Send SMS

Hi everyone;
Cut story short I am trying to connect SIM900 to Mega ADK and send message.
I download the GSM/send sms from examlpes, I set the port & board right in the tools.
When I open serial port I see "SMS Messages Sender".
I wait to get the ready but nothing happens.
Could someone help me please.
Thanks
Maz

The libraries included with the IDE are for use with the official Arduino GPRS shield which is based on the Quectel M10, not the SIM900. Some exapmles may work, others may not.

If you need to use a library the try to find one for the SIM900.

Hi, thank you for the reply. I did not notice the difference. I will find a suitable library.
Thanks again
