1. A mobile device, comprising: an interface to establish an electrical contact with a universal integrated circuit card; a memory to store: proprietary feature services and proprietary applications associated with two or more cellular carriers; a processor, coupled to the memory, to: determine that a first universal integrated circuit card inserted into the interface is associated with one of the two or more cellular carriers; enable, based on the first universal integrated circuit card being associated with the one of the two or more cellular carriers, one or more proprietary feature services, of the proprietary feature services, that are associated with the one of the two or more cellular carriers, and one or more proprietary applications, of the proprietary applications, that are associated with the one of the two or more cellular carriers; detect removal of the first universal integrated circuit card from the interface; determine that a second universal integrated circuit card, inserted into the interface subsequent to the removal of the first universal integrated circuit card from the interface, is not associated with the two or more cellular carriers; disable, based on determining that the second universal integrated circuit card is not associated with the two or more cellular carriers, the one or more proprietary feature services and the one or more proprietary applications; convert, based on determining that the second universal integrated circuit card is not associated with the two or more cellular carriers, data generated by the one or more proprietary feature services or the one or more proprietary applications into a non-proprietary format; and enable, based on the second universal integrated circuit card not being associated with the two or more cellular carriers, one or more base feature services, and one or more non-proprietary applications, the one or more base feature services and the one or more non-proprietary applications being capable of utilizing the data in the non-proprietary format.
