I forget my security code my mobile is nokia 3120 classic

SOURCE: i forget my nokia 3120 classic mobile security code so how can i

IMEI(International Mobile Equipment Identity) needed to get you the master code.The imei number is a 15 digit number and with that I can provide you the master code which acts as security/master code.
THE MASTER CODE HAS TO BE TYPED 3 TIMES ONLY , SO BE AWARE.
The master code can be typed as security code,when the phone asks for code.
The pin number is different from this master code,since it is attached SIM(subscriber identity module) card
"OR"
"Give it to the Nokia care centre,they will clear it in 5 minutes(without asking any questions to you)"
