how to get internet with no phone line or cable?

clearwire

you can go to a cellular phone company and get a wireless card even tho they get kind of pricy. I know verizon and at&t have them

Well without telephone or cable infrastructure, you're basically left with WWAN aka Cellular internet. That is unless some other form of wireless ISP is available (like WiMAX)

Mostly WWAN is used on laptops by using a PC-Card or Express card device to provide a high bandwidth data channel over cell phone wireless infrastructure. There are routers that you can insert these WWAN cards into in order to share this cell internet connection with others on a LAN or to hook up a desktop

well you can get a wireless internet card, called an air card. the service usualy cost about $60 a month, and verizon has the best service
