Assuming the handset is 'unlocked' - the thief can simply change the SIM card for another one - and use it as if it was their own.

EVERY mobile device - whether that's a simple pager, cheap mobile phone or computer 'dongle' - has an IMEI number assigned to it. The IMEI number is unique to the device - NO two devices have the same number.. Mobile phone companies have the ability to BLOCK the IMEI number - which renders the device unusable.
