Learning to Use Your Phone - 39
Changing a Code or Password
Your 4-digit unlock code is originally set to 1234, and the 6-digit 
security code is originally set to 000000. Your service provider may 
reset these numbers before you receive your phone.
If your service provider has not reset these numbers, we 
recommend that you change them to prevent others from 
accessing your personal information or modifying your phone 
settings. The unlock code must contain 4 digits, and the security 
code must contain 6 digits. 
You can reset your 
Unlock Code, Security Code, SIM PIN2, or Bar Password 
for call barring. 
If You Forget a Code or Password
If you forget your security code (originally set to 000000), SIM PIN, 
SIM PIN2, or call barring password, contact your service provider.
If you forget your unlock code, try entering 1234 or the last 4 digits 
of your phone number. If that does not work, do the following when 
you see the
