When does the soul send a message to a close friend?

It will be sent every once in a while.

This software will send messages to your close friends from time to time to push their advertisements and activities for you. In addition, if someone sends you a message, it will also give you a prompt, provided that you don't turn off the prompt function of this software. If you turn off the prompt function of this software, it won't pop up any more messages. If it is a SMS notification, it may be, because this software is registered with a mobile phone number.
