Method of coupling wireless portable communications device to electronic mail server by public wireless communications network when out of communication with private wireless communications network

摘要

A method of coupling a wireless portable communications device (PCD) to an electronic mail server network by way of a public wireless communications network is disclosed. The PCD is normally in communication with the electronic mail server network by way of a private wireless communications network, and is coupled to the electronic mail server network by way of the public wireless communications network when the PCD is out of communication with the electronic mail server network by way of the private wireless communications network. In particular, the PCD is coupled to the public wireless communications network, and is caused to leave an electronic mail server network mode and enter a public wireless communications network mode. A network connection is established with the electronic mail server network by way of the public wireless communications network, and communication with the electronic mail server network is entered into by way of the public wireless communications network.
