[About the Senior Plan]

  • * This plan cannot be used with models other than eligible models. Also, this plan is not eligible for the Student Discount or the Extra Option.
  • * When applying at the time of making a new subscription or switching models, this plan becomes applicable from the date of subscription or the date of switching models. Charges are prorated in cases where you cancel a contract before the end of a month.If you are subscribed to 2-year contract (Everybody Discount) and cancel Senior Plan , calculation on a prorated basis is not applied and the flat rate is incurred.
  • * For calls that straddle the 9:00 pm or 1:00 am time designations, charges are waived for the time segment straddling the time designation (30 seconds). Calls to special numbers including the Answering Service (Voice Mail) (1417) do not count as free calls. If KDDI determines that your call is continually long or it is affecting other calls, we may disconnect that call.
  • [2] [Restriction of 4G LTE/3G communication speed]
    • * If the total amount of communication exceeds the monthly data amount, the maximum communication speed for sending and receiving 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.)
    • * To avoid network congestion, a limit may be placed on the communication 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).
    • * Regardless of whether you are subscribed to a data (packet) flat-rate service, your line may be temporarily suspended if the cost of the packet communications you use becomes high.
