Your Google Fiber Phone service at home requires an internet connection and power supply. Certain conditions, such as a power outage, will interrupt your Google Fiber Phone service, including 911, unless you have battery backup or an Uninterruptible Power Supply (UPS). If your home already uses a permanently installed generator to deliver backup power during an outage, you probably don't need a battery backup or a UPS.
Although you can make and receive calls (with the exception of 911 emergency service) on your mobile phone using Google Voice, we recommend battery backup to ensure 911 service on your home phone.
Battery backup options
We offer an optional battery backup unit you can purchase when you sign up for Google Fiber service (or when you add Google Fiber Phone to your existing service). Our battery backup delivers up to 24 hours of backup power and maintains 911 service on your home phone. If you choose this option, our installation specialist will deliver and set up the unit during your appointment.
Check your network connections
Your Google Fiber Phone Box is connected to the internet through your router and Fiber Jack. If you have power, but your Google Fiber Phone home service is unavailable, your router or Fiber Jack may be the cause of the interruption.
