is information regarding 3G Kindle Personal Document fees:
Kindle Personal Documents Service Fees
Kindle Personal Documents Service doesn't charge fees for delivery of personal documents to Kindle devices over Wi-Fi or to supported Kindle reading applications.
Fees for the Kindle Personal Documents Service via Whispernet are based on the size of the file submitted (before compression if you use a .zip file), your country, and where you're accessing Whispernet. Personal documents service fees will only be charged for documents that are successfully delivered to your Kindle device via Whispernet. Personal documents service fees are rounded up to the next whole MB and apply to each personal document delivered via Whispernet to each Kindle device.
Note: You can also send your personal documents via e-mail as attachments to [name]@free.kindle.com. To have a document converted to Kindle format (.azw), the subject line should be "convert." Kindle Personal Documents Service will attempt to deliver your personal documents to your Kindle device via Wi-Fi when connected, and to the e-mail address associated with the Amazon account to which the device is registered. You can use the e-mail to download the file to your computer and transfer it to your Kindle device using a USB connection.

- For Kindle device users living outside the United States, the Kindle Personal Documents Service fee via Whispernet is $.99 (USD) per megabyte.
- Kindle Personal Documents Service is not available via Whispernet in Canada. Please see Transferring Personal Documents via USB for information about e-mailing personal documents to your computer for USB transfer to your Kindle device.
