xx4all said:sim no is used to track the call records. imei is used to track down the changes of sim. current system in sl cant track real time location. only thing they cn provide is tower location.
yeah.. only the tower... cuz every time when the phn is switched on it will update the sim location(current signelling tower location) to VLR ryt? so ure telling it will also record the imei number of the phn also? ahaa.. thanks for the info..
