Hi Parrothead, here is a link with some additional information regarding data usage,
www.cox.com/.../how-online-activities-impact-data-usage.html. As Chris previously stated, viruses and malware can increase your usage without your knowledge. Cox offers free virus protection, the Cox Security Suite. Streaming video typically accounts for the highest data usage. We would recommend checking the settings of what is being streamed. For instance, switching from 4K to HD or HD to standard definition. -Kevin M. Cox Support Forum Moderator
