I'm not sure what you mean? Wireless internet doesn't necessitate 3G or anything like that through a cell phone carrier. You can access the internet wirelessly just you with any other computer. The MBA's airport gives you access from any wireless internet in the area. If there isn't any wireless internet where you are, well, you can get an ethernet adapter and plug that in. Or you can buy a cheap wireless router for your home, and you can make your wired internet connection wireless.
