    Hi. Anybody knows if I want to connect the arduino and shield to the car’s battery, do I need an special circuit to protect the boards? or is enough with the voltage regulators that comes with both of them?.

    Hello, I have the SM5100B Arduino shell, but I am having some troubles with the at+cgact command. I am in Mexico and I make the connection through Telcel, some times the APN configuration works fine. But lately the at+cgact command takes a long time and returns “GPRS operation failure”. Does anyone have any idea about this problem?, I’m using the APN internet.itelcel.com. Thanks for your help.
    Another problem is, when I receive +SIND:11, I ask for the GPRS status, then I use at+cgatt?, and constantly I obtain 0, then if I do manually the registration with at+cgatt=1, the answer takes a long time, almost 90 seg. Some times the at+cgatt? returns inmediatly 1.
