VIRTULISATION ON MOBILE PHONES

IS THERE A MOBILE PHONE AROUND THAT CAN VIRTUALIZE ITS SIM CARD? WHAT I MEAN IS THAT INSTEAD OF USING LETS SAY A DUAL SIM PHONE, THE SIM COULD BE SOFTWARE BASED,THAT WAY IT USE MORE THAN A SIM CARD WITHOUT HAVING TO INCREASE THE NUMBER OF SIM SLOTS. I AM PUTTING THIS FORWARD BECAUSE IN MYCOUNTRY,THE AVERAGE PHONE USER MAKES USE OF MORE THAN ONE TELCO THIS MAKES PEOPLE CARRY SEVERAL MOBILES AT ONCE,WHICH TO ME IS UNNECESSARY.
