# If I Lose Power or My Internet Connection, Will I Lose Phone Service?

## Physical desk phones and My.Phone.com require internet access and power to function.

If you have installed our mobile app for iOS or Android, you will be able to make and receive calls on your device using your cellular network if Wi-Fi isn't available.

For hardware, battery backup systems can help, but remember to put all of your network and phone hardware on battery power.
