To purchase and send content, your Kindle device needs to be connected to a wireless network and registered to your Amazon Z.cn account. By registering an account, you can also transfer your purchases between Kindle devices and Kindle reading software.

If your Amazon account is your mobile phone number, you can directly register the Kindle with your mobile phone number. You can click my account, settings, address, address and mobile phone number (which should be the same as the mobile phone number used for login).

If you already have an Amazon Z.cn account: Click this option and enter your Amazon Z.cn account information. Click Register. After registration, your user name will be displayed in the upper left corner of the screen. If you don't have an Amazon Z.cn account: Click this option and follow the instructions on the screen to create a new Amazon Z.cn account.
