Cell2Jack can work with Google Voice to make free local and long distance calls on your old home phone. It takes a helper app and some setup.

  1. Install Google Voice on an Android phone running Android 7.0 or newer. No SIM card is required.
  2. Set up Google Voice and confirm you can make and answer calls with it, on its own, before you connect it to Cell2Jack.
  3. Install the Cell2Jack helper app for your hardware version and follow the setup video.

The helper app is not available for download on this site yet.

Google keeps changing Google Voice, so ringing and dialing may stop working. When that happens, you may need to answer and dial on the cell phone, then pick up the home phone to talk.
