Known for its versatile range of products and reliable services, Optimum by Altice USA is the ideal internet service for homes and businesses. Optimum cable services are available to an estimated 12.9 million people in Connecticut, New Jersey, New York and Pennsylvania. Optimum also provides fiber optic broadband in select areas. And, about 1.8 million people are able to access its fiber service.

Optimum believes in making peoples’ lives simpler and more empowered—so it strives to make the fruits of innovative tech accessible for the American masses. Today, Optimum subscribers can benefit from high-speed internet that comes backed by a hybrid fiber-coaxial network. But, Optimum still keeps its price points affordable for most household budgets. Plus the provider does not restrict you with an annual contract.

However, any internet service needs a compatible model to work with it. And Optimum is no different. Even though internet providers routinely offer equipment of their own—on a rental basis or with an option to buy upfront at times—most ISPs do let you bring your own device(s). As a result, when your package expires, or you upgrade to a higher speed from the same or another service provider, chances are you won’t face the probability of paying a hefty modem rental fee. Your own up-to-date modem may be good to support higher speeds or run a different connection.  

So, for those looking forward to getting their hands on the Optimum services, it’s time to look for an Optimum compatible modem that would bring high-speed internet to your home.

An Overview of Optimum Internet Plans

Before we jump into the Optimum compatible modem list, let’s first take a quick look at what internet packages the provider offer does. So, for starters, know that you can use your Optimum internet service with any certified DOCSIS 3.0 modem. However, the quality, functionality, features and several other aspects must be taken into account when choosing the best compatible modem for Optimum Internet.

Optimum delivers a wide range of high speeds: In most service locations you come across a 300 Mbps internet package, which costs $39.99 month for 12 months. A 400 Mbps plan priced at $64.99 (For Life), and an impressive 1 Gig internet service that costs $69.99 a month (For Life), are also on the Optimum menu. Plus, there are several bundle options that include a combination of internet, cable TV and voice services. One such example is the Optimum Internet 300 Core TV package which comes priced at $74.99 for 24 months.

Why Do I Need to Buy a Modem with My Optimum Internet?

As we said earlier, like other ISPs, Optimum offers internet equipment with their packages. But that comes at a monthly rental fee. This arrangement is ideal for people who might have subscribed to the internet service for a short while. Or for those who are not the least tech savvy. But, for people planning to use the service for a longer period, or those who feel confident about troubleshooting problems on their own, it is cost-efficient to purchase their own device. You may have to invest some time and effort in finding the right one, but buying a modem for your Optimum internet package may be the wiser choice.

Let’s add a word of caution here though. Optimum provides 24/7 tech support to subscribers who use an Optimum-provided modem. And, the equipment is replaced if it malfunctions. When you BYOD, Optimum tech support, upgrade or replacement service is not applicable to your device.

A powerful modem compatible with your service provider plan is key to squeezing the most juice from your connection. The good news is there are several compatible modems for Optimum in the market—from trusted names in the industry. So, if you wish to save an estimated $100 a year in modem rental fee, go ahead and pick a budget option. 

Remember it is necessary that you know which speed tier would work for your digital needs, before you subscribe to an Optimum internet plan. It is easy to get tempted by higher speeds that you never would utilize.
