codes & passwords
Your phone’s 4-digit unlock code is originally set to 1234.
The 6-digit security code is originally set to 000000. If your
service provider didn’t change these codes, you should
change them:
Find it: Press - > Settings > Security > New 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 - and enter your 6-digit
security code instead.
If you forget other codes: If you forget your security code,
SIM PIN code, PIN2 code, or call barring password, contact
your service provider.
lock & unlock phone
You can lock your phone to keep others from using it. To lock
or unlock your phone, you need the 4-digit unlock code.
To manually lock your phone: Press - > Settings > Security
> Phone Lock > Lock Now.
To automatically lock your phone whenever you turn it off:
Press - > Settings > Security > Phone Lock > Automatic Lock > On.
Note: You can make emergency calls on a locked phone (see
page 48). A locked phone still rings or vibrates for incoming
calls or messages, but you need to unlock it to answer.
