Kindle Wireless Reading Device
Whispernet utilizes Amazon's optimized technology plus Sprint's national high-speed (EVDO) data network to enable you to wirelessly search, discover, download, and read content on the go.
Unlike WiFi, you don't have to find a hotspot. Amazon pays for Kindle's wireless connectivity so you will never see a monthly wireless bill for shopping the Kindle Store. There is no wireless setup—you are ready to shop, purchase and read right out of the box.
