Can the mobile card real-name registration system be changed to her husband's name?

The mobile phone number can be changed to a bound ID card. Generally, there are two situations:

1. The original mobile phone card without real-name registration system can go to the business hall of the local operator for real-name registration system, and you may need to provide relevant information, such as service password and first payment bill.

2. Mobile phone number transfer, that is, it was originally handled with someone else's ID card, which can be transferred to your ID card. This kind of transfer must require the original owner and the person who needs the transfer to carry the original ID card, and both parties go to the business hall where the number belongs to handle the transfer formalities together, and one party cannot handle it alone.

If there are other special circumstances, you can call the local operator's customer service hotline for help.
