Optimum Reviews 

I signed up for their mobile phone service on March 3, 26. The line was not activated for 19 days. I transferred my wife's phone following their instructions and she was without service for 6 days. 25 phone calls to their customer service team and nothing was resolved. To cancel everything was more painful then having an arm amputated with a rusty saw. I had to demand 22 times that my account be canceled, and yet they are still charging me for a line and service I don't have. Next stop is legal action

I wish there was an option to give lower than one star. I live in Leander Texas and we're pretty much stuck with them if we want unlimited internet. They are hot trash. Straight up hot trash worse internet ever goes out at least 2 to 3 times a week.

Virtually impossible to cancel service. When you call they put you on hold and verify your info dozens of times and eventually they just hang up. I'm paying nearly $200 a month for service which is 1000 miles from where I now live and I'm stuck with it . Not a thing I can do . I've called about 11 times trying to cancel.

They kept raising my internet price by $10 every month for no reason without telling me so I tried to cancel my plan. When I called, they initially had me on hold for 30 minutes, then forwarded me to four different agents who all claimed they would cancel it. I had to explain to each one them my situation every single time which was very repetitive and they didn't help whatsoever. On top of that, each of them kept offering to discount my rate by $20 if i kept the plan. I kept declining and said I needed to be somewhere important soon but they didn't listen and kept on going. Finally, after over hours they said they cancelled my plan. The crazy thing? When I checked again the next day my plan wasn't even cancelled. The absolute worst customer service I've experienced in my life

I wish I could give 0 stars to them. They lie and give you service then they charge you for what you didn't even know. RUN AWAY FROM THEM AND SAVE YOUR PRECIOUS TIME, HEALTH, HAPPINESS, PEACE OF MIND.

We were replacing our internet boxes and while there, the representative convinced me to switch to Optimum Mobile. His name is Daulin Pena at the Morristown store. He went out of his way to explain everything about the service and that it would be less expensive than the Verizon service I had. A lovely young man.

I have absolutely never done business with a company so awful. The way that you manipulate vulnerable people and force services with promises that are lies is despicable. It is only a matter of time before you face your consequences. Sickening. and if you are a young person working for these criminals . GET OUT! I am amaaaaazed at how many horrible reviews with the same story are posted everywhere and you still are authorized to run a business.

Worst internet service ever. Paying for services we never received. Then when you call to cancel they try to upgrade you for more services that you will not receive. Constantly getting text saying no service and d not know when you will have it back, but you will still need to pay your monthly bill. Had service for 10 days out of 30 but still required to pay a full month for the service. Of, when you call to cancel the service, it is like getting a government office to do some work. I am having tk beg and plead with them to cancel out my service. I am not even hooked up to anything with them now and they still will not cancel.my service. STAY AWAY FROM THIS COMPANY, BAD BAD BAD. Even when you are dead, you will have service with them because they refuse to cancel. Clingers, you can't break up with them

My area doesn’t have fiber so there were outages at least 2-3 times a month. ATT has fiber so I went to Optimum website to cancel. No, you have to call to cancel.
Worst experience ever. They kept me on the phone 34 minutes!!!! They have a script they need to go through. She kept saying “I understand” and then continues on her script. Everything she said showed she didn’t understand that I simply wanted to cancel. After 31 minutes she said she has to transfer me to an account manger who offered lower price. When I interrupted to ask, “ Did the last person cancel my account? She said, “Don’t rush me”. Unbelievable. Finally after 34 minutes I got off with assurance that they would process cancellation.
Optimum if you had just done want I asked in a few minutes I would never have written this review but making your agents badger customers over and over is bad business- and I bet causes high turnover.

My most recent interactions I called got hung up on multiple times, was transferred and had to restart multiple times and to beat it all after finally thinking my address got updated and my username corrected as they input it incorrectly last time I called, well neither was ever corrected so today I contacted the chat on the app told her the problem and she stated I had to call and before doing so was trying to reset my password when I never requested it. Then she had the audacity to say she was going to disconnect the chat because of abusive language because I stated that changing from Suddenlink to Optimum has not helped their customer service. Again no assistance but to tell me I have to call a number where I have never been helped since I have been with this company even after the name change. I am disappointed that they call it customer service. I am a customer service agent for the State and yes we actually assist people. If you are paying these individuals as employees at least make sure they do their jobs. Look at the reviews, that alone should get the wheels moving to correct a bad situation and possibly allow your customers to feel like they were assisted. small things can do a lot but I would start with a better way of monitoring my agents and accountability. Otherwise the company will just change its name again to trick people into thinking things will get better

We have had Optimum service since it first became available on Long Island. It has generally functioned okay, but any dealings with customer service or tech service has been an absolute nightmare. Our most recent experience was especially challenging. We have moved to a different state and needed to cancel our service and return the equipment. I went to the Port Jeff Station location and they refused to accept the equipment back unless I called the Optimum number first. Four other people were in the same predicament that I was. They had in stand in the lobby and call the phone number. The person on the end of the line refused to cancel the service because it had my spouse as the primary person on the account. She kept asking for him to be put on the phone or call them himself even though I explained he was currently on an airplane. I asked to speak to a supervisor and they said there were none. After 30 min, I gave up. The Port Jeff location still refused to allow me to give them the router and cable box. (There was no supervisor there either and they said that person only works on Thursdays.) As a result, I had to bring the router and cable box to the state where I now live, spent another 30 min on the phone, and now I have to ship it back to NY. The customer service rep obviously had a script to follow because he kept offering special deals to keep my service no matter how many times I said I had moved and want nothing more to do with optimum. He was planning to send me the packing slip information to the optimum.net email address even though I would no longer have access to it! Once he finally processed the cancellation, he offered a special offer for mobile phone service. When the call finally reached it's end, I had to officially say that I wanted the service cancelled. Then he told me it would stop at the end of the billing period, so Optimum is charging me for 2 weeks of service that I'm not using -- a final way of overcharging and scamming customers.

