1. A method, carried out by a private mobile wireless terminal comprising a subscriber identification module applet, for persisting a connectivity preference for a home mobile wireless network that is a private mobile wireless network, wherein the private mobile wireless terminal operates in a mobile wireless environment comprising a primarily mobile network provider including a sponsored roaming application server (SRAS), and wherein the method comprises:
performing a network scan to identify candidate mobile wireless networks within operating range of the private mobile network device and then connecting to the private mobile wireless network that is indicated as the recent/preferred mobile network for mobile wireless connections;
reporting the established connection, to the private mobile wireless network, to the SRAS;
losing the established connection as a result of the private mobile wireless network being in an out of service state;
performing a supplemental wireless network scan to identify candidate mobile wireless networks within operating range of the private mobile network device and then establishing a new connection to an alternative secondary mobile wireless network that is indicated as an acceptable replacement for the private mobile wireless network;
receiving a trigger message issued by the SRAS that invokes the SIM applet to perform a series of operations to restore a persisted connectivity preference for connecting to the private mobile wireless network after service is restored following a service outage of the private mobile wireless network.
