I understand that there are roaming charges for calls that you make outside of your "area", but what about internet usage and google maps etc., are they subject to roaming as well??

Yes, absolutely.
Data roaming charges are typically VERY expensive... moreso than phone calls.
Be careful.

I'm guessing it would depend on your plan. I have unlimited data usage and i won't get charged when roaming. I'm with Sprint by the way.
