My son is 12, will be 13 in just over 2 months. We just got him the 200 a month plan, which is what we all are on right now. Honestly, I am the one that is going to push us to the unlimited plan at this point. 
The reason we got DS a text plan is because I wanted to be able to text with him while he was with his dad for six weeks this past summer, and I just never canceled it. I like to be able to text with him, and so far I'm the only one he's allowed to text with. Well, that's not true - he could text with his dad, but so far they just don't. It's not a big deal to him at this point, as none of his friends text yet.

While she may not "need" texting right now by my 45yo standards, she thinks she needs it and she'll be thrilled.