They like to waste your time with their representatives.

This company lures you in with a good price and no contracts but if you have a problem you are at thier mercy. My modem would stop working anywhere from every 5 mins to 30 mins. I contacted the tech department and they sent me another modem. After several failed attempts of self set up I contacted the tech department again. They told a service tech would have to come on site to fix this issue and the soonest they could be out was 11 days from then. I then received a text msg asking if the issue was fixed. If not to respond with AGENT and I would get a call. The agent seemed to be having a problem with line cutting in and out, and hung up on me. This happened twice. Two days later I received an email to rate my experience. The next day I got a phone call from Optimum who told me I could go to a store 1/2 hour away to get another modem, and option that was never mentioned before. When at the store the representative told me in an apologetic tone that the company values new customer hook ups more then customers with issues and he himself could not get a field tech to his house for 2 weeks. This did not make me feel better. I was actually wondering why I was continuing to do business with this company. They just want to give their customers homework assignments to fix the companys issues. Their idea of customer service is to pass you off to someone else or see if they can ignore you and maybe you will go away. I finally got the problem with their faulty equipment that they gave me not two months earlier, with great effort on my part.

Optimum is a HORRIBLE I had no tv internet for part of April 15th and part of April 16th. I called them but it was very hard to get thru to them. When I finally got thru which was a number of times none of them knew what they were doing.Finally after hours of getting aggravated I finally got a woman who knew what she was doing and all was working fine after that till the next time. This happens every once in awhile. They know how to charge u the money but the service SUCKS.

I switched to Optimum Mobile in March 2026 and purchased an iPhone 16 and a Galaxy A26 on 36-month installment plans. Since day one, my iPhone has been unable to receive group text messages — MMS and RCS group chats simply do not deliver. Individual texts work fine, but any group thread is a black hole.

I have contacted Optimum support more than six times about this. I reset network settings, changed APN configurations per their instructions, deregistered from Google RCS on my old Android, and confirmed iMessage setup. Nothing worked. A manager I spoke to informed me that messaging is actually a feature of a phone and not necessarily their responsibility (despite group messaging being a basic function of any mobile service).

I'm now locked into over $1,000 in device payments with no ability to switch carriers — the return window has passed and their unlock policy requires 60 days of active service plus full device payoff. So I'm paying monthly for a service that doesn't deliver basic functionality, and Optimum has no interest in fixing it.

I'm missing family group chats and work group messages daily. If you're considering Optimum Mobile, know that their support will not help you if something fundamental doesn't work. I would not recommend this carrier to anyone.

If I did need to give it one star I would give it none. The Customer Service sucks and when I got a supposed Supervisor he was no help what so ever. They do not care about the customer just profit. I was with them for 16 years!! Their prices keep going up and using the service they continue to buffer when watching a program. That is why I left. I called last year to disconnect my service and the representive keep offering me insentives to stay which where not that great. I told him no I want to disconnect I have another provider. He said okay we will keep your account open for 6 months in case you want to come back that was July 2025. I just got a bill say I owe 165.00 for Feb and March but did not get notice they where going to start billing. I did not use the service I have service. I am not paying for service I did not use!! I requested that they write off or waive the balance as I did not use the service. He say it is legit and he refused to waived or write off the balance as a courtsey. That is what I get for 16 years of service. I work in customer service and collections and I as courtsey would have done just that. They won't be around long with representive like that. If I did not like my current service I would not even think about going back to Optium!!They are horrible and rude insensentive robots.

The customer service actually is clueless. I tried to put my account on seasonal hold which was supposed to be very simple and straight forward only for them to screw the whole thing up then tell me I couldnt do it when I actually needed it. 4 chat conversations and 1 long phone call later and I would rather just pay the stupid bill than work with their customer service. The internet is quite honestly great but the helpdesk is worthless.

Worst company terrible product and service but they have monopoly on Long Island. They should be shut down

I will never return to Optimum as a customer. Everything is geared towards profit and little towards customer service. After having dealt with the local Optimum store, off-shore customer service and Optimum's "Executive Customer Relations" it is clear this mentality is woven throughout the entire organization. I have experienced random increases in cost, misleading bills which change terminology from "Speed Credit" to "Internet Credit", adding a monthly charge for the router where there was no such thing prior to that, increasing my service from 300 Mbps to 500 Mbps without my request to do so, then charging a higher rate after the "introductory period" was over, as well as flat-out lies. And if you cancel service just one day into a billing cycle? No prorating, you'll get billed as if you received service for that entire month. Oh, they'll offer to credit your account if you will agree to restart service, but if you don't, you'll get charged.

horrible service took 2 days and hours on the phone trying to cancel cable and phone but keep internet. it was a scheme like trying to quit a GYM...they should have done this last week but they threw me out 24/7 support chat that ended at 9pm while the Rep seamus TRIED UPSELLING ME TO OPTIMUM MOBILE.. was very fun 3 weeks after my MOM'S DEATH. this shouldn't take over 2 F'IN HOURS.
