Abstract
Methods and systems are provided for alerting a calling or message sending party as to whether a desired receiving wireless electronic communication device is off or out of range for sending and receiving transmissions. When a call is placed to a wireless telephone or when a message or page is placed to a wireless communication device such as a pager, text messaging device, or personal digital assistant, the operational status of the receiving wireless telephone or other wireless communication device is checked by the wireless network in which the wireless device operates. A message or call is returned to the calling party or sender to alert the calling party or sender if the desired receiving device is off or out of range so that the calling party or message sending party may choose an alternate means of communicating with the desired receiving party.
