Unable to activate imessage and Facetime of Japanese iPhone6 plus.

1. If you are a locked version of the machine, the push function of the mobile phone may not be turned on, resulting in the failure to successfully send the SMS to the Apple server. For example, your mobile phone can't push offline Fetion information. You can search for products like "Push" on Taobao, which is very cheap, around 5 yuan. Follow the steps to activate push successfully, and then try to activate imessage. 2. After activating the push function, turn on cellular data, turn on wifi (your environment must have unlimited Internet access), and turn on facetime and imessage switches in turn. 3. If all these methods fail, you can look at other methods on Weifeng. com。 In any case, you must activate the mobile phone push function first, otherwise other methods can't send international short messages to the Apple server.
