摘要: Methods and apparatus for controlling power to electrical circuitry of a wireless communication device having Subscriber Identity Module (SIM) interface are described. In one illustrative embodiment, method includes the acts receiving down signal from user device; powering radio frequency (RF) transceiver in response signal; maintaining SIM while RF is powered signal. A visual display capable displaying information (e.g. address book information) card
