When using Unlimited Calling with the aim of gaining direct income from communications through communication mediation, use of the forwarding function or connecting to a service provided by another company.
When using Unlimited Calling for purposes other than voice calls.

* Numbers that are specified by KDDI (such as the ones that are connected when using a telephone service provided by a carrier other than KDDI, and the ones that are continuously connected for a specified period for long-term or multiple communications due to a call that originates by a mechanical nature) are not eligible for flat-rate calls.

[Regulations of 4G LTE communication speed]

If the total amount of communications of the month exceeds the data quantity for that month (2 GB for Two-step data flat(Mobile phone)), the maximum communication speed for sending until the end of that month will be 128 kbps. (The communication speed restriction will be removed on the first day of the following month.) If you apply for the Extra Option, the communications speed restriction does not apply. Data quantities purchased with Data Charge can be used without any communications speed restriction.

Extra Option

To avoid network congestion, a limit will be placed on the communications speed for a whole day if you have used more than 6GB over the three most recent days (not including the day on which the restriction is applied). The restricted speed will differ depending on data traffic conditions. The constraint applies regardless of the remaining data amount.
Regardless of whether you are subscribed to a Flat-rate Data service, your line may be temporarily suspended if the cost of the packet communications you use becomes high.

[Communication amount notification]

Customers are notified via SMS (C mail) when the remaining amount of their monthly data amount drops below 10% or reaches 0% during the current month.

Customers whose total monthly data quantity and purchased data quantity for a given month is 5%,1% or lower will be notified by email to the mail address registered to the au ID.

*The actual amount charged is calculated using the tax amount calculated from the total amount of the individual tax-excluded charges, and therefore may differ from the total of the individual tax-included charges.
