I would hope that if parents are planning on letting their child get a cell phone, first of all, they should take into consideration how much they can trust their child, second of all, set up rules for the child to obide by (obviously, if the rules cannot be adhered to, consequences must be set up) number three, (in my opinion) they should make sure it is a NEED rather than a desire. if it is just a desire (to be considered with it…)that may be a red flag.but you gotta know ur child (i’m sure that some children are good at keeping secrets, and their parents don’t know (yet) not to trust them, so that can be a problem, too)
personally, i got my cell phone right b4 HS because i was doing a lot that summer and my parents wanted to be able to keep in touch with me to make sure i was always ok. and my parents knew they could trust me (B”H!)
obviously, this is not good for some children
