The mobile phone number is my wife's. He has been dead for five years. Where can I change my name?

The mobile phone number is a real-name registration system and is handled with an ID card.

One ID card can handle two numbers, so. The mobile phone number cannot be renamed.

You may be talking about transferring, that is, transferring to your own name, or using the original number? Is that what you mean?

If so, you can bring your ID card to the business hall.

As long as the original number is transferred to your own name, the original number can continue to be used.
