My question is why has my data usage jumped from 500 or 600 gig a month when I had Xfinity but now with COX I am using over 1024 gig a month and I have not changed how I use anything?

Hello, I am going to include some articles regarding how the Cox Internet Data Usage system works:

This article discusses how online activities can impact data usage, http://bit.ly/2KFZ0St. Please make sure that all of your devices are free of any malware or viruses. Viruses and Malware can use data without your knowledge. We also have a data usage calculator on our website as well, http://bit.ly/2MqUlD1. Lastly, our Data Usage Meter can be tracked with our Cox Connect app, http://bit.ly/2H3CHkz. -Kevin
