A mobile information device (MID) incorporates a handset having a primary applications processor, a primary display, a primary input keyboard, a second input keypad, a second display having reduced functionality from the primary display and a card interface. A miniaturized form factor card is received in the card interface which includes a second processor and wireless communications components. The interface provides operable connection from the second processor to the second input keypad and second display. During operations of simple voice call or comparable functions, the primary applications processor, primary display and primary keyboard remain in sleep mode to reduce power consumption for the MID with the call functionality provided by the second processor, second keyboard and second display. During operations requiring higher level functionality, the primary applications processor, primary display and primary keyboard are awakened to provide the necessary capability.
