OK, I finally got it working after realising that I'd not changed the wire antenna for the larger circuit board one (i'm in the UK maybe that makes a difference). I'm just using a 5v FTDI interface for now and the terminal program called putty(free). I've wired Pin 2 = Ground, Pin 4 = 5v from FTDI, Pin 7 = FTDI Rx, Pin 8 = FTDI Tx, then loop Pins 1 & 14 to boot the board on power up (important to ground pin 14!). Put in a SIM (with no PIN required!). Connect FTDI to USB. After short pause one LED show be solid, second LED should be flashing. Start Putty, default speed was 115200 on Serial connect, for me COM3 (yours will be different). Type AT and press enter, response should be OK. then type these slowly, a few second pause between each commend: at - press enter OK at+cmgf=1 - press enter OK at+cscs="gsm" - press enter ERROR at+cscs="gsm" - press enter OK at+cmgs="07799xxxxxx" - press enter (the mobile number) > hello - press CTRL & Z together to signal send, enter does not work! +CMGS: 11 OK An SMS message should be sent
