What happened when Unicom sent a text message saying that it wanted to change the usim card?

If it refers to the function of changing the number of Tencent Wangka, it is a new service added by China Unicom to facilitate the users of Tencent Wangka to choose to change the number independently. You can choose to change the number every six months, and the new number will take effect immediately after the successful replacement, and the old number will become invalid immediately.

Tips:

1. After the change of the new number you selected takes effect, you cannot change it back to the old number;

2. In order to avoid the loss of your privacy and property, please unbind or change the binding information of the third-party platform in time before handling the number change business.
