KDDI terminated its service to update ACR data integrated into phone devices with an ACR function (e.g. α series) and an external adapter (α mini and α mini II) on December 31, 2007. As the focus of telephone services offered to our customers shifted to MYLINE and au HIKARI Phone service, we have decided to terminate the service due to a decrease in opportunities to use the ACR function for selecting telecommunications carriers. We would like to express our sincere gratitude for your past patronage.
- The ACR function currently configured on the ACR-supporting phones and external adapters is still available. However, please cancel the ACR function upon continuing the use of your ACR-supporting phone or adapter when your area code has changed for any reason including moving after December 31, 2007 (If your MYLINE registration is not with KDDI, you will not be using KDDI).
- The lease agreements for external adapters will be terminated with the discontinuation of the provision of the ACR data update service.
- KDDI recommends the use of 0077 calls through the au HIKARI Phone service and MYLINE registration for a convenient and less expensive use of KDDI phone services.
- ACR function is a telephone function that automatically places identification codes to compare calling rates of carriers so that the least expensive carrier is chosen.
