Question about my new Samsung Rant by Sprint?????

Sometimes when I try sending a message when I don't have service it tells me it will save my message in my "outbox". WTF!!! I have looked everywhere! I even read the packet! I don't understand. I have looked everywhere! Then sometimes it will randomly send my message saved in the outbox but some of them just don't send. But for the times it does send it doesn't even tell me it sent it!

By the way, if there is a zoom button for my camera could someone please explain where that is, too? Thanks in advance.
