/*Note: this code is a demo for how to using gprs shield to send sms message, dial a voice call and
send a http request to the website, upload data to pachube.com by TCP connection,
The microcontrollers Digital Pin 7 and hence allow unhindered
communication with GPRS Shield using SoftSerial Library.
IDE: Arduino 1.0 or later
Replace the following items in the code:
1.Phone number, don't forget add the country code
2.Replace the Access Point Name
3. Replace the Pachube API Key with your personal ones assigned
You can’t perform that action at this time.
