au Home Plus Denwa
ホームプラス電話 hōmu purasu denwa
KDDI's construction-free fixed telephone product that uses a dedicated adapter and the mobile network at the registered location.
It is different from an analogue line and from fibre telephone even if a local-looking telephone number is used. Availability, number portability, emergency calls, fax or connected-device compatibility and set discounts must be checked for the current product conditions.
Because it uses mobile radio and powered equipment, indoor signal and a power outage can affect service. Confirm the exact adapter placement and keep another emergency communication method.
