GPRS Shield send/receive text

For a project I’m working on sending and receiving text messages to my Arduino Uno with a GPRS Shield V1.0. The end goal will be to parse the text, which will be an integer, turn an LED a specific color based on this value, and return an “OK” that it was received.
I have been following the Wiki verbatim to no avail. Partnered with this another I have been able to call to and from the GPRS shield as well as receive a text message. The only sketch on the Arduino is what is in the first tutorial the initial sketch.

Any help is appreciated greatly.

Maybe you have your own code,could you show it, we might have a try
