Hi,
We got our daughter a cell phone at 12 so she could always be in contact with us. We made her sign a contract stating certain rules such as it would never be turned on at school, that she would not lend it out, that she would never text, etc. About 10 rules in all. (I can send you the contract if you like). She's now 15 and has never broken the contract. It's for her safety. You can limit what she can do with the phone on AT&T such as no texting, no internet, etc. The Neon seems to be ok as long as she understands phones are fragile, no matter what type they are. You can also check online to see when she's using the phone (the call history for that number). My daughter knew we could see when and who she called or who called her, so she was careful to not use it when she wasn't supposed to. We gave her a set time to call her friends if she wanted to (like 1 hour at night) and she told her friends to NEVER call her except during that time cause we'd find out. So far so good. In this day and age it's almost required that they carry a phone for safety's sake. As long as firm rules are set down and she understands them, there should be no problem. Good luck.
