Apple's mobile phone sends text messages so slowly.

Apple's iMessage message progress bar went very slowly and suddenly succeeded at some point. This is a unique phenomenon of Apple's mobile phone. The color of messages sent between Apple phones is different from that sent by Apple phones to Android system. There are two situations in which the mail shows that it has been sent but not read. First, you are indeed hacked by the other party (the phone can be connected, but the other party will not receive the ringtone. In the past, Apple tried personal mobile phones, but at present Apple mobile phones are not very clear). Another reason is personal habits.
