Dear all,

I have built a small SMS application running on
Windows 98 box using Nokia Card Phone 2.0, Nokia PC connectivity SDK 1.0 for Nokia Card Phone and Visual Basic 6.0

In this application user can send SMS to mobile phone. I am using a SIM card inserted in to the Nokia Card Phone for this purpose...
So When a person 'A', send a SMS to another person 'B', thru my application, my phone number only person 'B" will get...when that person 'B' reply back, I get SMS reply.i can trap it.but how do i know that this message is intended for person 'A'????

Your ideas and tips is more valuable for me.
Expecting your reply.

Thanks in advance
