Notes
[Unlimited Calling - Domestic flat-rate voice call service]
- [3]Flat-rate voice calls with this plan do not apply to voice calls to phone numbers starting with 0180, 0570 or other numbers that are charged by other carriers, voice calls to directory assistance (104), 1XY administration number services (188/189), SMS transmissions, voice calls to satellite phones/ship satellite phones, and voice calls to phone numbers that KDDI separately determines. Also, international calls and calls made to and from overseas are not applicable.
In addition, calls that fall under the following situations and all the other calls made from that line are not covered by flat-rate voice calls with this plan, nor are any discount call services applicable other than this plan.
- When using a mobile phone subscribed to this plan to connect to the customer's own communications equipment or to make an automatic call using software (except with the prior approval of KDDI in either case)
- 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
- *Should KDDI judge, for example, that a continuous call for a long period of time is affecting KDDI equipment, the call in question may be terminated
- *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.
[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 2-year contract or 2-year contract (No automatic renewal) the basic charge is prorated.).
- * Check for other costs arising from the contract at the store.
[Communication speed restrictions for 3G communications]
- * To avoid network congestion, a limit will be placed on communications speed for a whole day if you have used more than 3,000,000 packets 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. In addition, other restrictions, such as a maximum character length or attachment file size per EZweb email and a maximum daily data communication volume of EZ apps, are applied according to conditions for providing these services.
- * If packet communication charges reach a significant amount, phone lines may be temporarily suspended even if subscribed to the Flat-rate Data service.
