Optimum and Suddenlink

Suddenlink has become Optimum. If you previously had Suddenlink internet, TV, phone, or business service, your account support is generally handled through Optimum. Former Suddenlink customers may still see old references to Suddenlink email, equipment, account numbers, or service areas, but Optimum’s current support pages are the best starting point.

For legacy Suddenlink support information, see our related Suddenlink Customer Service page.

Before You Contact Optimum Customer Service

Have the following information ready before calling or chatting with Optimum support:

  • Your Optimum account number, if available
  • The service address connected to the account
  • The phone number or email address on the account
  • The service involved: internet, TV, home phone, mobile, business, or billing
  • Any modem, gateway, router, cable box, remote, mobile device, app, or phone error messages
  • Dates and times of outages, slow speeds, billing issues, missed appointments, or prior support contacts
  • A copy of the bill, payment confirmation, service agreement, order number, or disputed charge

Common Reasons Customers Contact Optimum

  • Internet outage or service interruption
  • Slow internet speed, weak Wi-Fi, modem, gateway, or router issues
  • TV service, cable box, DVR, remote, channel lineup, or Optimum Stream issues
  • Home phone, voicemail, robocall blocking, call forwarding, or phone-line support
  • Billing disputes, late fees, payment questions, or unexpected price changes
  • My Optimum login, password reset, app support, or online account help
  • Moving service to a new address
  • Canceling service or returning Optimum equipment
  • Optimum Mobile billing, device, SIM/eSIM, service, or international support

Internet Outage and Wi-Fi Support

If your Optimum internet is not working, first check whether the issue affects every device in your home or only one device. If multiple devices are offline, sign in to Optimum, use the outage page, check the My Optimum app, or contact support to see whether there is a known service interruption.

For slow Wi-Fi, record the time of day, affected rooms, device used, and speed-test results. A wired speed test can help determine whether the issue is the internet connection itself or the Wi-Fi signal inside your home.

TV, Cable Box, DVR, and Home Phone Support

For TV issues, note whether the problem affects all channels or only one channel, whether you see an error code, and whether internet service is also affected. For home phone problems, check whether voicemail, call history, robocall blocking, and calling features are affected before contacting support.

Billing, Payments, and Account Help

For billing questions, compare your current Optimum bill with your previous statement before calling. Price changes may involve taxes and fees, promotional discounts ending, equipment charges, late fees, mobile service, pay-per-view, service upgrades, returned payments, or partial-month charges.

Use the official Optimum website, My Optimum app, or account portal to view bills, make payments, manage automatic payments, and review account activity. Avoid entering payment information through unsolicited text messages, emails, pop-ups, or third-party sites claiming to represent Optimum.

Moving, Canceling, or Returning Equipment

If you are moving, contact Optimum before your move date to confirm service availability, installation timing, equipment requirements, and whether your plan or pricing will change.

If you are canceling service, ask Optimum to confirm the cancellation date, final bill, equipment return instructions, and any remaining device or service charges. Keep receipts, tracking numbers, confirmation emails, and photos of returned equipment. Unreturned equipment may result in replacement charges.

Optimum Business Support

Optimum Business customers should use the business support numbers for account questions, billing, technical support, internet, phone, TV, managed services, installation, or pending survey questions. Business customers should have the company name, service address, account number, contact person, affected service, and support ticket numbers ready before calling.
