sir how to make a simple modem with RS 200 and less to browse the internet i dont have cell phone sir?

First & very important point is - modem to surf internet is not a simple technology. Chips for this have not yet become so c-h-e-a-p. I am afraid you will have to wait for some more time.
Not possible. Sorry.

Why do you want to make one, and what do you mean by "RS 200"?
