Lost my iphone and it has no internet/3G?

Help! I lost my iphone and I turned off 3G on it because I went over my data limit. Now when I try to find it on icloud, it won't show up because it says its offline. What do I do?

Added (1). How can I find it?

You don't. No connection to the internet, no way to use the internet to track it. So in the future, if a FEATURE is turned off, and said feature does not have a remote way to turn it off, said feature will not work.

Sorry but you'll probably never ever find it again. If I found your iPhone I would eject the SIM card, restore it in DFU mode, then jailbreak it so I can use it.

Report it stolen to your phone company. That way nobody else can use it. You won't get it back if someone tries to activate it but if you're not using something you paid for, then who else should?
