the promotional period ends. Optimum’s monthly rate increases – sometimes by $20 to $30 or more – once the introductory pricing expires. If you are not the type to call and negotiate a retention deal every year, you end up paying significantly more than the advertised rate.

At the 1 Gig tier, the math is straightforward. Frontier charges $69.99 per month with no price increase coming. Optimum charges around $80 per month during the promotional period and more after that. Frontier wins on long-term value at this speed tier, and the gap only widens after Optimum’s promo pricing expires.

Speed Tier	Frontier Price	Optimum Price	Contract Required
300 Mbps	Not offered (starts at 500)	~$40/month (promo)	Optimum: may require term commitment
500 Mbps	~$49.99/month	~$60/month (promo)	Frontier: no contract. Optimum: may require term commitment
1 Gig	~$69.99/month	~$80/month (promo)	Neither requires a contract at this tier
2 Gig	~$99.99/month	~$120/month (promo)	Neither requires a contract at this tier
5 Gig	~$154.99/month	Not widely available	Frontier: no contract

If you are disciplined about switching providers or renegotiating when promotions expire, Optimum’s lower introductory rates can save you money in the first year – particularly at the 300 Mbps tier, where Frontier does not even compete. But if you prefer a predictable bill with no surprises, Frontier’s flat-rate pricing is hard to beat.

Is Frontier Still a DSL Provider

This is the most outdated misconception about Frontier. For years, Frontier was known as a DSL company that sold 6 to 25 Mbps connections over old copper phone lines. If you read reviews from 2019 or 2020, you will see complaints about slow speeds, frequent outages, and customer service that matched the quality of the product. All of that was deserved at the time.

That version of Frontier is mostly gone. After emerging from Chapter 11 bankruptcy in 2021, the company committed billions of dollars to building a fiber optic network and retiring its copper infrastructure. The goal was to transform from a legacy DSL provider into a modern fiber ISP. That transformation is well underway.

Frontier still has legacy DSL service in some areas where fiber construction has not been completed. These DSL plans offer speeds in the 6 to 25 Mbps range and are being actively phased out. Frontier is not marketing DSL to new customers in areas where fiber is available. The DSL product exists only as a holdover while fiber buildout continues.

Where Frontier has completed its fiber rollout, the service is symmetric. The 500 Mbps plan gives you 500 Mbps up and 500 Mbps down. The gigabit plan delivers 1,000/1,000. The 2 Gig plan delivers 2,000/2,000. These are real fiber speeds, not DSL speeds relabeled with marketing language.

If you are at an address where only Frontier DSL is available – no fiber – then Optimum Cable or Optimum Fiber will be significantly faster. Do not sign up for Frontier DSL in 2025 if you have any alternative available. But do check back periodically. Frontier’s fiber rollout is happening rapidly, and addresses that only had DSL six months ago may now have fiber as an option.

Where Do Optimum and Frontier Overlap

The primary overlap market for these two providers is Connecticut. Frontier serves parts of Connecticut where it acquired AT&T’s former service territory. Optimum also serves parts of Connecticut through the infrastructure that Cablevision originally built, now operated under the Altice USA umbrella.

In Connecticut, there is a genuine chance that both Frontier Fiber and Optimum are available at your address. This is the market where the head-to-head comparison matters most, and where both companies are actively competing for subscribers.

Outside of Connecticut, the overlap is minimal. Frontier’s fiber network is concentrated in parts of Florida, California, Texas, Indiana, and the Carolinas. Optimum’s service territory covers New York, New Jersey, Connecticut, and small parts of Pennsylvania. The geographic footprints barely touch outside of the CT market.

Frontier does have some legacy DSL service in parts of New Jersey and New York, but those areas are small and being migrated to fiber. If you live in New York or New Jersey and see Frontier listed as an option, check whether the service available at your address is fiber or DSL before proceeding. The experience is drastically different depending on which one you get.

The best way to find out what is available is to check both providers’ websites with your specific address. Availability can vary block by block, especially in areas where fiber construction is still in progress.

When checking Frontier’s website, pay close attention to whether the plans shown are fiber or DSL. The plan names and speeds will tell you. If the fastest option at your address is 25 Mbps or less, you are looking at DSL. If you see 500 Mbps and above with symmetric speeds, that is fiber. With Optimum, check whether the plans listed are cable or fiber – the upload speed listed alongside each plan is the giveaway.

