All About IMEI
Blacklist of stolen devices
When mobile equipment is stolen or lost, the owner can typically contact their local operator with a request that it should be blocked. If the local operator possesses an Equipment Identity Register (EIR), it then will put the device IMEI into it, and can optionally communicate this to the Central Equipment Identity Register (CEIR) which blacklists the device in all other operator switches that use the CEIR.
Phone is Lost > Contact local Operator > Local Operator communicates to CEIR > device is blocked on all Operators Vodafone, Idea, Tata and so on.
