This explanation covers billing plans for measured-rate FOMA data communications.
When using high-speed packet communications, only the packet communications charges according to the billing plan you have subscribed to can be applied to bills. When using 64K data communications, also, only the digital communications charges according to the billing plan you have subscribed to can be applied to bills. (ISP service charges are not included with either form of data communications.)
This plan is for subscribers who use data communications with PCs or other devices.

Cancellation charges do not apply if you subscribe to Flat-Rate Data Discount, Fami-wari MAX50, Hitoridemo Discount 50, Office-wari MAX50, New Ichinen Discount, or Ichinen Discount and change your billing plan to Flat-Rate Data Plan 64K or a measured-rate data plan. However, cancellation charges will apply if, during the subscription period, you cancel or suspend your line or change to a billing plan other than Flat-Rate Data Plan 64K or a measured-rate data plan (unless applying for Flat-Rate Data Discount, Fami-wari MAX50, Hitoridemo Discount 50, or Office-wari MAX50 at the same time).
Cancellation charges will apply if you subscribe to Fami-wari MAX50, Hitoridemo Discount 50, Office-wari MAX50, New Ichinen Discount, or Ichinen Discount and change your billing plan to Flat-Rate Data Plan HIGH-SPEED (unless applying for Flat-Rate Data Discount at the same time).
If you change between FOMA Data Communications Billing Plans in the middle of the month, free packets that remain will be calculated on a per-diem basis and carried over to the new plan upon conversion to a communications allowance monetary amount.
Two-month CarryOver of packet communications allowances for FOMA Data Communications Billing Plans cannot be shared even within Family Discount or Office Discount group.
You can sign up for Yu Yu Call at the same time as a FOMA Data Communications Billing Plan, but the discount will only apply to digital communications for Videophone. The bonus (communications allowances given to the called party) will not be available. You can receive the bonus from the other party, but the bonus will not apply for communications allowances the FOMA Data Communications Billing Plan applies to (received bonuses will be shown on your monthly mobile phone bill).
A ¥1,000 (¥1,050 incl. tax) handling fee will be applied each time from the third change to your billing plan between FOMA Data Communications Billing Plans (including cancellations and new applications) in the same month.
A ¥2,000 (¥2,100 incl. tax) handling fee will be applied each time to change between FOMA New Billing Plans or old FOMA billing plans and FOMA Data Communications Billing Plans.
When you change between FOMA New Billing Plans or old FOMA billing plans and FOMA Data Communications Billing Plans, the communications allowances (free packets) available for use with your billing plan before the change are not available and cannot be carried over to the plan after the change.
When FOMA Data Communications Billing Plans
1 and New Billing Plans are used concurrently in the same month due to changes in the billing plans, FOMA Data Communications Billing Plan packet communications allowances apply to FOMA Data Communications Billing Plan usage. New Billing Plan communications allowances apply for usage under New Billing Plans. In those cases, the amounts of unused FOMA Data Communications Billing Plan packet communications allowances and unused New Billing Plan communications allowances will not be appropriated to each other.
Also, Two-Month CarryOver will only apply to the free packets or communications allowances of the billing plan in use at the end of the month (FOMA Data Communications Billing Plan or New Billing Plan). If signing up for Family Discount, Two-Month CarryOver will not apply.
1 Data Plans here refers to Data Plan SS, Data Plan S Packet Plus, Data Plan M Packet Plus, Data Plan L Packet Plus, and Data Plan LL Packet Plus.
Please make use of the FOMA Byte Counter
Charges may be high when using packet communications for communications involving large amounts of data.
You can see how much data you have transmitted using the FOMA Byte Counter PC software which allows you to check how many bytes of data you have sent and received by packet communications and an estimate of charges for worry-free data communications.
