Disclosed are methods, apparatus and computer program products that provide an enhanced multi-SIM wireless communication device. For example, a method includes providing in a wireless communication device a protocol stack software component composed of a first native protocol stack software and a second native protocol stack software each comprising layer 1, layer 2 and layer 3 protocol stack functionality. The first native protocol stack software and the second native protocol stack software are each associated with a respective subscriber identity module and are independent of one another. The method further includes providing in the wireless communication device a common software component that includes protocol stack framework software elements, a hardware arbitration layer and a hardware adaptation layer. The method further includes linking the protocol stack software component and the common software component into a modem software executable capable of operation with hardware of the wireless communication device.
