[Flat-rate Data]

• * For Two-step data flat Z(Mobile phone) and Two-step data flat Z(Mobile phone), data communications charges from overseas use are not eligible to be included in the fixed rate of the Flat-rate Data service. Two-step data flat for Overseas can only be applied when you are automatically connected to an eligible carrier.
• * For Flat-rate Data 2 (Mobile phone), 3 (Mobile phone), and 5 (Mobile phone) users, when World Flat-rate Data is used overseas, the communications charge consumes the monthly data amount of the domestic Flat-rate Data service.

[Application of Charges]

• If applying when making a new subscription or switching models, the rate plan and Flat-rate Data service become applicable from the date of subscription or the date of switching models (the basic charge is prorated). If changing the contract, it becomes applicable from the month following the month of the change. If changing the contract or switching to a model you bring to a shop, the service becomes applicable from the month following the month of the change or switch. If you cancel in the middle of a month, the rate plan and Flat-rate Data service charges are not prorated and the flat rate is incurred (If not subscribed to Everybody Discount or Everybody Discount Light, the basic charge is prorated.).
• Check for other costs arising from the contract at the store.

[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.

• 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]
