Dual sim card adapter for mobile device

An apparatus for a dual Subscriber Identity Module (SIM) card adapter comprising:

• a connector operational to be entered into a SIM card slot for a mobile device,
• said connector comprising an input and an output,
• wherein the connector input is coupled to the mobile device, and comprises a first plurality of connection pins,
• the connector output comprises a second plurality of connection pins, and
• wherein respective ones of said plurality of connection pins of said connector input are communicatively coupled to a corresponding connection pin of said plurality of connection pins of said connector output;
• a switch comprising an input and at least two outputs,
• the switch input comprising a plurality of connection pins,
• each of the at least two switch outputs comprising a plurality of connection pins, and
• said switch operational to couple the switch input to a selected switch output,
• wherein respective ones of said plurality of connection pins of said switch input are coupled to a corresponding connection pin of said plurality of connection pins of said selected switch output;
• at least two integrated SIM card holders,
• each of the at least two integrated SIM card holders comprising a plurality of connection pins;
• and
• wherein
• said switch input is coupled to said connector output, such that respective ones of said plurality of connection pins of said switch input are coupled to a corresponding connection pin of said plurality of connection pins of said connector output,
• each of said at least two switch outputs is coupled to a corresponding integrated SIM card holder, each connection pin of said plurality of connection pins of said switch output being coupled to a corresponding connection pin of said plurality of connection pins of said integrated SIM card holder,
• to form a signal communication path starting at the connector input and ending at a selected one of the at least two integrated SIM card holders that is coupled to the selected switch output, so that signals can travel bidirectionally between the selected one of the at least two integrated SIM card holder and the mobile device.
