sim300 send text

I want to use sim300 to send message.
I know it can be used to send SMS,
but I want to know if it can be used to send Audio data.
If it can, how can I to use it for that. Thank you !
 

Yes,I mean that.
But now I think I may add one piece of audio chip to deal with it.
 

u just need to channel your voice data into sim300's MIC input.
 

hi
see sim300 hardware discribtion & at command in other topics to solve your problem
 

To transmit a short voice SMS on other modem (GPRS/GSM) we've simply used the MIC input. Short SMS was stored on ISD1400 chip.

Cheers