Frontier vs Optimum Upload Speeds

Upload speed is one of the biggest differentiators in any ISP comparison, and it depends entirely on the type of connection. Fiber delivers symmetric speeds. Cable does not. That distinction matters a lot when you are comparing Frontier Fiber to Optimum Cable.

Every Frontier Fiber plan is fully symmetric. The 500 Mbps plan gives you 500 Mbps down and 500 Mbps up. The 1 Gig plan delivers 1,000/1,000. The 2 Gig plan delivers 2,000/2,000. Upload speed always matches download speed across the board.

Optimum Cable plans are heavily asymmetric. The 300 Mbps download plan typically delivers only 20 to 30 Mbps upload. The 500 Mbps plan might give you 30 to 40 Mbps up. Even at the 1 Gig tier, cable uploads usually top out around 50 Mbps. That is a significant gap.

Optimum Fiber plans, where available, are symmetric – matching upload to download, just like Frontier. If both providers are offering fiber at your address, upload speeds are equivalent and this category is a wash.

Provider and Plan	Download Speed	Upload Speed	Connection Type
Frontier Fiber 500	500 Mbps	500 Mbps	Fiber (symmetric)
Frontier Fiber 1 Gig	1,000 Mbps	1,000 Mbps	Fiber (symmetric)
Frontier Fiber 2 Gig	2,000 Mbps	2,000 Mbps	Fiber (symmetric)
Optimum Cable 300	300 Mbps	~20-30 Mbps	Cable (asymmetric)
Optimum Cable 500	500 Mbps	~30-40 Mbps	Cable (asymmetric)
Optimum Cable 1 Gig	1,000 Mbps	~50 Mbps	Cable (asymmetric)
Optimum Fiber 1 Gig	1,000 Mbps	1,000 Mbps	Fiber (symmetric)
Optimum Fiber 2 Gig	2,000 Mbps	2,000 Mbps	Fiber (symmetric)

If you are comparing Frontier Fiber against Optimum Cable, Frontier wins on upload speed by a massive margin. The difference between 500 Mbps upload and 30 Mbps upload is not subtle. Video calls, cloud backups, security camera footage uploads, Twitch streaming, and remote desktop sessions all depend on upload bandwidth.

A single Zoom or Teams call in HD uses roughly 3 to 4 Mbps upload. One person on a call is fine even on cable. Two people on simultaneous calls with a third person backing up files to Google Drive is where cable uploads start to buckle. With fiber, you would not even notice those three activities running at the same time.

If you work from home or have multiple people in the household who need reliable upload speeds, this is the most important comparison point. Frontier Fiber handles upload-heavy workloads without breaking a sweat. Optimum Cable makes you ration your upload bandwidth.

Do Frontier or Optimum Have Data Caps or Contracts

Frontier’s approach to data caps and contracts is simple. There are no data caps on any plan. There are no contracts. There are no early termination fees. You sign up, you pay month to month, and you cancel whenever you want without penalties. That is the entire policy.

Optimum does not impose data caps either. You can use as much data as you want each month without overage charges or throttling. On that front, both providers treat customers the same way.

The contract situation with Optimum is more nuanced. Optimum’s promotional pricing – those lower introductory rates for the first 12 months – may require a term commitment. If you sign up for a promotional rate and cancel before the term is up, you could face an early termination fee. The specifics depend on your plan and your area, so read the terms carefully before signing up.

Frontier’s no-contract approach eliminates that concern entirely. There is no fine print about early termination fees because there is no contract to terminate early. If Frontier’s service is not meeting your expectations, you cancel and stop paying. No phone call to a retention department. No fee for leaving.

Feature	Frontier Fiber	Optimum
Data Caps	None	None
Contract Required	No	Promotional plans may require a term
Early Termination Fee	None	Possible with promotional pricing
WiFi Router Included	Yes, no monthly fee	Varies by plan – rental fee may apply
Price Increases After Promo	No promotional pricing	Yes, rates increase after 12 months
Self-Install Option	Available for some setups	Available in some areas

If you value transparency in billing, Frontier’s model is cleaner. You know what you are paying from month one, and that number stays the same. Optimum’s promotional pricing can save you money in the short term, but you need to be aware of what the price becomes after the introductory period ends – and be prepared to renegotiate or switch if the post-promo rate does not work for you.

Frontier vs Optimum Equipment and Installation

Frontier includes a WiFi router at no extra cost with all of its fiber plans. There is no monthly equipment rental fee. The router is part of the service. This is a meaningful difference from providers that charge $10 to $15 per month for equipment rental, which adds $120 to $180 per year to your actual cost.

