Hi
The code runs through the SMS part but I receive no SMS on my phone? How do I know that I have connection with the SIM908? I have GPRS on a "Sim908-C EVB v1.0 DESIGNED BY UNV" with no documentation. I don't know which connections to make. Like on yours I'm testing 7 and 8. TX to 7 and RX to 8. It docent work so I test the other way around... docent work!? I know the SIM908 have contact with the mobile net (blinks every 3 sec.) I only have GPRS TX and RX, GPS TX and RX and GND and VCC to connect to the Arduino.
Any ideas on what to do? I would be glad just to be able to send a AT command and get a response back.
Olle
