Generally, I am not against pupils to bring their telephones to school, but only in case when they don't use them during lessons and just for immediate connection with parents, etc. Today, in most cases, children use smartphones for games and social media, also they often use devices for things such as buyessayclub service to ease their study process avoiding tasks that don’t want to do. Searching of some useful information, reading of reviews of essay service e.g. BuyEssayClub, using apps for studying - then it is considered to be ok. But, usually, pupils surfing Facebook, Instagram and so on, which can affect their progress in studies and communication skills. Because I think that school is a little society where people learn to live and communicate with each other.
