The difference between the Hong Kong version of BlackBerry 9900 and the Canadian version, please ask BlackBerry users to answer and seek the original answer ~ ~

The Canadian version of 1. is different from that of the customization company. The quality of the machine is the same. For example, the difference between custom machine Mobile and custom machine Unicom. The same is true for American versions such as att.t-mobile. But although it is the same in custom machine, the American att version is produced by four Mexican factories, with the best quality, and it is the only version that supports nfc and 4g networks.

As for the input method, don't worry that each version is just hardware. Chinese is determined by the system. Just install a system that contains Chinese. At present, the latest system comes with Chinese.

3. The flow varies from person to person. It depends on how much software is used. As for applications, it is less than ip and Android. But there are special versions of BlackBerry, qq, Weibo and so on.

4. It is recommended to buy conditional att, and it is a batch produced by 12. I heard it won't change.
