This feature ensures the user's SIM card is protected at all times. The moment the SIM is removed from the user's device, this feature will automatically lock the phone and start an alarm, which becomes a deterrent for someone who tries to replace the user’s SIM card. For the authentication of SIM protection, the user needs to set the password and provide an alternate mobile number. The application will also send an SMS to the registered alternate mobile number.

This application also tracks the new SIM and sends the entire information of the inserted new SIM to the user's registered alternate mobile number and email id. The user needs to enable location/GPS tracking to get the current location. It will notify you when the existing SIM is removed and the new SIM is inserted.
