All about IMEI

What is IMEI ?

IMEI is the short term for International Mobile Equipment Identity . It is a unique 15 digit number which is unique for all devices which use cellular devices. This helps us to identify each device differently. We can use this number to block a mobile phone being used by another person if it is lost or stolen . Whenever anyone inserts SIM card ( or turns his cellular device on ) his IMSI number gets registered with his IMEI number.
