How calculations are made
- Communications made within the communications allowances included in basic monthly charges and the Packet Pack monthly charges (= communications allowances) are also eligible for Yu Yu Call Discount.
- Yu Yu Call Discount can be applied for in combination with Ikkatsu Discount and Volume Discount.
- If a number designated for Yu Yu Call Discount is a phone number belonging to the Family Discount group, Yu Yu Call Discount will be applied as the dialing charge discount. However, Family Discount will take priority when free voice communications charges or 60% off Videophone communications charges are applied to communications within the Family Discount group. It is therefore recommended to change numbers designated under Yu Yu Call Discount in such a case.
- The discount calculation period is one month (one billing month).
- The discount amount will be calculated by multiplying the total usage charges for the month applicable to the discount by the discount rate and will be rounded up to the nearest ¥1.
- Even if you change the service from mova to FOMA (except for the FOMA Ubiquitous Plan and FOMA Data Communications Billing Plan [flat rate]), you can continue using this service. Furthermore, if you change the service part way through a month, the total of that month's charges for the FOMA service (except for the FOMA Ubiquitous Plan and FOMA Data Communications Billing Plan [flat rate]) and mova service which are applicable for discount will apply.
- If a number designated for Yu Yu Call transfers to another mobile phone carrier, the discount for charges for calls after the transfer will be automatically determined and applied.
Applicability to international numbers
- Yu Yu Call Discount only applies to international numbers when international calls are made using WORLD CALL. It does not apply when another carrier's international calling service is used.
- Yu Yu Call Discount does not apply to charges for International SMS, International MMS, 64K digital communications, or WORLD WING.
Bonus
- Only the dialing charge discount applies if you subscribed to New Billing Plans, and the bonus (communications allowance given to the called party) does not apply. However, the bonus (communications allowance given to the called party) does apply when you receive an incoming call from a caller on a previous billing plan who has designated your number under the Yu Yu Call Discount. The bonus does not apply to calls received with a DOCOMO IP phone.
New applications for previous billing plans are no longer accepted as of October 31, 2005.
