Unicom failed to handle the micro-number display query.

Beijing Unicom's Woxiao service is developed and used normally. I suggest you try again another time in the future. If it doesn't work again, you can contact the local Unicom customer service for help.

The role of mini-speakers:

It is a virtual number that can be used to answer calls and send messages (limited to 10 per month, and receiving short messages is not affected), so that users can communicate with others without revealing their real numbers. The mini number itself does not depend on the SIM card, but it still needs to be bound to the SIM card, and all the expenses incurred are borne by the owner. The micro number itself no longer has any charging items, which is more economical than handling multiple mobile phone cards.
