How does the rolling 30 days work?
Your daily upload and download data usage is measured to determine if your total usage has exceeded either of your usage thresholds over the previous 30 days for the service plan that you have selected. A rolling 30 days is defined as “the past 30 days” from the current date. For example, if today were July 25, 2008, your usage would be measured from July 25, 2008 back to June 26, 2008. If you check your usage again on the next day, July 26th, your 30-day window would be from July 26 back to June 27. Note: The rolling 30 days is independent of the number of days in the month.
