Connectivity — France
What travelers need to know about connectivity in France. What is legal at home can be a serious crime here — each rule links to its official source.
Connectivity in France: prohibited — what is legal at home can be a serious crime here.
France bans signal jammers outright, and the ban reaches merely HAVING one: importing, advertising, giving away or selling, putting into circulation, installing, POSSESSING and using any device meant to knock out radio equipment are all prohibited — so a jammer in your bag is an offence before you ever switch it on. Up to 6 months in prison and a EUR 30,000 fine. Separately, do not plug in the US-style mobile signal booster (repeater) you brought for a rural cottage or a camper: installing one without the prior authorisation of the mobile operators carries the SAME 6-month / EUR 30,000 penalty, and France's frequency agency handles roughly 150 of these cases a year. If indoor coverage is poor, use Wi-Fi calling — the agency says that needs no operator agreement.
Up to 6 months' imprisonment and a EUR 30,000 fine (Code des postes et des communications electroniques art. L.39-1) — the same penalty for an unauthorised jammer and for an unauthorised mobile repeater. ANFR agents are sworn and empowered to locate the equipment, identify the person responsible and draw up a proces-verbal.
