How to change the mobile phone number on the patent?

Do you have your mobile phone number on the patent? Generally, this number is only used to contact the patentee in China National Intellectual Property Administration. In 99.99% cases, China National Intellectual Property Administration will not call you. However, the patentee's mobile phone number does not appear in the patent certificate and the content published on the website, so I think it is of little significance to modify the mobile phone number.
