No Cell Phones Sign - Prohibition Symbol for Mobile Device Restrictions #98274 (License: Personal Use)

The image displays a standard prohibition symbol: a bold red circle with a diagonal slash overlaid on a black silhouette of an older-style mobile phone with a physical keypad and antenna. The high-contrast design ensures immediate recognition and compliance in public or sensitive environments. It communicates a strict ban on mobile phone use, often enforced in places requiring silence or security.

Used on signage in libraries, hospitals, exam halls, courtrooms, theaters, and secure facilities to indicate that mobile phone usage is prohibited. Matches user intent for finding visual symbols for policy enforcement or wayfinding design.
