[General information on au After Service]

  • Only "mobile phone devices" and "battery chargers" with a trademark of "au" or "iida" are eligible for au After Service.
  • "Battery chargers" means devices that can charge a mobile phone device such as an AC or DC adaptor.
  • If a product is modified, altered, analyzed (including altered software, analysis (including rooting), reverse engineering, decompiling, or disassembly) or it is repaired at a repair site that is not officially specified by KDDI, it may not be covered by the warranty or repair may be refused.
  • Note that using commercially-available non-genuine accessories other than au genuine parts may result in malfunction or failure.
  • Devices for which au cannot provide this service are not eligible for au After Service (Example: digital network devices or other devices)
  • Parts that are replaced in services such as "Three-year (One-year) warranty service", "Repair fee discount service", and "Renewal service for exposure to water and total damage" are collected and recycled by KDDI. They cannot be returned to the customers.
  • If there are multiple malfunctions, partial repair is not available. Partial repairs cannot ensure the product quality. For this reason, all of the malfunctions are repaired before retuning. (Depending on the items for repair, charges may be incurred.)
  • For inquiries, contact the Keitai Guarantee Service Center.
  • Parts for repairs of au mobile phones and their peripheral devices are in stock for 4 years after termination of production (6 years for some models). The parts for repairs are the ones that are required for maintaining the product functions. After the period during which the parts for repairs are in stock, applications for repairs cannot be accepted. Even during this period, some malfunctions may not be able to be repaired due to lack of parts.

    Models for which applications for repairs are or will be terminated (in Japanese only)

  • KDDI shall not bear any responsibility for any change or loss of data (address book, data folders, mail, etc.) that results from malfunction, repair or loss of au mobile phones or from other causes. Back up the data regularly.
