Abstract
A method includes: a wireless communication device (WCD) receiving information indicating that a second user device that is close-by is actively running a messaging application, which establishes an active communication channel with a communication service that is responsible for routing incoming voice and data communication to the WCD. The method also includes: establishing a short range communication between the communication device and the second user device; in response to receiving the information and establishing the short range communication, placing at least a first modem of the WCD in a sleep state; and in response to at least one subsequent trigger event, awakening the first modem to an active state to enable use of the first modem to complete communication. The messaging service is configured to redirect incoming calls to the second user device while the messaging service is active and the devices are within short-range communication of each other.
