PLEASE help|||That code should have been included with the phone, in the packaging. Look through all the papers and booklets that came with your phone. There must be a paper with this code on it. Usually it's with the sim-card and the PUKcode.|||the code should be 00000000|||its the last 4 digits of ur number
