I don't want that trump card, do I? Why do you always call me?

The king card you mentioned should be Unicom. Now mobile companies are doing activities and promotions. The king card is also more favorable. You can register first and get your card back for free in a few months. Cancel after expiration. You have nothing to lose. Of course, if you don't like it, you can definitely refuse them and ask them to stop harassing you by phone. Otherwise, you can complain to them.
