Hi, my phone was stolen ! 
I want to know can that thief change the serial number ???!!
which serial number.......if you activated any antivirus according threw it ...then it will mail you when they changed the simcard....
track you mobile threw the sim!!
No the SI number is unic.
Serial Number as in IMEI cannot be changed .
SI number is simply Sales Identifier ( Firmware Customization according to market ) has no effect.
If you had any security software then you have a good chance of locating the device else no chance
