Hi Apart from using a phone, you can also use a microcontroller with GSM module and a microcontrolller; and using arduino would be simplest and fastest way to make a prototype, and also make replicate, since different phones have different command sets (I think) and pinouts(if available at all).
The arduino + GSM module way should cost around Rs. 2000: SIM900 module - example <http://www.ebay.in/itm/GSM-GPRS-SIM900A-Modem-Arduino-Compatible-With-Stub-Anttenna-and-SMA-Connector-/301276935108?pt=LH_DefaultDomain_203&hash=item46258133c4> Arduino/compatible board - freeduino <http://www.bhashatech.com/freeduino/265-freeduino-usb.html> Making the application with the GSM module should not be difficult. GSM module connects to arduino with a serial connection(RX,TX), and there are libraries already available to use with it. I am not sure but I think this will work http://arduino.cc/en/Reference/GSM, if not, its just commands you send send on the serial connection.
