Abstract: In aspects of device resource savings during cellular out-of-service condition, a device includes a cellular radio for cellular network communication via a cellular network. The device implements a communication manager that detects an out-of-service condition for lack of a cellular network connection with the device. The communication manager can communicate a notification to collaborative devices that the device is a master device implemented to scan for the cellular network during the out-of-service condition, and the notification serves to initiate the collaborative devices saving resources by switching-off respective cellular radios. The communication manager can initiate scans to detect the cellular network and establish the cellular network connection with the cellular network, and then communicate scan data associated with detection of the cellular network to the collaborative devices that use the scan data to establish respective cellular network connections with the cellular network.
