codes & passwords
Your phone's unlock code is originally set to 1234. The security code is originally set to 000000. If your service provider didn't change these codes, you should change them:
Find it: M> Settings > Security > New Passwords
You can also change your SIM PIN or call barring passwords.
If you forget your unlock code: At the Enter Unlock Code prompt, try entering 1234 or the last four digits of your phone number. If that doesn't work, press Mand enter your security code instead.
If you forget your other codes: If you forget your security code, SIM PIN code, PIN2 code, or call barring password, contact your service provider.
