text: Try watching them more often to make shore they don't turn them on they should be aloud to bring them in but not aloud to use them at all. If you see someone use the phone take it from them and give it back at the end of the day. If they continue then take it and tell them if they don't stop they'll never get it back again. If the teacher can't stop it or if you can't tell the parent about it and talk to them. Tell them everything that has happened each day their child has used their phone. If their not satisfied they might take away the phone from their child and only allow them to use it when they are in need of help.
