How to Cancel
Phone
Phone is the only option. Optimum doesn’t let you cancel online or in-person.
Call (833) 200-7514 and navigate to cancellation. You may be offered bundle packages, discounted rates, or free months of service. If you have made up your mind, keep the call focused on cancellation and final account details.
Before you hang up, get a confirmation number and ask for email verification. Write both down.
Optimum has regional numbers that may connect faster depending on your area:
- Bronx/Brooklyn/Westchester: (718) 860-3514
- New Jersey: (973) 230-6048
- Long Island: (631) 393-0637
- Connecticut: (203) 870-2583
Have your account number and billing cycle date ready before calling. If you’re not fully committed, ask about service suspension first - Optimum offers holds up to 6 months at (866) 218-3259 (reduced monthly fee applies).

What It Costs
Nothing beyond your regular bill. Optimum is month-to-month with no contracts, so there’s no early termination fee.
The one gotcha: if you signed up for a promotional rate and cancel before the promo period ends, Optimum may charge you the difference between what you paid and what the standard rate would have been. Check your promo terms before calling.
Optimum doesn’t prorate. If you cancel mid-cycle, you pay for the entire billing period with no partial refund. Your service stays active until the end of that cycle.
Equipment Return
What You Return
- Modems
- Routers
- Cable boxes and smart cards
- Digital antennas
- All remotes and power cords
If you own your own modem or router, you keep it. Only Optimum-provided equipment needs to go back.
How to Return It
FedEx - use Optimum’s FedEx return portal to generate a prepaid shipping label. Drop off your packaged equipment at a Walgreens, FedEx Office, or any authorized FedEx location. Get a receipt with tracking.
Deadline
30 days from cancellation. Return equipment as soon as you can.
Unreturned Equipment Fees
| Equipment | Fee |
|---|---|
| Cable Box / Smart Card | $180 |
| Modem | $100 |
| Router | $80 |
| Digital Antenna | $25 |
These add up fast if you had multiple devices. Photograph everything before you hand it over, note the serial numbers, and keep your receipt until the final bill comes clean.
After You Cancel
Final bill includes your monthly charge through the end of the billing cycle, plus any unreturned equipment fees or promo clawbacks. No surprises if you returned everything and timed the cancellation right.
Confirmation arrives by email within 24-48 hours. If it doesn’t show up, call back with the confirmation number you wrote down.
Reactivation is available, but don’t expect new-customer pricing unless you’ve been off Optimum for at least 30 days.
Suddenlink customers - if you were a Suddenlink customer before the rebrand, everything above applies to you. Same systems, same policies, same phone numbers.
Common Problems
| Problem | Solution |
|---|---|
| Long hold times on the main number | Try your regional number (listed above) - they often have shorter queues |
| Aggressive retention offers | Ask for the offer terms in writing if you are considering it; otherwise keep the call focused on cancellation. |
| No online or in-person cancellation | Phone is the only option. There’s no workaround |
| Equipment charges after return | Call immediately with your FedEx receipt and tracking number. |
| Full-month charge after canceling | Check the disconnect date against the billing-cycle cutoff. Optimum does not prorate, so timing controls the final month. |
| Promo clawback charge on final bill | Check your original promo terms. If the charge doesn’t match, dispute it with your confirmation number |
| FedEx drop box rejected equipment | Use a staffed location only - Walgreens, FedEx Office, or authorized FedEx retail. Reprint your label if needed |
