South Korea has passed a bill banning the use of mobile phones and smart devices during class hours in schools - becoming the latest country to restrict phone use among children and teens.

The law, which comes into effect from the next school year in March 2026, is the result of a bi-partisan effort to curb smartphone addiction, as more research points to its harmful effects.

Lawmakers, parents and teachers argue that smartphone use is affecting students' academic performance and takes away time they could have spent studying.

The ban has its sceptics, including students, who question how it would work, its wider implications and whether it is addressing the root cause of addiction.

The bill passed convincingly on Wednesday afternoon, with 115 votes in favor out of 163 members present.

Most South Korean schools have already implemented some form of a smartphone ban. And they are not the first to do so.

Some countries like Finland and France have banned phones on a smaller scale, applying the restriction only to schools for younger children. Others like Italy, the Netherlands, and China have restricted phone use in all schools.

But South Korea is among the few to enshrine such a ban in law.

Children these days just can't seem to put their smartphones down, says Choi Eun-young, mother of a 14-year-old in Seoul.

It's not just children though. Nearly a quarter of the country's 51 million people depend on their phones too much, according to a 2024 government survey. But that figure more than doubles - to 43% - for those between the ages of 10 and 19.

More than a third of teens also say they struggle to control the amount of time they spend scrolling through videos on social media.

Some parents, like Kim Sun, whose two daughters are in primary school, are also worried about bullying on social media.

Cho Jung-hun, an MP from the opposition People Power Party who introduced the bill, emphasized the substantial scientific proof of the adverse effects of smartphone addiction on students' brain development.

While it only bans phone use during class hours, the law empowers teachers to oversee phone use on school premises, promoting education on responsible smart device usage.

The law includes exemptions for students with disabilities or educational needs, allowing assistive devices to be used.

Teachers are divided on the ban; while some support a firmer legal basis for restriction, others raise concerns regarding infringement on students' access to their devices.
