One Bluetooth link. Every phone in your house.

Cell2Jack pairs to your cell phone the same way your car does: Bluetooth, paired once. Then it feeds your cell service into your home phones. They ring, dial, and answer with your cell number. The landline company is no longer involved.

  1. Connect a home phone to Cell2Jack's Phone port. Or connect Cell2Jack to a wall jack and reach every phone in the house.
  2. Pair your cell phone once, over Bluetooth. Up to 2 cell phones can pair.
  3. Set your cell phone down when you get home. Every connected phone works.

What happens on a call

When someone calls your cell number, your cell phone answers over the cell network as usual. Cell2Jack hears the call over Bluetooth and puts it on the phone line it feeds, so your home phones ring. Pick up any of them. Dialing out works the same way in reverse: the home phone's keypad drives your cell phone.

Your old landline number can come along. Port it to your cell plan and it keeps working on every phone in the house.

What's inside

One board.

The entire device is a single circuit board in a white housing.

Three ports.

Phone, 5V in, 5V out. Nothing to configure. The 5V out port charges your cell phone while it sits nearby.

No moving parts.

Nothing to wear out.

About cell phone radiation

A home phone puts distance between the cell phone and your head. In 2011, the World Health Organization's cancer research agency classified the radio signal from cell phones as Group 2B, meaning possibly carcinogenic to humans [1]. With Cell2Jack, calls come through your home phones, so your cell phone can sit across the room.
