GPRS MODULE

Hello,

I am from Portugal and i've bought a Arduino GPRS Module.
I've done some coding and tried all the examples available on the library but i can´t have signal on the board, there for, i can send or receive any messages.

I've have a project to use this module to start and stop a irrigation system by sending a message to the arduino.

Can you help me?

Thank you for your attencion.

Which one? Post a link to the manufacturer’s site, not some useless e-bay ad.

What library? The Black Diamond branch of the King County Library System does not have any GPRS examples in it.

but i can´t have signal on the board

What does this mean? Does the hardware work? If not, posting in the Programming section was not useful.
