This product is an adapter that connects a mobile phone (smartphone) to a landline phone, allowing you to make and receive calls using the mobile network with the landline handset. It's convenient for those who find smartphones difficult to operate or who want to use a landline phone in facilities or offices. I used it to communicate with my grandmother who lived in a facility. She could talk to family members using the landline handset, which was a great help. Now that it has served its purpose, I'm offering it to someone who needs it. ── ■ How it Works ・Connect your smartphone to the main unit via Bluetooth ・Connect your landline phone to the main unit → You can make and receive calls using your smartphone number on the landline phone ■ Compatible Mobile Phones ・iPhone / Android ・Bluetooth-enabled feature phones ・Compatible with docomo / au / SoftBank / Y!mobile / MVNO ※ Not compatible with Rakuten Mobile "Saikyo Plan" and "Rakuten UN-LIMIT (dedicated app calls)" (regular voice calls are not guaranteed) ■ Compatible Landline Phones ・Home phones ・Black dial phones ・Business phones (analog) ・CTI devices ※ FAX/Modems not supported (voice calls only) ── ■ Main Uses ・Smartphone call support for the elderly ・Personal phone in nursing homes ・Sharing mobile network with business phones ・Converting a home phone to a landline ■ Features ・Caller ID support ・High sound quality (echo cancellation / noise reduction) ・Lightweight / energy-saving / compact ・Voice recognition support ── 【Condition & Accessories】 ・Purchased September 2025 / Used for about 2 months ・Operation confirmed / Initialized ・Main unit / AC adapter / Instruction manual ※ Landline phone not included ※ There is a toy poodle at home (no contact during storage) 【Shipping】 Takkyubin Compact or Takkyubin (bubble wrap packaging) This is a convenient device that allows you to use your smartphone network with a familiar landline phone.
