Understanding speeds and data plans

Speeds: Downstream and upstream speeds as well as factors such as your in-home WiFi network and number of simultaneous users, can impact your Internet experience.


Data Plans: A Data Plan is the amount of data included within your monthly Internet package, measured in Gigabytes and Terabytes, as indicated in the footnotes below. Data Usage is the amount of data, or bandwidth, used from all of your online activities. The following Cox services or video content do not count toward your data usage.

  • Cox Digital Telephone service.
  • Most video content accessed from your cable receiver, the Contour app, and on watchtv.cox.com.

Playing video content identified as Internet or TV GO does count toward your data usage. The following icons display by each applicable program title.

  • In the Contour 2 on-screen guide, content marked with the icon will count toward your data usage.
  • In the Contour app and on watchtv.cox.com, content marked with the icon will count toward your data usage if your device is connected to your Cox Internet service.

Cox will attempt to notify you by email and SMS (depending on your notifications preferences) when you pass different usage thresholds starting at 50%, depending on where you are in the cycle of your Data Plan. If you use more data than is included in your plan, we will automatically add additional data for $10 per 50 Gigabyte (GB) block for that usage period and a charge of $10 will be reflected on your bill. Each time you need another 50 GB block, it will be automatically applied to your account and $10 will be added to your bill until you reach your $100 limit on data overage charges ($30 limit for ConnectAssist customers) or until your next usage cycle begins. Cox will credit you for the overage charges on your bill the first time you use more data than your data plan. You can always check your Data Usage by going to the Data Usage Meter located in Internet Tools. Please verify that we have the email address to which you prefer to receive email notification. Please visit my account profile and setting to update the email address in your profile.
 

All services and plans subject to Cox Residential Customer Service Agreement  (including mandatory arbitration provisions), Acceptable Use Policy (including Cox’s right to terminate service for abuse of network), and other policies.  
 

For more information on Data Usage, please see our Data Usage learning site.

Footnotes

  1. Data Plans: A Data Plan is the amount of data included within your monthly Internet package, measured in Gigabytes and Terabytes, as indicated above. Data Usage is the amount of data, or bandwidth, used from all of your online activities. The following Cox services or video content do not count toward your data usage.

    • Cox Digital Telephone service.
    • Most video content accessed from your cable receiver, the Contour app, and on watchtv.cox.com.
       

    Playing video content identified as Internet or TV GO does count toward your data usage. The following icons display by each applicable program title.
     

    • In the Contour 2 on-screen guide, content marked with the icon will count toward your data usage.
    • In the Contour app and on watchtv.cox.com, content marked with the icon will count toward your data usage if your device is connected to your Cox Internet service.

  2. Maximum Message Size: This is the largest email you can send or receive, including attachments and encoding. Not all ISPs may accept messages of this size. Email messages will not be sent or received if they exceed the maximum message size or if they would cause the storage limit on your mailbox to be exceeded.

  3. Dormant Mailbox Deleted: Any primary or secondary mailbox that is not checked for new email for at least 120 days following the last access by the user will be permanently deleted, and the contents will no longer be available. New messages sent to a mailbox that has been deleted will not be delivered. Customers will retain the right to the associated User ID as long as they remain a Cox customer in good standing and do not release the User ID. The Primary email account holder may reactivate dormant secondary mailboxes that have been deleted through Internet Tools, but may not reactivate mailboxes that have been deleted for inactivity as set forth above.

  4. Trash Folder Contents Deleted: Content in the Trash, Deleted Items, and/or any other folder where deleted messages are sent in Cox Webmail or on any other mail client may be deleted at any time and without notice. The Trash, Deleted Items, and similar folders are not message storage folders, and deleted messages are not retrievable. A message may be retained by downloading the message via POP-3 (like using Outlook Express) or moving it to a folder in Cox WebMail or the applicable mail client other than the Trash or Deleted Items folders (subject to mailbox size limits).

  5. Unread Message Retention in Inbox Folder: Messages that are marked as "unread" and remain in the Inbox for more than sixty (60) days are subject to deletion without notice. A message may be retained by downloading it via a POP-3 client (such as Outlook Express), moving it to an alternative folder in WebMail, or by marking it as "Read."

  6. Message Retention in Spam Folder: Messages that remain in the Spam folder for more than twenty-one (21) days after receipt are subject to deletion without notice. A message in the Spam Folder may be retained indefinitely only by moving it to an alternative folder in WebMail (subject to mailbox size limits).

  7. Email Account Message Sending Limits: To control automated spam messages, you may not send multiple messages beyond a limited number in an automated fashion (i.e., using a mass mailing client). Specific limits are not published because they vary from time to time depending on a variety of factors, but the limits are set such that a typical user should not be impacted. Cox uses other measures to control spam, including limiting the ability to send email from accounts that Cox believes are being abused, or have been compromised, for the purpose of sending spam. Again, typical users should not be impacted by these limits.

*Applies only to existing Cox email accounts. As of August 15, 2019, we will no longer offer Cox Internet customers the ability to create new Cox email accounts. This change does not impact existing Cox email accounts. We will continue to support email service for customers that have email accounts created before August 15, 2019.
