Abstract: Systems, products, and methods are disclosed for performing a method of protecting system-provider information stored within a mobile communications device that has one or more communications ports and one or more radios. Illustratively, the method includes receiving a request to access the system-provider information, determining that the request was communicated over the air by way of a wireless telecommunications network that the mobile communications device is authorized to access, which network is accessible by way of the one or more radios; and permitting access to the system-provider information after determining that the request was communicated over the air, such that any request to modify the system-provider information by any of the one or more communications ports is denied, and only the request communicated over the air is allowed to be used to modify the system-provider information.

Abstract: Systems, products, and methods are disclosed for performing a method of selectively controlling communications through a communications port of a mobile communications device. The system-provider information is useable by the mobile communications device to communicate with a wireless telecommunications network that is designated in the system-provider information. Illustratively, the method includes presenting a user interface on the mobile communications device. The UI exposes an option to enable the communications port to be useable to modify the system-provider information. The mobile communications device can be in a first state that currently prohibits data from being passed through the communications port to the system-provider information. Input is received that is to be used to enable data to be passed through the communications port to the system-provider information.
