Ban use of Phone Blocking pouches in all schools across the UK please :)

Background

I understand the use of phone blocking pouches but it makes it alot harder to communicate with friends in other classes during break/lunch

Additional details

This would prevent students having to ask teachers questions in lesson e.g. French you only need a single word translated or your friend is in another form and lost their timetable and needs to ask you what lesson you have or can check themself etc.
