Hi there. My name is*****'d be happy to hep you with this. Please give me just a moment to check the specs of your device.
Thank you for your patience. Although most Kindle Paperwhites are wifi only, certain models do have 3G. Please click the link below to access the user manual for the Kindle Paperwhite 3G. Do you see the symbol at the top of Page 11 on your Kindle indicating that it is connected to 3G?
Did you purchase your Kindle 3G from a wireless carrier or directly from Amazon? Has it been activated with a wireless carrier?
