Ringing cell phone in the public place

In an information-based society, the cell phone is one of the important items to get information and maintain communication. As the number of cell phones increased, it makes more problems like making a place noisy and causing ill manners, especially in public places such as in the classroom, subway and library. It has become a problem that some people who use cell phones make others feel uncomfortable. Sometimes unique ring tones such as some song or sound make people feel unique because it shows other people as different than other people. However, ringing in the classroom and library can cause a different reaction from other people. Furthermore, it is not a matter that is supposed to be allowed in that kind of place. Some countries tried to make a system that makes it so people cannot use cell phones in public place, where it is not supposed to be used. In that kind of place, cell phones do not work, so a ringing cell phone cannot bother people.
