I'm boosting the battery voltage. As long the battery voltage is above 2.5V there will be no problems.
I see, that sounds like a nice idea. All Wifi and GPS blocks I know are relatively large, as they are meant for the breadboard. Still there have to be smaller ones in the market.

I'm not fully sure what do you mean by the small. SIM800L has relatively large size and it requires a micro-controller. I think you can find some smaller components than I used, but in the end it will be challenging to get everything into the 3310 case. And all the components should be compatible with each other.

I made this few months ago and then the zero was not available and now I would look towards that too. Nevertheless, the software I'm presenting here is compatible only with pi1 A and B.
