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.
8
Select which phone and computer/Wi-Fi enabled device you will use with the AT&T Home Base:
A cordless phone system with multiple handsets should be used to place phones throughout
your home.
If using an existing phone, unplug it from the wall jack.
For Internet access, you may connect up to 20 devices via Wi-Fi and one via Ethernet
simultaneously.
STEP 1: Set Up Your Device
○
A Install the Back-up Battery and the nano-SIM Card(Optional)
1. Remove the bottom of the device by pushing the entire cover in the direction of the arrow.
2. Install the nano-SIM card (Optional).
9
WARNING!
Your device only supports a nano-SIM card.
To avoid damaging the device, please only use the card that is provided by AT&T and ensure that
the nano-SIM card contacts are facing up when inserting it into the nano-SIM slot.
2. Insert the back-up battery.
3. Replace the cover.
NOTES:
The back-up battery is intended for backup purposes only and may take approximately eighteen (18)
hours to fully charge.
Charge time may be impacted by environmental factors and the back-up battery will stop charging
when the ambient temperature is outside of the temperature range allowed for charging (0°C - 45°F).
○
B Turn on Your Device
1. Plug the power cord into an electrical wall outlet.
2. Connect the other end of the power cord into the Power Input port on the back of your AT&T Home
Base.
3. Slide the ON/OFF button to the ON position and you'll see the power light stays steady green.

○
C Check the Wireless Signal
Wait a few seconds for the signal strength light to turn on, while your device connects to the cellular
network.
Confirm signal strength light is blue for optimal performance. Green indicates a moderate signal and
may be sufficient.
NOTE: If you do not see a blue/green light, you may want to choose another location in your home, such as
near a window or outside wall.
STEP 2: Connect Your Phone
○
AUnplug your Phone from the Wall Jack
The AT&T Home Base is not used with your home phone wall jack.
NOTE: If you have a cordless phone, keep it plugged into a power outlet.
