How It Works
The Wireless Home Phone device uses the AT&T cellular network
to provide phone service to your cordless or corded home
phone(s). Place it anywhere in your house where you have a
wireless signal. It does not require the use of a home phone wall
jack like traditional home phone service.
The Wireless Home Phone device provides many calling services,
such as voicemail, Caller Number ID, Call Waiting, Call Forwarding,
and 3-way Calling for your home phone(s). It also includes a back-
up battery in case of a power outage.
