It may be a very simple question but i need to ask before investing some amount in hardware.As i have read in this Arduino link , Arduino GSm shiled works pretty fine.My question is can we use any other GSM/GPRS module in place of Arduino GSM shiled and GSM library will work equally with that module also.
As per i know, GSM?GPRS module also workover serial protocol with any board, therefore we might use any GSM/GPRS module with TX/RX i.e. USART pin or any other digital pin if we are using serial software library over arduino ?
