(ciao a tutti)
Hello! i'm using an arduinoUno board with a gsm Shield. I connected vcc and gnd, tx and rx. Sim is inserted. The leds status and pwr are static (so they are ok), while netlight continue to blink half and half (a short light and one second of pause.) I read that this signal means NOT CONNECTED. i don't know how make it ok! someone can help me?

I suggest you  try the TestModem program
The interest is to try if the modem of your shield is working properly
If it doesn't (as mine!) I am afraid it is hopeless...
