Do chores or odd jobs around the neighborhood, earn money, and buy your own phone and pay your own bill. Chances are that your parents really don't want to take the risk with you just yet. 13 and 14 year old kids aren't all that careful with their phones. I went through 5 phones in about 5 months when I was your age. Thank god for cell phone warranties. You can say you're going to do all these things but things might change if/when you get your way. Sometimes it's better to just stop begging and accept the fact that they aren't going to get you one. That's life. If you want a phone bad enough save your money and get your own. Phones are a lot of money.
