In Italy sales are not prohibited and possession of the jammers, but is prohibited from disturbing communications. Interpreting the law, the use of jammers is illegal then every time disturbs telecommunications.

hi, everyone. Our company locates in China and we mainly produce cellphone signal jammer. but I am wondering whether it is legal in your country. Does really the signal blocker can benefit people. many companies imported the mobile phone signal jammer from our company, especially in Germany, England, USA.....some use it for personal protection, some use it in army or prison, also in library, church where silence is expected.
what is your opinion about cellphone jammer? i want to know, thanks
