A longtime ban on cellphones in New York City public schools has been lifted.
Mayor de Blasio had promised to overturn the ban during his 2013 mayoral campaign.
The change, which the city announced in January, went into effect Monday.
De Blasio called it "a common-sense action" that would give parents peace of mind.
Each school will have an individualized policy determined by its principal, with input from parents and teachers. It could include allowing student to use their phones during lunch or in designated areas and storing them in their backpacks during class.
The ban was put in place by former Mayor Bloomberg.
