Access codes overview
Access codes consist of the lock code and security code. When
you get your phone, you should change these codes from their
defaults, write down the new codes, and keep them in a safe
place away from the phone. Avoid using access codes that
are similar to emergency numbers, such as 911, to prevent
accidental dialing of the emergency number.

Depending on your service provider, the default lock code is
either 1234 or the last four digits of your phone number.
