Okay ~ I have a monthly fee of $15 that comes out on automatic withdraw monthly. For my 3G service. My question is should I not have the automatic w/d set up ~ I think I don't use it all every month, but it renews anyway. Can I just use it all up and wait for the notice from AT&T, then buy more? I think I am getting more and still have a lot left. I am very sick ~ so this all may not make any sense. Forgive me!
