No Cell Phones Sign - Clear Visual Policy Indicator for Public Spaces #3334677 (License: Personal Use)

The image features a classic prohibition symbol-a red circle with a diagonal slash-overlaying a black silhouette of an older-style mobile phone with a physical keypad and antenna. Below the icon, the words “NO CELL PHONES” are displayed in bold, uppercase, sans-serif font for maximum legibility. The high-contrast design ensures visibility from a distance and across diverse lighting conditions.

Commonly used in environments requiring silence or undivided attention-such as libraries, exam halls, religious venues, medical facilities, courtrooms, and performance theaters-to communicate device restrictions visually and unambiguously.
