It will only worsen the problem, and he will get angry at his parents and feel unfair. The child will feel that you don't trust him so much that you don't even give him a chance to prove otherwise. Besides, it's hard to understand that parents want what's best when all the kids around have smartphones and have fun at recess. This way, you will make your child an outcast among his peers. So my opinion is: you need to guide your child, to help him understand that the phone is not only for playing but also for learning and cognition. Don't impede him in learning about the world, if you don't want him to start hiding from you, using a fake phone number for verification australia.
