If your settings about cellular (or mobile) data are properly set, and your iphone can connect to internet using a wifi network, then it could be a carrier issue. Contact your carrier and explain your problem, so that they can check your cellular data plan and help you (if you qualify).

Safari is a web browser. It is used to access content on the Internet. Saying that it doesn't work if you don't have Internet is like saying you car won't go anywhere if you don't start the engine...
