I explained India's point. It is for you to explain Chinese poit.
In addition, I can also tell you about the legal provisions of Chinese mobile phone operators.
China's mobile phone number is real name system.
According to Chinese law, the user must use the original and copy of his/her ID card to go to the business office of the mobile phone number operator to cancel his/her mobile phone number. The mobile phone number operator can only cancel the mobile phone number after one year of arrears.
This means that users who can cancel their mobile phone numbers must be living people.
BTW: Chinese mobile phone numbers are usually bound with numerous certificates and personal information. For example, bank card, graduation certificate, real estate certificate, network property, etc. If the mobile phone user dies or owes money, the mobile phone number operator will cancel the user, and those inheritors will go crazy.
