I've had my son on our family plan for five years. Yes, he has abused it at times. However, I feel that being able to control the cell phone gives us an advantage in monitoring his use and knowing here he is at. If he goes over on anything, he has to pay the difference. If he doesn't answer when we call, we take the phone. Any infringement on rules bore the consequence of losing the phone for a day, a week, or a month, and if he didn't have a phone where we could call him, he couldn't go out. He is now 18 and has a job. He must pay for his portion of the bill including he wanted unlimited texting and insurance. I am keeping a deposit in his bank account to cover any unwanted downloads. I also have gone in and programmed his phone to not allow him to download anything. I maintain a high amount of minutes but it's easier than getting stuck with a huge bill every once in awhile. Regarding texting, even if he keeps his use down, his friends (especially girls) are constantly texting him with messages like: "hi, what are you doing?" or "Call Me" or something like that. Every time they text it cost me too if he doesn't respond. I often thought of just getting him the call as you go but many of his friends had that and when they used up their minutes their parents could not locate them. Having him on our plan seems to work better.
