Check your Rollover Data

Learn how to check your Rollover Data balance. Plus, get details about how you collect and use it.

View your Rollover Data

If you didn’t use all your data last month, it’ll roll over to next month’s data allowance on your plan. To find out your Rollover Data® allowance:

  1. Go to the Usage center. Sign in, if asked.
  2. Look under the data usage graph and select View details for an in-depth view.

Keep in mind: Only Mobile Share Plus℠, Mobile Share Flex, Mobile Share Advantage, and Mobile Share Value® plans include Rollover Data. AT&T 4GB plan, Mobile Share, and Mobile Share data-only plans don’t include Rollover Data. 

Use Rollover Data

Each month when you don’t use all your data plan allowance, it’ll roll over to next month. For example:

  • Your plan includes 9GB of data. You only use 4GB of data that month. 
  • The unused 5GB from that month becomes Rollover Data and is added to your available data for use next month. 
  • This means that you’ll have 14GB of data to use during the next month. 

You’ll start using Rollover Data only after you use all data included in your monthly plan and any other data allowances in a month. For example:

  • Your plan includes 9GB of data. 
  • You also have 5GB of Rollover Data to use from the previous month, for a total of 14GB.
  • You used 12GB of data this month, 9GB of plan data, and 3GB of Rollover Data. Your remaining 2GB of Rollover Data will expire at the end of the bill period.

FYI: Your Rollover Data expires after one bill period or with a plan change, like changing your plan’s data amount. You can’t:

  • Redeem unused Rollover Data for cash or credit.
  • Transfer your Rollover Data to others on your account.
  • Use Rollover Data for international data.
