Why is my mobile phone number in Anqing, Anhui? I called someone, and their cell phone showed that my cell phone number was abroad.

The version of the existing home directory is too old. It is recommended to upgrade to the latest version.

Also, because your side belongs to VoIP, you can set up VoIP to display foreign numbers.

If you are not at ease here, I suggest you go directly to the telecom business hall and ask the staff to help you look at the account problem.
