        The process of PIN unlocking the modem is now performed with the
        
          SendPin()
        
        method in the
        
          org.freedesktop.ModemManager1.Sim
        
        interface.
      
        The path of the SIM object is specified in the
        
          Sim
        
        property of the
        
          org.freedesktop.ModemManager1.Modem
        
        interface. If the modem doesn't have a SIM, no object path will be given.
