Motorola W377 is a clamshell cell phone with numerous features. The phone has a factory default unlock code as well as a security code. If the phone asks for this code, you can simply enter it to unlock the hand-held device. However, if your cell phone service provider has changed these codes, you will need to contact them to retrieve the new code.
Enter "1234" when the phone's screen reads "Enter Unlock Code."
Enter the last four digits of your phone number if "1234" doesn't work.
Press the "Menu" button and enter the security code if neither of the above-mentioned methods work. The default security code for Motorola W370 is "000000."
Contact your service provider if you're unable to unlock using any other method.
