How to deal with Unicom's mobile phone trumpet?

Unicom mobile phone handling trumpet refers to Unicom's main and auxiliary card business. Users who handle the secondary card business need to bring the personal ID card of the head of household to the local China Unicom business hall, and the main card that opens the secondary card business must have real-name registration information. Supplementary card business cannot be handled through the online business hall, and the staff of the business hall need to be consulted for detailed charging package standards.

Users who successfully apply for the main card in the business hall of China Unicom can get a supplementary card with the corresponding number (the supplementary card number is different from the main card number, so users can't choose freely, and the staff will issue it). After receiving the secondary card, you need to activate the secondary card under the guidance of the staff in the business hall. Only the owner of the primary card has the right to apply for the opening of the secondary card business.
