What is will a phone ring if it is dead?

No, a phone will not ring if it is dead. When a phone's battery is completely drained, it cannot power up the necessary components to receive or send signals to the wireless network. Therefore, any incoming calls or messages will not be able to reach the device, and the phone will not ring or vibrate. Additionally, if the phone is turned off, it also cannot receive calls or messages until it is powered back on.
