Hi,
you can send and read the SMS using AT commands from terminals.
AT+CMGF=1 // to set TEXT mode
AT+CMGS=“mobile #” // to send text message
“text to be sent ”
AT+CMGR=1 //read message
AT+CMGL=“REC UNREAD” //List unread messages in text mode
if not, kindly provide some more detail info on what exactly you are looking for ?
Thanks and Regards,
Rex
