Can we directly use Call method to call the method of smart contract?

[0x7063]

I have a smart contract deployed on ropsten Test network.
So with the help of contract address I need to call the method of that smart contract deployed on ropsten Test network.
Can I do it by directly using the Call function?
Can you please provide a sample for the same.
