Optimum Anmeldelser 

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.

I’m extremely frustrated with my experience. I have made multiple payments on my account based on what representatives told me was required to restore my service, yet my service is still not reinstated.

Each time I speak with someone, I get a different answer. There has been no clear explanation of the exact amount needed, and no accountability for the misinformation I’ve been given. I’ve essentially been asked to keep making payments without any guarantee that my service will actually be restored.

At this point, it feels like I’m being misled into paying without resolution. If your account is in a “manual disconnect” status, be very careful—because payments alone may not restore your service, and this is not clearly communicated.

I would strongly advise others to get everything in writing before making any payments. Ask for the exact amount required for same-day restoration and a reference number for every interaction.

This situation has caused unnecessary stress during an already difficult time. I am still waiting for a clear, honest resolution.

After being a optimum internet customer that always paid my bill on time and endured 5 years of poor service before finally getting fed up and canceling service after extreme pressure from the retention department, optimum decided to place a errorous charge of $192.00 for a mobile phone i never received or agreed to. Five years ago optimum reps tried unsuccessfully to sell me a bundle including a free phone which I never agreed to. Keep in mind, this was five years ago. I had no idea this still existed, I never received a bill or account or phone from optimum. Now,this charge has dragged down my excellent credit score. Shame on Optimum for seemingly trying to punish me for canceling by creating a fraudulent charge from five years ago to strong arm me into paying a collection agency $192.00 that I don't owe. I know optimum is struggling to keep customers due to poor service and incompetent workers but to stoop to this level is a new low even for optimum. I have filed a formal complaint with FCC to resolve this issue and have this charge completely and permanently removed.
Please stay away from optimum they don't know the meaning of integrity and honesty. How sad. Shame on optimum, I hope they go under. Horrible organization.

Very unreliable internet. I have very important call to take and within the first minute boom the internet goes down. It happens every day but it was particularly frustrating to happen during something important. I cancelled the service the next day, they do not have prorated options like the rest of the world. Lastly, their inefficiency to address an issue. I had requested to bring down the internet service, they said I need to return the equipment at their store which I did but few months later they came back saying I didn't return the equipment and there is due with penalties. I raised a compliant in February and still there is no response except the messages where I am threatened that it will be sent to collections. I am making my preparation to raise a compliant in consumer court. Luckily I have all the conversations screenshot and the receipt of returned equipment.

The worst custom service ever!!! I tried working with them for over a year, it just got worst and worst. I've been trying to cancel my service for over a month, with no end in site. They do not care about the customers. I wish we could get neg star reviews, i would give them -5 stars.

The absolute WORST! We have been long-time customers on the cable/internet side of the house. When we told the cellular customer service “manager” that the rising cost of the cell service was going to lead us to drop all Optimum services, he replied with “That’s cool…here’s how much you’ll owe us for the phone.” The internet side of the business has amazing customer service. Optimum, you’re being negatively impacted by the so-called customer service of the cellular business. If you’re going to continue common branding, you need to get your cellular house in order!

I recently visited the Optimum store in East Hanover to replace my modem, and the experience was poor from start to finish. The salesperson was unfriendly and left me standing for 10 minutes while they struggled with their system—not once offering a seat.

I requested a new modem, but the associate also handed me a range extender without explaining it was an additional, paid service. I assumed this was a courtesy for a long-term customer, only to find a $10 monthly fee and a $5 one-time charge on my account later. This is a deceptive sales practice.

To make matters worse, the "new" modem had zero indicator lights working once I got it home. It clearly wasn't new or even properly refurbished; it felt like a direct return from another customer that was never inspected. It’s a hygiene and quality risk—you have no idea where this equipment has been. Check your account and your hardware carefully before leaving this store.

