In India, the Samsung Duos series is a popular dual-SIM smartphone choice for many users. These devices allow you to use two SIM cards simultaneously, which is convenient for managing personal and work contacts. However, if you enter the wrong PIN multiple times for slot 1, the SIM card may get locked, and you will need to enter a PUK （Personal Unblocking Key） code to unlock it.
To enter the PUK for slot 1 on a Samsung Duos phone, first, locate the PUK code from your mobile service provider. This code is usually provided in the SIM card packaging or can be obtained by contacting customer support. Then, go to the phone\“s settings, select \“Security\“ or \“SIM card management\“, and choose the option to enter the PUK code for slot 1. Follow the on-screen instructions to input the code and reset your PIN.
This feature is essential for Indian consumers who rely on dual-SIM functionality for better connectivity and cost savings. Always keep your PUK code safe to avoid permanent SIM lock issues. |