Standard installation for Frontier Fiber is free. A technician comes to your home, runs the fiber line, sets up the router, and verifies the connection. Self-installation is available for some setups where fiber infrastructure is already in place at the address. Either way, you are not paying an upfront installation fee for standard fiber service.

Optimum’s equipment situation depends on the plan. Some plans include a gateway or router. Others charge a monthly rental fee for the equipment. The specifics vary by plan tier and service area. Smart WiFi features – mesh networking extenders for larger homes – may carry additional monthly charges on top of the base internet price.

Installation costs with Optimum also vary. Professional installation may be free with certain promotions or plan commitments, but standard installation can carry a fee in other situations. Self-install kits are available in some areas.

Frontier’s included router with no monthly fee is a clear advantage. Over the course of a two-year period, a $10 per month equipment rental fee adds $240 to your total cost. That amount erases most or all of any promotional savings Optimum might offer in the first year. When comparing total cost of ownership, factor in equipment fees – not just the advertised monthly price.

Both providers support bringing your own router. If you already own a compatible WiFi 6 or WiFi 6E router, you can use it with either service. Frontier does not charge a fee for using your own equipment, and their included router is a reasonable option for most households even if you choose to use it instead of buying your own.

For larger homes where a single router does not cover every room, both providers offer mesh WiFi options. Frontier sells eero mesh units that integrate with their fiber service. Optimum offers Smart WiFi extenders, though these may come with an additional monthly fee. If you already have a mesh system like Google Wifi, eero, or TP-Link Deco, it will work with either provider’s fiber service.

Frequently Asked Questions

Is Frontier still slow?

No. Frontier’s reputation for slow speeds comes from its legacy DSL network, which offered 6 to 25 Mbps over old copper phone lines. That product is being phased out. Where Frontier has built fiber, speeds start at 500 Mbps and go up to 5 Gbps – all symmetric. If fiber is available at your address, Frontier is fast. If only DSL is available, it is still slow. Check what type of service is offered at your specific address before judging the company based on old reviews.

Does Frontier have fiber in Connecticut?

Yes. Connecticut is one of Frontier’s most developed fiber markets. Frontier acquired AT&T’s former service territory in Connecticut and has been investing heavily in replacing the old copper lines with fiber optic infrastructure. Many addresses in the state now have access to Frontier Fiber with speeds from 500 Mbps to 5 Gbps. The rollout is ongoing, so if fiber is not yet available at your specific address, it may become available in the near future. Check Frontier’s website periodically for updates.

Is Frontier or Optimum cheaper?

It depends on the timeframe. Optimum’s promotional pricing is lower in the first 12 months. Internet 300 at $40 per month and Internet 500 at $60 per month undercut Frontier’s starting price of $49.99 for 500 Mbps. But after the promotional period ends, Optimum’s rates increase significantly. Frontier does not use promotional pricing – the rate you sign up at is the rate you keep paying. Over two or three years, Frontier’s flat-rate pricing often works out to be equal or cheaper than Optimum’s post-promo rates, especially at the 1 Gig tier and above.

Do Frontier or Optimum require contracts?

Frontier does not require contracts on any of its fiber plans. You pay month to month and can cancel at any time without early termination fees. Optimum’s contract requirements depend on the plan and promotion you sign up for. Some promotional pricing comes with a 12 or 24-month term commitment, and canceling before the term is up may result in an early termination fee. If avoiding contracts is important to you, ask explicitly about term commitments before signing up with Optimum, and read the terms of service carefully.

Does Frontier still offer DSL?

In some areas, yes. Frontier still has active DSL service at addresses where fiber construction has not been completed. These DSL plans deliver speeds in the 6 to 25 Mbps range and are not being offered to new customers where fiber is available. Frontier is actively phasing out its DSL network as fiber buildout continues across its service territory. If you check your address and only see DSL plans from Frontier, consider Optimum or another provider as your primary option. Check back in a few months – your address may gain fiber availability as construction progresses.

Which has better customer service – Frontier or Optimum?

Neither provider is known for exceptional customer service, and both have earned low marks in J.D. Power surveys and customer satisfaction studies. Frontier’s customer service reputation took a beating during its DSL era, though the company has made efforts to improve support quality alongside its fiber buildout. Optimum – operating under the Altice USA brand – has also faced criticism for long wait times and billing disputes. If customer service is a top priority, check recent reviews specific to your local market. Service quality can vary by region, and a provider’s national reputation does not always match the local experience.
