Notes

• * Eligible to customers applied to an eligible service or rate plan at the end of a month. However, customers whose rate plan will change to the au Adjust Plan from the following month are not eligible. Furthermore, depending on the period in which an application for a change of rate plan, etc., is made, application of Data Carryover may be from the following month.
• * If using Data Share, an eligible Flat-rate Data service or rate plan needs to be applied to all the lines to which Data Share is set. For customers who are setting Data Share with LTE Data Prepaid, carryover is eligible if an eligible plan is applied to a line that is not an LTE Data Prepaid line.
• * Only the monthly data amount that is set for each Flat-rate Data service and rate plan is eligible for carryover. An extra data amount that is provided with a campaign or other service, data amount that is carried over from the previous month, and data amount that is purchased with Data Charge are not eligible for carryover.
