Dear I am not an expert about mobiles (a begginer in this field). In my view we need to change IMEI if it is blocked by network. May be others can rectify me if i am wrong about this. OR you may need to give some details about your fault which you are having with your mobile.

Thanks you.. I haven't any fault with my mobile but i need to know why that option impimented in software box.. ( actually what is the reason we need to repair IMEI and why that fault occers )
Coz i need to know more about science.. then we can face faults with our own view.. that's what technician must have..
