  • The shown image is a sample. Items and amounts vary depending on the details of your contract.
You can see the usage period.
Since some service plans and optional services cannot apply pro-rated fee, we will charge extra fee according to the actual period of use of the change month.
For some discount services which cannot apply pro-rated discount amount, extra discounts only for the month will be applied according to the actual period of use of the change month. The extra discount will be shown separately on the itemized bill.
For "SoftBank Combined Payment", all settled amounts during the usage period of change month will be billed combined.
The amount of installment payments will never change.
For Internet services (SoftBank Hikari, SoftBank Air, etc.) and electricity/gas services bills that are combined with them, the bill for 2 months charges over the usage period will be added to the mobile phone service bill. (The bill details are shown separately by each month.) Note: Changing the billing cycle of SoftBank mobile phone services will never change the billing cycle for electricity and/or gas services combined with SoftBank service bill.

Notes on “SoftBank Combined Payment”

When using ”SoftBank Combined Payment”, an usage limit per each billing month is set for each service line account.
When the billing cycle changes, while the usage period will be longer as shown in the chart below, the usage limit will be raised during that period so that you will be able to use up to 100,000 yen in each month of April and May.
However, depending on the usage status during April, there may be temporary restrictions on usage in May. (*1)
The actual bill will be made as a combined bill for the May billing month.

  1. *1
    If you have manually set the monthly usage limit by yourself, the usage limit amount set by yourself may not be reflected on the change month. If you are going to use the pre-set amount, please double check the latest usage limit status on My SoftBank twice, once after May 1st and again after May 13th.
  2. *2
    The amount of usage limit varies depending on the customers' contract conditions and usage status. Please check My SoftBank for details.
