What are the hours and when should I call?
Optimum operates the call center for this 888-276-5255 phone number Mon-Fri 9am-5pm, Sat 9am-1pm ET.The short answer is that you should call on a Monday.This observation and the following section are based on analysis of a sample set of 1,299 calls made in the last 90 days using our free, web-based phone (see above).
Call when they- and you- are open
When you use our free AI-powered phone to call and talk, wait on hold, or navigate for you, you can also schedule the call with Optimum at a time when they are open and when it works for you. We will confirm you are ready before placing the call, just in case. That means you can "set it and forget it" ahead of time.
An important note: busy times vs hold times vs best time to call
When we refer to busy or less busy times, we are talking about the volume of calls. The busiest times are when the most people are calling this Optimum phone number (least busy times have fewer people calling). This high call volume does not necessarily mean that you will have a long hold time when you call. Companies like Optimum staff their call centers differently based on the time of day and day of the week, so you may experience a shorter wait on hold at the busiest of times. When we refer to the best time to call, we are referring to the optimal combination of lower call volume and shorter wait times.
The least busy time to call
The least busy day to call Optimum is Saturday.The most busy day to call is Tuesday, which averages 465% more phone calls by comparison.Again, this is based on a sample of 1,299 calls made with our AI-powered, web-based phone in the last 90 days.

The shortest wait on hold
We measured the shortest hold times to be on Monday.The longest wait in the queue on average occurs on Tuesday, which is 419% longer than the minimum.Most companies see more fluctuation in the length of hold times, but as you can see, time spent waiting for a Optimum representative is more consistent than the number of calls throughout the week.
In summation, the best day to call Optimum is Monday.It isn't the least busy day, but the fact that hold times are shortest combined with it being on the busy side tells us that Optimum staffs up on Monday to handle the higher call volume, and that makes it the best time to call.
Since my move to Ohio, I haven't had internet because I've been too busy to sit down and investigate my options. I had a major internet carrier before my move and it was far too expensive, so this time I thought I would look for a smaller company to hopefully help cut down my costs. For that reason, I wanted to chexk out Optimum which I heard piggybacks off a major carrier but offers more affordable plans. With that in mind, I figured the easiest way to sign up was just to call.
I was hoping this wouldn't take me too long, since you can easily spend forever waiting to talk to someone at an internet company. Between outages and billing questions, and then business clients, there are a lot of reasons why people could be calling Optimum. In fact, it turns out that Optimum's 888-276-5255 phone number went straight to its business service department, but I was able to choose residential service, so it all worked anyway. Unfortunately, Optimum wasn't an option for my address, but for anyone else, this line will help you sign up for internet even if you aren't calling about business service.
When I called, an automated voice answered the phone call and said, "Thank you for calling Optimum Business. To get started, please enter or say the 10-digit phone number that is on your account. You can also say, use my account number. You can also say, become a customer." Obviously, I didn't have a number linked to an account, so I just said that I wanted to become a customer. The next question was whether I was a home or business customer. I chose home, and then it asked me for the Zip code where I would like to have service.
It told me that, unfortunately, Optimum doesn't offer service in my area yet, but to hold because it does have a partner that offers internet service to my Zip code. That was a little disappointing, but I figured that the partner company would be about the same if Optimum was referring me straight to it. I was transferred to the SmartMove customer service line where I had to answer similar questions before a customer service agent picked up. It took me about five minutes to talk to someone there.
I'd recommend calling this line to anyone because it seems that even if Optimum can't offer service to you, it can find another company that can. That's more helpful than attempting to figure it out on your own.

Information about why customers call Optimum is extracted from issues that customers have reported to GetHuman.
If phone-based customer service is not available, or the wait times are long, many people prefer chat as a next-best option. Some even prefer it to calling on the phone. Luckily, Optimum provides this option.
Optimum, like many companies, provides customer service on the X platform (formerly Twitter). While it rarely entails live dialogue with a customer service rep, this channel can yield rapid response times and can be a useful option if you have an X/Twitter account.
As a last, sometimes only, resort- Optimum customer service can be accessed through their website. This can entail digging through help articles before finding a form and "being allowed" to submit a problem to their team, and rarely leads to a real-time conversation, which is why GetHuman does not recommend this unless it's the only way.
