No Cell Phone Sign - Prohibition Symbol for Mobile Device Restrictions #2217511 (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 environments where electronic devices must be silenced or disabled.

Commonly used in hospitals, theaters, classrooms, airplanes, secure facilities, and exam rooms to indicate areas where mobile phone use is prohibited for safety, privacy, or courtesy reasons. Matches user intent for finding signage assets or understanding regulatory symbols.
