Wireless communication devices can be designated for group communication. A communication device, which may be part of the designated communication group, originates an emergency message to the communication group. Upon receipt of the emergency message, each wireless communication device that receives the message generates an alarm to alert the user to the arrival of an emergency message. Upon receipt of the emergency message, the user of each of the communication devices activates a response device to indicate that the emergency message has been received. The message originator receives the confirmation messages to determine that each of the members of the communication group have received the emergency message. If a device has not received the emergency message, transmission may be repeated or messages sent to the other group members to notify them of the failure of the device to respond to the emergency message.
