How it works
The Wireless Home Phone device uses the AT&T cellular
network to provide phone service to
y
our cordless or corded
home phone(s). Place it anywhere in your house where you have
a wireless si
g
nal. It does not require the use of a home phone
wall jack like traditional home
p
hone service.
The Wireless Home Phone device provides many calling
services, such as voicemail, Caller Number ID, Call Waitin
g
, Call
Forwarding, and Three-way Calling for your home phone(s).
