No Cell Phone Sign -禁止手机使用标识图标 #2217150 (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, making it suitable for public signage where silent or device-free zones are enforced. It conveys a strict restriction on phone usage without relying on text, supporting multilingual environments.

Used in libraries, classrooms, theaters, hospitals, exam halls, and secure facilities to indicate areas where mobile phone use is prohibited. Matches user intent for finding visual signage templates, safety compliance graphics, or accessibility resources.
