No Mobile Phones Allowed Sign | Prohibition Symbol for Phones #3756874 (License: Personal Use)

The image displays a standard prohibition sign: a bold red circle with a diagonal red slash overlaying two stylized smartphones-one black, one gray-positioned side by side. The phones feature simplified keypads and screens, emphasizing their identity as communication devices. The high-contrast design ensures immediate recognition and compliance in public or restricted environments.

Used on signage in libraries, classrooms, exam halls, courtrooms, hospitals, and secure facilities to enforce silence or prevent recording/data leakage. Matches user intent seeking visual cues for phone restrictions or designing policy-compliant signage.
