The right battery backup for you depends on the type of phone service you have. Review the options to identify your service and equipment type. Not sure what you have? Call us at 800.650.0954 for more help.
Good to know: Before you install a battery backup, make sure you unplug your Wi-Fi gateway. Keep it unplugged while you connect your backup power supply. During this time, your AT&T Internet, Phone, and U-verse TV service will be interrupted. (This includes any scheduled recordings.)
