title: SIM Applet development
body: <p>I need to develop a SIM applet that would enable the SIM card holding multiple SIM's(Super SIM) to automatically switch between its numbers based on network strength.Is it even possible??</p>
  
  <p>Secondly, for this i believe i need to access the directory files in the SIM. Does anyone have an idea how that is possible?? I have figured that i need to develop the applet code on the java development kit. But how do i access the files from my code?</p>
  
  <p>Thirdly, all the information is sent to the SIM via the modem in the handset which is controlled by the controller inside the handset. Do i need to program that too apart from the applet?</p>
  
  <p>Kindly help me with any kind of information you may have. Any set of instructions regarding the steps to be followed will be a big help.</p>
