This emoji shows a mobile phone inside a red prohibited sign, thus indicating that mobile phones should not be brought or used in an area. Most platforms display the phone as having a black background, with some showing it in front of a white backdrop.

This sign is typically found in areas where the use of cell phones is not allowed, such as in a classroom, hospital, or other designated quiet areas, during an exam, or in certain designated public areas where it may be dangerous to use a cell phone. The sign is usually with a white background and black lettering.
