I got my iphone hooked up yesterday, I have the 10 dollar 2500 texts a month one, I wanna check up on it so that i'm not going over the 2500 I wanna see like how many texts i have already sent, Where would I go to figure that out?

Yes I know that it's on the website, But I have been trying for an hour and cant get anywhere close ti what i'm looking for. And I'm on pay as you go.
