I have a GSM modem "Wavecom Q2303A". Can i send AT commands to it? If i can, how?(it will be a great help if someone post a small example).
I found nothing from google search, all of them are about gsm-shield but mine is not gsm shield.

If you do that you will be able to use Serial.print() to send commands over hardware Serial to the modem. However, you will need to disconnect it when uploading a program and you will not be able to use Serial.print to the Serial monitor for debugging.

Consider using SoftwareSerial to send commands to the modem which will avoid both problems. There are example programs in the IDE.
