Arduino Compatible GSM Module ICOMSAT v1.1 GPRS Not Working

Anyone please give me some advice .

I attached an ICOMSAT GSM Module to my arduino.
Basically i just started with the demo inside the arduino IDE
So the SendSMS demo worked well, but the TestGPRS one? Not working

I have plugged 4.5v power supply to the arduino and of course the packet data was working good as i have tested it on my phone.

And til now it keeps giving an error , as you can see in these attachments

So help me to solve this error please?
Thank you very much

You are using programs intended for use with the official Arduino GSM/GPRS shield, which uses the Quectel M10 chip, with a shield that uses the SIM900. There may be commands in there that are specific to the M10. You need to go through the code and check them.
