The International Mobile Equipment Identity or IMEI is a number unique to every GSM and UMTS mobile phone.

The IMEI number is used by the GSM network to identify valid devices and therefore can be used to stop a stolen phone from accessing the network. For example, if a mobile phone is stolen, the owner can call his or her network provider and instruct them to "ban" the phone using its IMEI number. This renders the phone useless, regardless of whether the phone's SIM is changed.

IMSI An International Mobile Subscriber Identity, or IMSI is a unique number associated with all GSM and Universal Mobile Telecommunications System (UMTS) network mobile phone users.
It is stored in the Subscriber Identity Module (SIM) inside the phone and is sent by the phone to the network.
