Signal Jammer Device Policies In France

Related Laws of phone signal jammer blocker In France

　　Unlicensed phone signal jammer equipments in France are illegal in most cases. France's Postal and Electronic Communications Act (Code des postes et des communications électroniques, CPCE) prohibits individuals or organizations from using signal blocker jammers because these devices interfere with the operation of social order.

　　Certain institutions such as government departments, the military, and law enforcement agencies allow the use of signal jammer devices in certain circumstances, such as prisons, national examinations, and military operations. These exceptions usually require explicit permission from the French National Frequency Administration (Agence nationale des fréquences, ANFR). It is worth mentioning that France used un-ti drone signal jammer devices to maintain security at the 2024 France Olympis.
