What is 07 10- 10086? That's weird.

That's right. You use the number of Xiangfan, 07 10- 10086, which happens to be the local mobile KF of your card. If the new card user KF will call back to consult the user and ask him if he is satisfied with the service. If he is not a new card user, it can be an activity of KF to ask or confirm. You won't be the winner of any mobile company activities, hehe. Joke)
