AT&T vs. Optimum

Is AT&T or Optimum better?

The choice between AT&T and Optimum is a fairly easy one. If AT&T Fiber is available in your area, almost everyone should go with that. But if you can only get AT&T’s DSL service — confusingly called AT&T Internet — most people will be better off with Optimum.

Here’s how the two providers compare in every key category:

• Availability: AT&T internet is available in 23 states, while Optimum internet is available in 21. Roughly 48% of AT&T customers have fiber, with the remainder subscribed to AT&T Internet. 
• Price: Because Optimum increases rates by $70/mo. in year two, AT&T is significantly cheaper in the long run, regardless of whether you get its DSL or fiber optic service. 
• Speeds: AT&T Fiber has the edge when it comes to speed. It tops out at 4,700 Mbps in some areas, compared to 940 Mbps for Optimum.
• Customer satisfaction: AT&T receives some of the highest customer satisfaction scores in the industry, while Optimum typically gets some of the lowest.

AT&T vs. Optimum ratings

To compare internet providers, we rated each of them on four categories: affordability, performance, value and customer satisfaction. AT&T Fiber scores way ahead of Optimum in every metric, while it’s more of a toss-up between AT&T Internet and Optimum. AT&T Internet is significantly more affordable, but you won’t get nearly as fast speeds. Overall, customers report fewer complaints with AT&T’s service than Optimum.

How we score internet providers

We evaluate broadband providers in four categories: affordability, performance, value and customer satisfaction. Each category contains multiple sub-factors, all of which are weighted differently to impact the provider’s overall score.

We evaluate broadband providers in four categories: affordability, performance, value and customer satisfaction. Each category contains multiple sub-factors, all of which are weighted differently to impact the provider’s overall score.

For each sub-factor, we score all providers on a continuous scale of one to five, relative to the industry as a whole. Because the average download speed in America is currently 180 Mbps, for example, we assigned all plans with download speeds between 100 and 299 Mbps a score between three and four. Xfinity’s 200 Mbps plan received a 3.50 score for download speed, while Spectrum’s 400 Mbps plan got a 4.16.

We only considered standardized data points in our scoring system. More abstract data like consistency of service and brand reputation is still part of our analysis, but we opted to let our writers address them in the context of each review.

AT&T vs. Optimum contracts, installation, data caps and equipment

Pricing is never simple when it comes to internet service. No matter which provider you choose, you’ll have to factor in a number of extra fees to calculate the final price you’ll see on your monthly bill. Here’s how AT&T and Optimum compare when it comes to added costs:

• Contracts: Neither AT&T or Optimum require contracts for internet service.
• Installation: AT&T and Optimum are both currently waiving installation fees on all internet plans.
• Data caps: AT&T has no data caps on its fiber optic plans and 1GB caps on its DSL plans. Optimum has unlimited data on all plans.
• Equipment fees: AT&T doesn’t have any equipment fees. You’ll pay an extra $10/mo. if you rent your modem/router through Optimum.

AT&T vs. Optimum bundles

AT&T and Optimum both offer internet and TV bundles that can make shopping for home services convenient and save you money in the process. Bundling internet and TV can also get you service or equipment upgrades, like free premium channels or speed upgrades.

AT&T

AT&T doesn’t have its own TV service, but you can bundle DIRECTV Stream Entertainment with AT&T’s Fiber 300 plan.

Optimum

Optimum’s FlexAbility packages offer two and three item bundles with TV service, internet plans and mobile plans.

AT&T vs. Optimum customer satisfaction

With help from about 250,000 real consumers, the American Customer Satisfaction Index (ACSI) gives internet providers an annual score based on evaluations of quality and experience. Additionally, thousands of Consumer Reports readers grade their experience with internet providers every year. Taken together, these scores can be a great way to judge a provider before committing to service. 

Source: ACSI, Consumer Reports

Customers are clearly a lot happier with AT&T. It has the third highest score of any provider with ASCI, while Optimum has the lowest.

The gap wasn’t quite as large with Consumer Reports, but Optimum still earned the lowest possible scores in every category. 

The bottom line

If AT&T Fiber is available in your area, this is an easy choice. It’s both the cheapest and fastest of the two — a rare feat for an internet provider. But if you’re choosing between AT&T Internet (DSL) and Optimum, the decision gets a little more complicated.

Optimum offers far better speeds than AT&T’s DSL plans, but you’ll pay a lot more for them, especially after the first year. In year two, Optimum plans will cost anywhere from $100/mo. to $140/mo. AT&T’s DSL plans, for comparison, cost $55/mo. in year one and $65/mo. in year two.

But AT&T’s DSL plans are usually significantly slower. They range anywhere from 10 to 100 Mbps download speed, and you’ll automatically get the fastest plan available. If the speeds available are on the higher end of that range, you can probably get by just fine. But you’ll struggle to do things like stream video and work from home on just 10 Mbps.
