The GSM module need to be set the parameter before you begin to use it.
Or you also could try it with the sample code
What is your sketch you are using now?
The sample code?

Oh, the GSM module can't work without the sketch. you could follow the wiki page and set it step by step.
If you have any question, you could ask them here.
Anyway, your power supply is too strong. Although it could works now , it will heat up and kill the circuit in the long run.

Did you use an external power?
And which code you are using now?
Could you attach your hardware connection here?
