How to Use Whispernet on Your Kindle Paperwhite
If you have a Wi-Fi–only Kindle Paperwhite, all your documents will be delivered by Wi-Fi without charge. Otherwise, you might need Whispernet. This can help deliver your documents to you. If you are in an area where Wi-Fi is not available, your documents will be queued and delivered when Wi-Fi is available. If not, Whispernet it is.
If you have a 3G device and Wi-FI is not available, the document can be delivered using Whispernet — that is, over a 3G network. Amazon does not charge a monthly fee for 3G, but you do incur a charge for receiving documents this way. At present, the fee is $.15 per megabyte for customers in the United States and $.99 per megabyte when traveling outside the United States.
Wireless file transfer isn’t available in all countries. For the latest availability information, go to www.amazon.com/myk, log in if necessary, and click the Kindle Support link. Scroll down to the Wireless Delivery section. Even if wireless file transfer isn’t available, you can still use the Kindle e-mail conversion service and then transfer the converted files to your Kindle Paperwhite via USB.
You can set a limit on the charges allowed for personal documents to be transferred. Go to the Manage Your Kindle page, and click the Personal Document Settings link in the left column. Scroll down to the middle of the page to the section headed Whispernet Delivery Option. Choose Edit to change the maximum amount that you will be charged (from $0 to $49.50 with a default of $2.50).
If you try to convert a document that exceeds that charge, it won’t be delivered and you’ll be notified by e-mail. Some Kindle Paperwhite users set the limit at $0 to ensure that all personal documents are transferred via Wi-Fi and thus incur no charges.
