GPRS/3G For SNAP PAC remote connectivity

Thanx that will be great i got my chart up and running to sms me if any problems or alarms goes off on the system now its just to send my sms’s to the unit to return me with the info using certain predefined commands! And my rx chart is also up and running now i just need to figure out how to append the string values from my probes, meters etc. when i send the commands to the unit. And i also want to send commands via sms to stop and start equipment we have on our system. And i am using a wavecom modem with sim card plugged into the R1 serial port A. So any ideas would help and wil go check out the site now!
