France bans phones in all high schools, completing nationwide phone-free schooling from preschool to graduation

France promulgated a law on August 24, 2026 banning mobile phones and connected devices in all lycées (ages 15–18) from the new school year. Students must deposit devices in lockers on arrival. France already bans phones in primary and middle schools, making the school experience phone-free from maternelle through graduation. Unions call the timeline impractical.
