maybe a good idea but it shows what has happened to parents who can;t even get their kids to reply to calls
I have 3 kids and I have told them that they need to have that phone with them and they need to answer it.
I have never had a problem with them though they also never get in trouble and do what is right.
I’m guessing you’ve taught them the meaning of “consequences”?
Our children get a phone when they’re old enough to sign up for it themselves (18) and pay for it themselves.
