Hi,
I'm also in the same situation. I would also like to know if you've found a solution or if someone has one. Thanks
A lot is discussed on this thread but i'm still stuck at the looping' searching for network'.
Arduino UNO is on 12V + GSM arduino shield V2
SIM card and PIN are active
Network provider Koodo (Canada)
**The problem is most probably that my card is 3G (Bell and Telus) and not 2G (Rogers in Canada)
