as we know their are 6 pins of sim connector out of which 5 pins r used now the pin which is opposite to ground pin provide voltage to sim to work ....
now power on ur phone then immediately remove battery and check is supply pin get short with ground ....
if it get shorted then only solution is cut supply track coming from sim connector ....
the supply voltage is 1.8 to3v now u can give supply to sim from some other component...
for voltages supply u can refer to circuit ...

i have tried this method in many other phones it really work plz post result...........
