Hi Everyone! I have a problem with GPRS Shield V1.2. I have it connected to an Arduino UNO. I'm trying to send a message and I can not.
I am following the instructions of http://www.seeedstudio.com/wiki/GPRS_Shield_V1.0. But, I can not send SMS. I do not know what I can do.
The sscom32E program Returns me this:
Call Ready AT+CREG?
+COPS: 0,0,"vodafone ES"
Can you help me?, please
