How It Works
The AT&T Home Base uses the AT&T cellular network to provide phone service to your cordless or
corded home phone(s) and Internet access to your computer and Wi-Fi enabled devices. Place it
anywhere in your home where you have a strong wireless signal. It does not require the use of a home
phone wall jack like traditional home phone service.
The AT&T Home Base provides many calling services, such as voicemail, Caller Number ID, Call
Waiting, Call Forwarding, and Three-way Calling for your home phone(s). It also includes a back-up
battery in case of a power outage.
Device Installation
Before You Begin
The AT&T Home Base works exclusively with the AT&T cellular network and DOES NOT use your
home phone wall jacks.
Your device should be located:
Where you have a strong signal from a cell tower, typically near a window or outside wall.
Signal strength may vary in different parts of your home.
Near an electrical wall outlet.
In the general area where you’ll be using your home phone, computer, or Wi-Fi enabled
devices.
