A contactability of a user can be maintained by identifying a secondary device and causing a contact device to establish a communication session with the secondary device when a primary device becomes unavailable. In some embodiments, when a power level of a primary device falls below a threshold, the primary device can identify a secondary device previously associated with the primary device. The secondary device can receive a signal periodically from the primary device. In response to ceasing to receive the signal that is being sent periodically from the primary device, the secondary device in some embodiments can send a notification to a contact device to inform the contact device to send a communication request to the secondary device. The secondary device can receive the communication request from the contact device and establish a communication session with the contact device.
