I switched to Optimum Mobile in hopes… to save a few dollars. I switched to Optimum Mobile in hopes of saving a few dollars as I'm on a fixed income and my internet/phone service had increased by $22/month. They gave me a $5 discount per month on my internet/phone if I took their $25/month mobile plan as opposed to AT&T $65/month. It wasn't even a full week and already they were sending me text messages to up my service for more money. When I inquired about these text messages the agent stated those were only suggestions and that nothing would happen with my service. Today my service tanked and I have nearly ZERO bandwidth using the mobile data. BACK TO AT&T...!

WORST EVER WORST EVER! Coverage was not great and the number of times they had “issues” leaving me without a phone (once for 3 days!) were waaaay too many. The worst part was that after I cancelled them they continued to take $ from my account for two months! When I tried to get a refund I was told that they only give “account credit” refunds which of course was worthless to me DONT give this company your bank info!!!!

Unable to set up visual voice mail Unable to set up visual voice mail. Went to Optimum Store, said they couldn't help cal *611 for help which didn't work so I went to online chat for 2 1/2 hours still no visual voice mail. Was going to switch our other phones from Verizon. Not switching after such terrible customer service.

Little regard for customer of 22 years Terrible customer servcie, new customers are offered $35 per month, yet as a customer of 22 years, I cannot get this rate. While I did get a discount from $117 month fot $97, it is a far cry from internet service (have it and it is working great) that is faster and half the price. Now on the phone with customer service and waiting 30 minutes on hold to cancel -- really! Hope this message is read by Optimum management team to realize that this level of service can only have a negative impact on your business. So many other terrible reviews!

Internet goes out every time it is… Internet goes out every time it is cold. When calling their non-existent "customer service", only advice is to restart the modem, which I already did 10 times, and which does nothing. The third time, they finally made a service appointment...in 7 days. That did it. after 3 years of suffering from slow, unreliable service (1G is really about 150 MBs), switched to a slightly more expensive fiberoptic competitor, installed in 2 days. Finally, useable internet...something Optimum will not provide. Optimum is a racket, class action needed.
