AT&T vs. Optimum Internet plan comparison




AT&T offers one of the best values in internet service—fast fiber internet speeds at reasonable prices, plus some of the best support in the business and rock-solid reliability. With no contracts, no data caps, and no monthly equipment fee, AT&T is one of the best home internet providers we tested.
If you can get fiber internet from Optimum , you'll get great all-around service with fast speeds and reasonable pricing. If you can get only cable internet, you'll get slower max speeds and may see different pricing. Both options are decent, but watch out for third-year price hikes and potential customer service hassles.
The AT&T fiber plans represent an excellent value proposition. The speeds are competitive, and the prices at any given tier are lower than nearly every other provider. One exception, Xfinity, offers slightly cheaper gig plans in some markets. Another, Google Fiber, offers $10 less on gigabit speeds. However, AT&T is more likely to be available in areas that have cable internet from Spectrum and Cox, and we think AT&T fiber is usually the better deal.
For the money with AT&T, you get outstanding download speeds and excellent upload speeds. And with unlimited data on fiber internet plans, you can actually use your gigabit connection without worry.
Some legacy customers may have DSL internet from AT&T. The most affordable AT&T plan is more than $50 per month, but this can either be basic DSL (speeds up to 75 Mbps) or the excellent, fiber-based Internet 300. If you can get only AT&T fixed wireless, you’ll pay higher prices, face data caps, and suffer through 1 Mbps upload speeds. Other providers just offer much better deals on plans in these tiers.
Optimum offers a lot for the money. Both fiber and cable internet plans start at 300–500 Mbps, with a very competitive price that beats the entry-level plan for competitor Spectrum and is way less than national benchmarks (1). That's plenty fast for most online gaming and work from home needs, but you can pay for even higher speeds if you have a big household.
Compared to the competition, the two lower-tier plans almost always offer more speed for the money. And while you can technically find cheaper gig plans, Optimum still tends to be the most affordable in its markets.
If you qualify only for cable internet with Optimum, your speeds will be slower but you'll pay about the same every month. Prices are higher than other cable internet providers at these speeds, but you may not have a choice. Most areas that don't have fiber internet won't have multiple cable internet options.
We love the low starting prices, 2-year price lock, and 60-day money back guarantee, but you can expect prices to jump $35–$85 in your third year of service.
AT&T claims 99% reliability (1) for its fiber internet service, and that’s pretty accurate in our experience. In fact, over several years of constant daily use in a packed house (two people working from home, two kids doing schoolwork, lots of streaming video and calls), we haven’t had a single major disruption. This is a marked contrast to our previous provider.
Additionally, speeds are consistent, with little variation based on the time of day, activity, or even the particular speed test used. Its median download speeds are slightly slower than its cable and fiber internet competitors, but only by a matter of milliseconds (2). This all adds up to a great experience where the service “just works,” and nobody ever really needs to wonder if they’ll be able to do what they need to do.
It's also worth mentioning that because AT&T fiber internet uses fiber-optic cables, upload speeds are equal to download speeds. That means you can upload huge files in seconds, video chat, live stream game play, and more without a hiccup.
Optimum performance is solid. With speeds up to 2 Gbps (12000 Mbps) in some states, there’s enough bandwidth available for even the heaviest of streaming households. Even the lowest-tier plans offer plenty of speed for most use cases. The cable service is generally very reliable, as well, and usually even faster than advertised, with better latency than any cable competitor. (2)
Additionally, Optimum offers fiber internet service in some of its coverage areas, which offers extra reliability and symmetrical speeds. That’s an excellent feature for content creators and anyone who shares a lot of large media files. Recently, it started offering home internet plans up to 5 Gbps, a speed that’s nearly impossible to beat.
AT&T fiber internet installation is about as simple as it gets. You have two options: a $99 professional installation by an AT&T technician or a DIY self-install kit.
If you can get only DSL with AT&T, the equipment is still free but you'll be charged a $49 activation fee. If you don't want to self-install, you can have a pro come out for an additional $99.
The self-install is very easy and comes with clear instructions, so we’d recommend that for pretty much everyone. Activation and configuration of your Wi-Fi network are handled through the simple AT&T Smart Home Manager app, so you don’t even need to log into the router settings page like with some other providers.
It is worth noting that both of these charges are a bit higher than what the competition charges. CenturyLink doesn’t charge for self-installation, for example, while Xfinity charges only $89.99 for a professional install.
That said, if you do need a professional to come out, you can count on fast and friendly service. We’ve personally had techs out on a couple of occasions and were happy with the experience.

Finally, the AT&T wireless gateway is surprisingly nice. Called AT&T Smart Wi-Fi, it’s super simple to set up, provides solid range, and looks decent on a desk. Compared to the routers and gateways provided by some other providers, this one’s a breath of fresh air.
Optimum offers a fairly standard wireless gateway with both its fiber and cable plans. The combined modem and router are usually free, but may cost you $10 per month on top of your bill in some areas. You can also add Wi-Fi extenders for $3 each per month, which is handy for larger homes and offices (and not a bad price, either).
If you want to use your own equipment instead of Optimum's free gear, you may run into difficulties. Optimum doesn't list compatible equipment and requires at least some third-party modems to be purchased from its stores.
With Optimum installation, you can do it yourself or have a pro help, and either way is free. If you order online, you can opt for a free standard professional installation or pay $59 for a premium installation, where the tech will configure Wi-Fi on up to six devices for you. While other providers may offer to set up your main device during installation, we haven’t seen such an extensive guarantee elsewhere. This could be a selling point for less tech-savvy customers.
Internet providers have traditionally had a terrible reputation for customer service, but AT&T scores above average with national rating organizations like the American Customer Satisfaction Index (ACSI). These ratings have improved over the last few years, which is encouraging.
AT&T offers several options for getting help:
The support site also has lots of information available. It’s easy to use, and if you do need more help, the options involving service reps usually get a quick, friendly response. While it’s not perfect 100% of the time, AT&T customer support tends to be better than average.
AT&T makes it easy to stay connected away from home, too. Subscribers get access to a nationwide network of free Wi-Fi hotspots. Since AT&T offers mobile phone service in addition to internet, you'll be able to log on in from almost anywhere.
Optimum provides a good customer experience overall. Both types—cable and fiber—are fast and stable, and we haven’t seen any major complaints about reliability. We think the day-to-day experience with Optimum is fine.
However, the company’s customer service is less than stellar, with one of the lowest ratings of all providers, according to the American Customer Satisfaction Index (ACSI) (3). Most of the complaints we’ve seen involve a poor experience dealing with customer service reps. Optimum does offer solid online support options, so you may be able to get around these issues. And, of course, not everyone has a poor experience.
