ABSTRACT:
A portable communications device (PCD) is coupled to a first network by way of a second network. The PCD is normally in radio communication with the first network, and is coupled to the first network by way of the second network when the PCD is out of radio communication with the first network. In particular, the PCD is coupled to the second network, and is caused to leave a first network mode and enter a second network mode. A network connection is established with the first network by way of the second network, and communication with the first network is entered into by way of the second network.
