What is the power source? do you use a regulator (what's the name of it)?

I had some issues not like yours but somehow, in my project I use a LM317T and if my input voltage drops under 8.4V then the SIM908 doesn't have sufficient current and doesn't want to start.

Probably your issue is do to not enough current. You must have at least 1.5A.
