My kids do not and will not have cell phones until they have an actual need for one. I have an old android phone with a pay as you go plan that I give them if they are going somewhere I can’t see them. When they get back it gets turned off and put back in a box until next time. All their friends have phones which they use for bullshit. I take pride in my children remaining unmolested. I know where they are and who they’re with and have talked to them honestly about what some sick people could try to do, how to spot grooming, how to handle situations of coercion or empty threats. Phones would only serve as a surface for attack in ways I can and can’t anticipate. Our kids are preyed upon and a phone is an attack vector. Their friends with phones are vaping, watching porn etc. when they are driving and working and doing well in their studies they can have a phone. Until then I have a house phone they can use to call their friends just like when I was a kid.
