Hi everybody!
Yesterday I started to work with the SIMCOM_SIM300 GSM/GPRS Modem. And I've coded a C program that sends a SMS. Everything is ok! I can send and receive SMS normally. But my question is: can I send a message to several numbers at the same time, just like our regular cell phones? If yes, could anyone tell me how to do that?
I've already looked at google and the SIM300D_ATC pdf with no luck.
I tried this: AT+CMGS="06755555555","06766666666"
but only the first cell phone (55555555) got the message.
Thanks a lot
