1)IF U HAVE THE EMI NUMBER I THINK NOKIA CAN MAKE THE PHONE UNUSABLE. YOU MUST PROVIDE BILL.

2)IF UR SIM IS IN THE CELL THE POLICE CAN TRACE THE LOCATION.

3) IF U KNOW THE KARWA TAXI NUMBER, YOU CAN FIND YOUR CELL BACK, IF YOU WERE SITTING IN THE FRONT SEAT. IF YOU WERE SITTING AT THE BACK, EVEN IF THE DRIVER HAS TAKEN IT HE CAN CLAIM OTHER PASSENGER MUST HAVE TAKEN IT.

TRY ANY OF THESE :)
