Plans & Pricing – Optimum vs AT&T Internet

Although AT&T is well known for its incredibly fast and reasonably priced fiber services, it also offers IPBB and fixed wireless internet options more suitable for rural users, with monthly rates as low as $55.00.

On the other hand, a majority of Optimum subscribers get 3-speed tiers for internet through coaxial cables. However, if you reside in one of its expanding fiber locations, particularly in the New York tri-state area, you may get fiber internet speeds of up to 8,000 Mbps (up and down).

Additional Costs – AT&T vs Optimum Internet 

AT&T and Optimum do not charge hefty extra or hidden fees for add-on services as other internet service providers do. They offer free professional installation on online orders, and standard equipment is included in the monthly fee. 

Add-On FeesAT&TOptimum
Standard Equipment Included Included 
Extra Equipment $10.00/mo.*$2.95/mo.**

Data Caps & Overage Fees  

Every AT&T Fiber plan includes unlimited data. Even if you have AT&T Internet Air or an IPBB connection with 100 Mbps speed or higher, you will get unlimited monthly data.

However, AT&T Internet 75 and slower IPBB speed tiers are subject to 1.5 TB data restrictions. Exceeding the data limit results in a data overage fee of $10 for every 50 GB. 

On the contrary, Optimum offers unlimited data on all its cable and fiber internet plans.  However, you may experience speed throttling in the case of excessive data usage every month. 

Perks – Optimum vs AT&T Internet  

AT&T and Optimum both offer exciting perks.

AT&T offers up to $150 on reward cards for online order placements. New fiber internet customers also get an expert installation fee waiver ($99 in value) along with free ActiveArmor security ($7/mo. in value) and extended Wi-Fi coverage ($10/mo. in value).

AT&T’s Contract Buyout offer reimburses new customers for any termination fees or device payoffs they owe to their previous provider.

In addition to cost-saving bundles, Optimum gives new customers a Visa Prepaid Card with $100 to $200 in credits. Optimum Internet + Mobile customers also get a 60-day money-back guarantee. 

Installation Options – Optimum vs AT&T

AT&T and Optimum offer free self and professional installation options to new customers. Although Optimum’s standard expert installation costs $100, this fee is waived on online orders.

Similarly, the professional installation fee for AT&T Internet is $99. However, new customers get a fee waiver when they order the service online. 

If you want to self-install AT&T Internet, a DIY kit will be provided for free. The box includes a manual with step-by-step instructions for users who are not tech-savvy. 

Better Option for Gaming – Optimum or AT&T?  

Optimum and AT&T offer hyperfast and mirrored speeds on their 100% fiber-rich plans. However, latency and jitter matter more than speeds for top gaming performance. Luckily, fiber internet connections have the lowest latency rate and minimal jitter.  

AT&T Fiber offers latency between 7 and 13 milliseconds (ms). Whereas, Optimum Fiber’s latency rate is close to 14 ms. Moreover, Optimum’s fiber footprint is not even 1/4th of AT&T’s. So, the likelihood of getting superfast symmetrical speeds and ultra-low latency is slim. If the choice narrows down to AT&T Fiber and Optimum cable internet, always go with fiber. 

Wider Coverage Area – Optimum or AT&T?   

AT&T and Optimum are available in more than 20 U.S. states. However, AT&T’s availability is wider, covering 25 states in the North Central, South, and West regions. 

In contrast, Optimum availability is limited to 21 states, primarily in the South, Northeast, and Mid-Atlantic regions. 

It is mostly in the south of the country that Optimum and AT&T’s coverage overlap. The following are the 15 states where AT&T and Optimum offer high-speed internet service.

Better Customer Service – Optimum or AT&T?  

AT&T is one of the largest and most widely available internet service providers with top-notch customer support. It regularly ranks at the top in the two most trusted customer satisfaction surveys – J.D. Power and the American Customer Satisfaction Index (ACSI).  

From the tables below, it can be seen that AT&T’s customer service excellence is no match for Optimum’s below-average customer care. On both the indices, AT&T has topped the charts with above-average scores. Whereas, Optimum has scored the lowest points.

Final Verdict – Is Optimum Better than AT&T?

AT&T and Optimum are similar if you analyze their fiber internet service. Both offer superfast multigigabit speeds at affordable rates (for the first 12 months), with unlimited data, advanced equipment, and no-contract service. 

But when we consider their coverage and customer service, AT&T wins the race. AT&T is perhaps the only internet provider in the USA that offers fiber internet in more states compared to its non-fiber (IPBB) network. Similarly, AT&T has bagged the top positions for customer satisfaction in both fiber and non-fiber categories. 

Although Optimum is faster than AT&T, delivering equal upload and download speeds of up to 8 Gigs, its limited coverage area makes these speeds unavailable to many. Moreover, its poor customer service scores mean that if you encounter a problem, most probably it will not be resolved timely. So, in an Optimum vs. AT&T debate, always go with AT&T, the one the nation has declared the best.
