If you have forgotten the security code for your Nokia 100, there are a few options that you can try to regain access to your phone.
Try default codes: Some Nokia phones have default security codes that can be used to unlock the phone if the original code is forgotten. Some common default codes for Nokia phones include 12345, 00000, and 123456789. You can try these codes to see if one of them works for your phone.
Use a code generator: There are a number of online code generators that claim to be able to generate a code to unlock your Nokia 100 based on your phone's IMEI number. These generators typically require you to enter your IMEI number and select your phone model, and then they will provide you with a code to enter. Keep in mind that the effectiveness of these generators can vary, and some may not work for your phone.
Contact Nokia customer support: If none of the above options work, you can try contacting Nokia customer support for assistance. They may be able to provide you with a code to unlock your phone or guide you through the process of resetting it.
