Erasing a SIM card involves resetting it to its factory settings, which can be necessary for various reasons such as selling the card, switching to a new carrier, or troubleshooting issues. When a SIM card is erased, all the data stored on it, including contacts, messages, and call logs, is permanently deleted.
Erasing a SIM card is a relatively simple process that can be done in a few steps. First, power off the device that the SIM card is inserted into. Then, remove the SIM card from the device. Once the SIM card is removed, locate the small hole on the side of the card. Using a SIM ejector tool or a straightened paperclip, gently insert the tool into the hole and press down until the SIM card tray ejects. Finally, remove the SIM card from the tray and erase it using a computer or a dedicated SIM card eraser.
