I need to develop a robust app in vb.net without using any SMS gateway and GSM Modem. I have to use Nokia GSM Phone for sending SMS. For sending SMS, there are the ways I found while searching on the forum is
1. AT Commands
2. PC Connectivity Suite 3.0
3. PC Suite API 1.1
Now pls suggest me, what is the best option amongst the three?
What will be easy and robust way to develop the app in VB?
