What impacts data usage

All downloaded and uploaded data delivered over your Cox Internet service counts towards your data plan. There are two main factors that contribute to your monthly data usage.

Internet - Broken Circle %

Your activity

How you use your Internet impacts your data. For example, streaming an hour of content uses more data than an hour of checking emails.


Internet - Laptop 3 bulleted

Your devices

The number of Internet connected devices and the number of people using these devices in your household also impacts data usage.  When you have more devices connected to the same network, more data is going to be used.

Data usage FAQs

Have more questions about using your data? Here are some answers:  

If you go over your 1.25 TB of data, don’t worry. 50 GB of data will be automatically added to your plan for $10 on your next bill. 50 GB is enough to stream 15 hours of HD video. If you end up using that 50 GB, we’ll add another 50 GB for $10. We’ll keep adding 50 GB for $10 until you reach your $100 limit on data overage charges or until your next usage cycle begins.

If it’s your first month going over, you’ll get a one-time, courtesy credit for each $10 charge on your next bill.

Gigablast and Ultimate Internet tiers come with 1.25 TB (1,280 GB) of data. If you feel you need more data than 1.25 TB, you can add the Unlimited Additional Data Plan.

Yes. All of our residential Internet plans include 1.25 TB (1,280 GB) of data. This data comes at no additional cost.

Yes. Most Internet service providers (ISP) base their data plans around data usage.

Each month, your monthly usage cycle will start and end on the same dates. It’s worth noting that usage cycle dates are different than the dates on your bill. Additionally, these dates can be found on the data usage meter on the Cox app and on Cox.com.

Due to an increase in the number of people working from home and sheltering in place as a result of COVID-19, we have increased our data plan allowance by 25%. With 1.25 TB of data, we believe this amount is more than enough to cover extra usage. Check out the data usage calculator to pinpoint how much data you think you’ll need.

There are several ways you can keep track of your data usage. Cox.com offers a Data Usage Meter—which is also available on the Cox app. If you use the Cox app, you have the ability to add a miniature meter widget to your smartphone’s home screen. If you’re using Panoramic Wifi, you can use the Panoramic Wifi app to see which devices are using the most data in your household. Additionally, you can set notification preferences to alert you via SMS, email or browser when you reach 75%, 90%, 100% and 110% of your monthly data plan.

Check to make sure your email address and phone number are correct in the My Profile section of your account.
