Mobile phones are set to be prohibited in schools across England as part of the government’s plan to minimise disruption and improve behaviour in classrooms.

New mobile phones in schools guidance issued today (19 February 2024) backs headteachers in prohibiting the use of mobile phones throughout the school day, including at break times.

Many schools around the country are already prohibiting mobile phone use with great results. This guidance will ensure there is a consistent approach across all schools.

I suppose if enough countries do that sort of thing, pagers might start doing a comeback.

EDIT: Though looking at the wording, I’m not actually sure if this is a “we’re banning cell phones” or a “we’re talking about policies that make it look like we’re banning cell phones to keep the anti-cell-phone crowd happy”.
