Your Home Phone Unlimited service uses electrical power to function. If you lose power, you will require a Battery Backup Unit (BBU) to power your phone and keep it connected to make phone calls, including emergency 911 calls.
To be sure you are protected with this function, find your service below to order a Battery Backup Unit. Installing any Battery Backup Unit is optional for all Home Phone Unlimited customers. Please note: Battery backup only provides access to your Digital Voice service during a power outage. It will not work for your Ziply Fiber Internet and/or Video Service.
See below for your service. If you're not sure which voice service you have, click to chat with a representative.
