I am using sim7000E with arduino uno and i want to be able to run it without a computer. I tried to connect it only with the power supply with the correct power and again it doesn't run my code. Does anyone know what i can do in order to fix it?

    again it doesn't run my code ... does that mean that it did not run the code before that? – jsotola Dec 20 '18 at 18:50
