Tools and techniques for providing seamless enterprise and consumer mobility are described. More particularly, the tools manage network connections between a communications device and two or more networks. A first network has a first type, and a second network has a second type different type than the first network. When the communications device is proximate the first network, a first device detection signal is generated. Also, a first presence signal is associated with the first network, and varies in response to a condition of a connection between the communications device and the first network. The first presence signal indicates whether the condition of the connection permits an ongoing communication to use the first network. When the condition of the connection does not permit the ongoing communication to continue using the first network, the communication is handed over to the second network.
