Abstract
A mobile communication device. The device comprises a first wireless communication identity stored in a first partition of the memory, wherein a wireless communication identity comprises a network access identity, a list of wireless communication systems to which the device is authorized to attach, a rule set for prioritizing among the wireless communication systems identified in the list, and a table of device rules. The device further comprises an application stored in the memory that, when executed by the processor, detects a triggering event and in response to the triggering event changes the active wireless communication identity of the mobile communication device to one of the wireless communication identities stored in the partitions of the memory and applies device rules associated with the wireless communication identity, where the mobile communication device conducts wireless communication via the radio transceiver based on the active communication identity and the associated device rules.
