Can I change my family number into a secondary card when I move?

According to the inquiry of China Mobile official website, China Mobile can change the family number into a secondary card, but it needs to meet some conditions.

1. First of all, I don't need to handle this process, but the agent can handle it in the local mobile business hall with both ID cards. When handling, it is necessary to provide the original ID cards of the users of the main card and the auxiliary card, and submit the copies of their ID cards (main card and auxiliary card).

2. Secondly, users who apply for a new supplementary card need to bring their ID cards to the local mobile business hall. When processing, the staff will get a new sub-card number, and the production fee including photo fee is 20 yuan. After handling the secondary card, you will receive an urgent business message. At this time, you can take your ID card to the business hall to activate the secondary card, and you can use it normally.

3. In addition, when handling the secondary card, you need to bring the ID card of the main card (owner) to the local mobile business hall. The staff will take a new sub-card number (that is, the same as the main card number), and the production fee includes the photography fee of 20 yuan. After handling the secondary card, you will receive an urgent business message. At this time, you can take your ID card to the business hall to activate the secondary card (which can be used as a secondary card).
