Cox Mobile Activation


As we walk you through activating your new line of service, you'll need access to the following items:

  • Your My Account profile username and password
  • Your Cox Mobile phone with a SIM card
    Note: The SIM card arrives within the Welcome Kit.
  • A computer or device that is not your new or old phone

Important: Before beginning the activation process, ensure your device has the latest operating system (OS or iOS). If this is not updated, errors may occur and the provider information may not update correctly.

Activating Your Device

The online activation portal guides you through activating your new Cox Mobile device.

  • You will select from the devices associated with your Cox Mobile account.
  • You cannot complete the online activation process from your new or old device.
  • Your devices can be identified by a nickname.
  • You must complete the activation process for each device.

Note: For assistance with guiding you through the activation portal or with issues, refer to Activating a Cox Mobile Device Using the Activation Portal or you can get more information from Getting Started which includes a short video.

Important: Leave the device powered off until you reach step four of the activation portal process.

Selecting a Phone Number

When you activate your phone, you are given the option to select a new phone number or port a phone number from a previous carrier. 

Type of Phone Number Details
Select a new number

With a new Cox Mobile phone number, you'll be able to select from a few different available numbers. These numbers have a local area code.

Port an existing phone number

We can assist you with porting your phone number from your previous carrier to Cox Mobile.

  • Your account with your previous carrier must be in good standing.
  • You’ll need the following information as it appears on the billing statement from your previous carrier. This information is commonly found on the carrier bill or from an online account. Refer to Locating Your Previous Carrier Account Information to view previous carrier information.
    • Account holder's first and last name
    • Billing address
    • Account PIN or password
    • Account number
    • Last four digits of the account holder's Social Security Number
  • We are unable to port toll-free numbers and pager numbers, such as numbers with 500, 800, 888, and 900 prefixes.

    Note: Activation times may vary when porting a phone number from another carrier.

Verifying Activation is Complete

Once your phone is activated, we recommend making sure everything looks right.

  • Look for Cox Mobile in the top left corner.
  • Restarting your phone initiates the ability to set up your voicemail. For device setup assistance, see Quickstart in  Setting Up Your Cox Mobile Voice Mail.
  • Make a call or send a text to confirm the phone is functioning correctly.
  • Download the Cox app to manage your account and devices.
