We would really prefer your child NOT to bring a cellphone (or any other electronic devices) to school.
There are all sorts of problems associated with them, not the least of which is how often they get lost.
If you insist your child must carry one, then you and your child must take full responsibility for the safekeeping thereof.
Furthermore, they may not be used during school hours (8:00 – 16:15) at all and the teachers will confiscate them for a week (7 days) if they are seen being used.
If there is an urgent need for your child to use their phone during the day then they must ask for permission from a teacher.
*This policy includes smartphones and tablets.
