„PISA 2022 results show that school phone bans appear to be effective in reducing distractions in class. However, on average across OECD countries, 29 % of students in schools where the use of cell phones is banned reported using a smartphone several times a day, illustrating that cell phone bans are not always effectively enforced.“
