Eldest (15) daughters secondary school has a rule that you’re not allowed to use your phone at school, any being found with power on or used are confiscated – very fair
Youngest (12) daughters secondary school has a ‘no phones at all on school premises’ rule, which I think is unrealistic – if you’re working full time and trying to liaise around kids going to friends or after school clubs, or as with the other week everyone being sent home because of snow. I know most kids do have them, just keep them hidden.

More simple the phone, the better the battery life, and they always forget to charge them,
