Can Unicom change its number?

If you are talking about the number change function of Tencent Wangka, this is a new service for users of Tencent Dawangka, Tencent Wangdika, Tencent Tianwang Card and Wang Xiaoka (music Wang Xiaoka, video Wang Xiaoka) to change their numbers independently. Users cannot change their numbers in the first month of activation, but they can change their numbers from the second month of activation, and they can choose to change their numbers every six months (including the current month). After the change is successful, the new number will take effect immediately and the old number will be invalid immediately.

Tencent wangka family card users can't handle the number change business.

You can change the number through China Unicom APP client-My Package Privilege Zone.
