This image features a single no mobile phone prohibition icon presented in a clear and minimal layout. The symbol shows a mobile phone crossed by a bold red diagonal line within a circular border, set against a bright yellow background for high visibility and instant recognition.

The flat PNG design follows a minimalist style with consistent shapes and strong contrast. It is suitable for examination halls, workplaces, restricted zones, meetings, public facilities, websites, mobile applications, and user interface elements where mobile phone usage is not permitted.