If there was a zero I would have give them that. I have been a customer of Optimum for 4 years. I am moving to SC and called to cancel my service. There is no way to cancel online and you have to call. I got a representative who insisted I give her my new address. She said it was required. I said I would not. Then she proceeded to tell me they require it and I said I just want to cancel. She kept at it and I told her I was losing my patience and I just want to cancel at the end of the billing period. She hung up! I called back and found out that she canceled the service at the end of the period. Rude and wasted my time.

We were told by the representative on March 10th to pay $132.04. Now being told that was incorrect and now we have to pay late fees. The representative today can’t see the text I was sent so I am posting here. As a service manager, I stand behind what my employees write, whether that be text, chat or email. Optimum should do the same instead of the standard “lip service” response you get here.

One star, only because it will not let you write unless you give it a star I'll start by saying that this company has to be the biggest worst provider in the world, and talking to them makes you feel like a real fool instead of listening to your problem and then analyzing it, they start with the basic unplug this and wait, now they are the first to tell you it will take about 5 minutes to reboot yet two minutes into the process they will ask you anything yet, come on give me a break after that you are told that you are having trouble with your internet, well guess what you're the provider of internet so as far as I can see you have no idea of what's happening to begin with and if you don't have any idea of what the problem is how the hell can you help anyone with anything, just once try putting yourself in the customers shoes and then maybe just maybe you'll help someone and who knows it will make you feel good about doing your job better, I know that anything that anyone writes or expresses with fall on deaf ears and that my friend is the PROBLEM WITH THIS COMPANY.

They are not capable to provide the services you pay for. Less than a month after internet installation my service went down and they have to send someone out. Today is Thursday and the soonest they can send so.eone out is Tuesday but I am SUPPOSEDLY VIP. I canceled my television service and downgraded my speed. I am not paying 175 a month for services I am not receiving!

I had an extremely frustrating experience trying to cancel my service with Optimum.

I called to schedule a cancellation at the end of my lease and was repeatedly pushed into retention offers that were never presented when I previously asked to lower my bill. While that was already disappointing, the real issue was that the representative canceled my service effective April 7th without my authorization or confirmation.

Now I have to call back and spend more time fixing an error that should never have happened. It’s incredibly frustrating to have your account changed without consent, especially when you’re already in the process of moving.

The lack of transparency, inconsistent pricing, and poor handling of my account made this a really negative experience.

I wish to have my service disconnected on the 4th of April. The guy says- oh no, you can’t turn it off until April 30 and you will have to pay your bill again and then the extra days too. I said no I will not pay it. The bill is in my deceased husband’s name. And my billing cycle ended 2 days ago. If I owed 4 days until it was disconnected I wouldn’t care but I’m not paying any bill and in own my own equipment and in leaning the state! So screw your optimum! This is the most ridiculous situation to outright stealing and price gouging! I’m going to the ftc!

Consumer Reports rates as one of the worst internet services in the U.S.

Internet speed promised never worked
Constant outages
Pathetic customer service
When you want to stop your service, it takes multiple calls and hours of your time. Document all conversations as you will be going back and forth with different people/departments.

No consistent policy. NEVER SIGN UP for Optimum service.

Optimum Mobile: An Absolute Disgrace of Customer Service
I have never in my life experienced a more infuriating, incompetent, and utterly useless customer service operation. Getting a live human being on the phone is nearly impossible, and when you finally do, the communication barrier makes it impossible to get a straight answer. Instead of actually helping, they either transfer you in circles or simply hang up on you — as if your problem never existed.
I called with a straightforward question about my text message usage. What I got was completely fabricated data — the same number repeated over and over, clearly not reflecting my actual usage. This isn't a minor error. This is a company feeding its customers false information about their own account.
Then, to add insult to injury, a representative actually called me back — not to fix the problem, but to inform me that they cannot provide accurate records. Meanwhile, I had another Optimum representative on a separate line who was able to pull the real numbers without any issue. So not only are they incompetent, they are inconsistent and contradicting their own staff.
This company has zero accountability, zero competence, and absolutely zero respect for its customers. Do yourself a favor — run as far away from Optimum Mobile as possible.
