hey, plz mail me if any of u have a pcb design for the sim reader by dejan. i have the schematics. i tried to make it, but not working, i dont know what is the problem,,,,, may be my un managed design is creating a problem.

tell me if u guys have faced same problem after making sim reader as per schematics by dejan..

"Fatal Error: Card dont send answer to reset."

when the s/w asks for an enter, the led glows up but it ends up with an error and when i close the error window led lights off

it should not be any problem if you are using the 74Hc04 chip.you can't use the 74LS04,it will not work.unless you have wrong connection.

are you using the 74LS04 chip.
you can use the 4069 chip too.
