In today’s digital age, mobile phones have become an essential part of our daily lives. They allow us to stay connected with our loved ones, access important information, and stay entertained. However, when we encounter problems with our mobile devices, it can be frustrating and cause inconvenience. One of the most common issues that users face is the “SIM card not detected” problem.

When a mobile phone displays the message “SIM card not detected”, it means that the device is unable to recognize the SIM card inserted in it.
