The IMEI is the unique identifier for the phone physically
(International Mobile Equipment Identity) -
http://en.wikipedia.org/wiki/IMEI.  The SIM card has a unique serial
number as well - http://en.wikipedia.org/wiki/SIM_Serial_Number.  

This is why I was trying to find out what the carriers tied the data
plan to.  They try to track the IMEI - or AT&T makes the appearance they
do.  I found this out when we swapped in unlocked GSM phones and it
caused them confusion (which made me happy!).
