Guys before you spend money for a new version of cadi, ask if it will work on a controller without a Sim Card. Schindler changed the controller software so even their cadi does not work without Sim. One of the majors has developed a Sim Card Simulator where you plug their tool in, run a specific program and the controller thinks it has a Sim Card until power is cycled. This will allow you to use UIT or Cadi without a Sim Card until power is cycled. Then you run the Sim Card program again and you can use tools again until power cycled.
