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.
