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 send a SMS thru my application, my phone number only he will get...when that person reply back, I get SMS reply..but how do i know that this message is intended for this person????
