hello this is my first post asking for help, usually i found everything what i need in other topics, but now i can't find a solution.
i bought a shield from aliexpress and im trying to make it work whit the tutorial from elecfreaks.com
http://www.elecfreaks.com/wiki/index.php?title=EFCom_GPRS/GSM_Shield#Step_1:_Creating_a_test_setup_for_the_GPRS_Shield
but is not working =(
is there a way to make it work whit the official arduino library? what things should i change to make this work? any idea?
Thnx
