I think I may have found a good plan...

Here I am again asking for advice! I asked before about some advice for shopping for a cell phone. Now I am asking for advice about a cell phone plan. I think I may have found a good plan, but I can't be sure. The plan is called the Get More plan by T-Mobile. You get 600 whenever minutes and unlimited night and weekend minutes for $39.99 a month. To me it sounded like a good plan, but I am only 14 and yet I do understand most of what is explained, I don't understand all of it. Does this seem like a good plan to you all?? Thanks for all of your help!!

P.S. If your wondering why my parents aren't looking at plans for cell phones, it's because my parents don't understand it. My mom trusts me to find a good reasonable plan for my phone, and so as you can see, your advice is helping me alot!! THANK YOU!!
