The Cell Phone Jammer is available in many designs and sizes. They are seen in small sizes similar to mobile phones as well as large as suitcases. The area a cell phone jammer can block signals depends on its size. Many important places are now fixed with cell phone jammers and have successfully stopped the nuisance of incessant calls and ringing tones which are highly disruptive to day-to-day work.
Personal usage of Cell Phone Jammers is illegal since it may violate freedom of communication. In addition, they can block security and emergency calls as well. Due to these reasons, importing, selling, buying and advertising of Cell Phone Jammers are illegal in many countries.
However, those who want them know where to find them. For example, in New York many people use them even in buses. They say that curtailing trash calls and loud ringing tones in public places should be done somehow. Even though such logics have some ground, blocking radio frequencies can cause greater damage than hearing ringing tones or bearing nuisance calls. It can stop emergency and security related calls putting many lives at high risk.
Therefore, illegal users of cell phone jammers have to pay a fine even though none have been got caught so far for using them.

The result is mobile users do not receive calls but a message ‘no signal' or similar one. They even would not know what is wrong with their mobiles.
However the purchase of cell phone jammers is possible online. Many websites display images of the latest mobile jammers and related details. A mini jammer can block frequencies of about 30 feet around a user. One can put a Cell Phone Jammer on a table and it would bock mobile frequencies around 30 feet creating a silence zone. Most persons cannot do their day-to-day work without mobiles now. Before long, the Cell Phone jammers will be equally as indispensable.
