Jammers

Since 1 January 2018, the importation and the possession of a jammer have been strictly prohibited in Switzerland as in the countries of the European Union. The rules applicable to these devices, also known as “blockers”, have therefore been made stricter, since previously the ban related solely to placing them on the market and using them. Because these jammers in particular prevent all communication by mobile telephone, they can represent a danger, since emergency calls are rendered impossible. Most of the time, advertising for this kind of device is misleading: it implies that their use is legal and takes care not to indicate that even their possession is illegal.
