My daughters, currently 9 and 12, have had their phones for 2 1/2 years now. We got them after the school sent them both on the wrong bus after school (not the same wrong bus either, 2 different wrong busses). We concluded that they needed the ability to get ahold of us at any given moment, so we got them both phones on our family plan (the phones were free, the charge is $5 per month per line). We initially programmed their phones with all the family phone numbers (us, grandparents, aunts & uncles cells) so that they would have the ability to reach someone if they needed an adult, we live within 1/2 mile of my entire extended family, so if they couldn't reach us at work, my parents or sister or brother would be able to get them. After loading the family contacts, we used the security lock to block incoming and outgoing calls from any numbers other than those in their contact lists, so didn't have to worry about them running up excess minutes, etc. Since then we have added texting to our family plan, and have added their friend's cell phones, to their contacts so they can call and text them too. They have both been very responsible with their phones as far as not using too many minutes, etc. My dh and I both have Android phones, so we have data/web, but the kids do not, and will not. Right now I am confident I can trust them not to access or download things they shouldn't, but I recognize that within the next couple years they might, if they had access, do so, and I don't want the responsibility of that, so all internet is blocked on their phones, and they will not be allowed to get an "upgrade" phone that has internet/data plan required.
