Getting Started

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 Three-way Calling for your home

phone(s).

Device Installation

Before You Begin

Your device 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 cellular signal, typically near a

window or outside wall. Signal strength may vary in different

parts of your home.

• Near an electrical wall outlet.
Select which phone(s) you will use with the Wireless Home

Phone device:
• 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.

Install the Battery

Insert the battery.

Note: Battery must be installed at all times for your

Wireless Home Phone device to operate.

Install the battery cover.

NOTES:
•

The battery must be installed at all times for your

Wireless Home Phone device to operate properly, even

when plugged into a power source. It may take five (5) hours

to fully charge (battery will charge inside the device while

connected to a power supply).

• Charge time may be impacted by environmental factors,

and the battery will stop charging when the ambient

temperature is outside of the temperature range allowed

for charging (32 °F – 131 °F).
