This video shows you how to communicate with TCP/IP socket using SIM900 GPRS AT Commands using a Hyper terminal kind of software. It shows you how to set up a connection to a server using a TCP/IP socket from SIM900 and also shows how to configure your Laptop/Desktop as a server using Socket test application which is available from SourceForge.net website.
You can also look at further articles on SIM900 at my blog www.raviyp.com.
I forgot to show you how to close the socket.
