Where did you get it?

Did you not discuss this with your supplier before handing-over your cash?! 😮

I don’t know - what are your capabilities?

Are you familiar with ‘C’ programming for embedded devices?  
If not, you will need to learn that first.

Are you familiar with modems and GSM?  
Again, this is necessary background.

The best way to start would be to discuss your requirements with your local Distributor - they will be able to direct you to appropriate resources.
