title: Is it possible to unlock the sim and let the software put in the pincode
body: <p>I´m going to give away phones (Android) to clients (mostly kids) and want to create a ´lock´-app.
  I don´t want the clients to bother with the pincode for the phone, but when you turn on the device, the ´lock´-app should just start. I then overwrite the buttons and they shouldn´t be able to make phonecalls.</p>
  
  <p>Only thing is, in case of removal of the sim, or in case of theft, I want a pincode on the simcard. So is it possible that my ´lock´-app unlocks the sim by putting in the pin by code?</p>
  
  <p>How can I do that?</p>
