This page is part of the Ministry of Internal Affairs and Communications' Internet Safety Guide for senior citizens. It addresses how to avoid troubles while using smartphones on public transportation. The guide recommends two solutions: enabling "Silent Mode" to mute notification sounds, or activating "Airplane Mode" to disable 4G/5G signals. Users are advised to check their smartphone settings beforehand to ensure they can always silence incoming calls and prevent disruptions in public spaces.
