Overview of discount
- Family Discount takes effect from the day of application (applicable charges billed the following month). Discounts towards dialing and data communications charges take effect from the time of application. When cancelling Family Discount, discounts apply up to the end of the current month (applicable charges billed the following month). Some changes such as changes to the Family Discount group or to the designated landline phone number, may take effect the following month.
- If a number designated for Yu Yu Call is a phone number belonging to the Family Discount group, Yu Yu Call will be applied as the dialing charge discount. However, Family Discount will take priority when free dialing 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 in such a case.
- The discount amount for the basic monthly charge will be rounded to the nearest ¥10. If you cancel the discount during the month, the discount amount will be calculated on a per diem basis rounded up to the nearest yen.
- The discount amount for dialing charges will be calculated by multiplying the total monthly charges applicable for the discount by the discount rate. Discount amounts will be rounded up to the nearest yen.
- Communications allowances included in the basic monthly charges and communications that are applied to the Packet Pack monthly charges (=communications allowances) are also applicable for the discount for the dialing and data communications charges within the Family Discount group.
- With billing plans that include communications allowances, the communications allowance will not change after the basic monthly charge is discounted.
- Even if you change the service from mova to FOMA (except for the FOMA Ubiquitous Plan and FOMA Data Communications Billing Plans [flat rates]), you can continue using the Family Discount.
- Even if you change your subscription between mova, FOMA (except for the FOMA Ubiquitous Plan and FOMA Data Communications Billing Plan [flat rate]), and Xi, you can continue using the Family Discount.
- When subscribing to e-billing, the ¥105 discount off your bill will only apply to the main line of Family Discount, if the main line subscriber uses e-billing.
Payment of charges
- When payment is overdue by the subscriber responsible for paying monthly charges by single billing, all lines paid under the single billing group will be suspended if payment is not made after notice is sent to the subscriber responsible for paying by single billing.
- When the payment of the monthly charges of the subscriber of any line within the Family Discount group is overdue, Family Discount for that line or some or all lines within the Family Discount group may be cancelled.
docomo Points Service/docomo Premier Club
- When using payment by single billing for Family Discount, points are accumulated for the representative line and only the representative line subscriber is applicable to use the points. If a family member other than the representative line subscriber makes a request with consent from the representative line subscriber, that member is allowed to use the points accumulated for the representative line based on the request. Both main and sub-line subscribers are able to view the points accumulated for the representative line from i-mode. If a representative line subscriber wishes the points not to be displayed to or used by sub-line subscribers, an application will need to be submitted beforehand.
- If a subscriber other than the representative line subscriber wants to use the points, an application will need to be submitted beforehand with consent from the representative line subscriber. If advance consent from the representative line subscriber cannot be confirmed, a letter of attorney will need to be submitted, or DOCOMO may call the representative line subscriber to confirm consent by telephone.
- For those using individual billing with Family Discount, points will be accumulated individually for each phone line.
Sharing of Two-month CarryOver
- Unused communications allowances that remain after Two-month CarryOver is applied (which will become invalid if not used) will be applied to the usage in excess of the communications allowance for all lines within the group applicable for sharing. However, if an application for billing group sharing was made from the main line subscriber of Family Discount, sharing is limited to only within the same single billing group.
- All communications allowances to which Two-month CarryOver is applied can be shared (for example, communications allowances included in FOMA/mova billing plans, FOMA Packet Pack monthly charges, and Yu Yu Call bonuses).
- Unused communications allowances within the group applicable for sharing which will become invalid if not used will be divided in proportion to each line's usage in excess of the communications allowance. Furthermore, unused communications allowances will be invalid.
- All billing plans of the Xi/FOMA/mova service (except for FOMA Ubiquitous Plan, FOMA Data Communications Billing Plans [flat rate], and Xi data communications dedicated plans) are applied.
- Unused communications allowances that remain after Two-month CarryOver is applied can be shared and applied to charges incurred from the month Family Discount becomes applicable (applicable charges billed the following month). The following shows the cases of cancellation.
If Family Discount is cancelled, applicable amounts are shared and applied to charges up to the month of cancellation.
If mobile phone subscription is cancelled, applicable amounts are shared and applied to charges incurred up to the month prior to the month of cancellation.
- Billing group sharing becomes applicable from the charges for the month of application (charges billed the following month). If billing group sharing is discontinued, sharing within the single billing group will apply to charges up until the month prior to discontinuation (charges billed the current month), and sharing will apply to all lines within the Family Discount group from charges for the current month (charges billed the following month).
- The total amount of shared allowances will be shown in the monthly bill sent to the main line of Family Discount (representative line of single billing in the case of billing group sharing). The amount of shared allowances will be shown in the bill for each line to which the allowances were distributed.
- The amount of shared allowances is not included in the amount notified by Charge Notice Service and Billing Details Confirmation (for use in the current month).
- Sharing allowances with Two-Month CarryOver is not possible with Xi data communications dedicated plans, Flat-Rate Data Plan 64K, Flat-Rate Data Plan Standard, Flat-Rate Data Plan 64K Value, Flat-Rate Data Plan Standard Value, Data Plan SS, Data Plan S Packet Plus, Data Plan M Packet Plus, Data Plan L Packet Plus, Data Plan LL Packet Plus, Ubiquitous Plan S, or Ubiquitous Plan M.
Other notes
- When a subscriber wishes to have an itemized statement sent to the billing address and all charges for multiple lines under the Family Discount are billed on a single bill, the statement will be sent to the billing address of the Family Discount group subscriber responsible for paying the charges. If the mailing address for the Itemized Billing Service is to change as a result of applying for Family Discount, the signature and official identification of the Itemized Billing Service subscriber must be submitted with the application.
- When a sub-line subscriber subscribes to Itemized Billing Service and designates the address of the representative line subscriber as the address for receiving the breakdown of itemized charges, itemized billing statements will be sent to the address of the representative line subscriber if the representative line subscriber pays charges by single billing.
- Even if Family Discount has already been applied, DOCOMO may require the subscriber to present a document to prove the family relationship (health insurance card (that has not expired) or Certificate of Residence ([Juminhyo] [showing family relationship]) for confirmation.
- Even if Family Discount has already been applied, if DOCOMO discovers lines not applicable for the discount based on standards determined by DOCOMO, the line in question or all or part of the Family Discount group may have the discount cancelled.
