How Can We Read Incoming SMS by using Application in iOS

Question

In my application I am able to send an SMS programatically to a particular mobile number when the user clicks submit button. Then there is a response message from that mobi

Answer 1

Simply two words from Apple:

Not Possible

Detailed:

An iOS app can only access the data for which Apple supplies a documented public API. iOS can not access outside of the sandbox until Apple provides a public API for it. So intercepting/reading an incoming SMS not possible. And no idea when the iOS device is jailbroken.
