Why can't the mobile phone number of Lubanjia platform be changed?

The mobile phone number placed on Luban's home platform cannot be changed for the following reasons.

1. The mobile phone number is the unique identification of the user. Each user needs to bind a mobile phone number when registering a Luban home account, and each mobile phone number cannot be changed when using this account in the future. Allowing the mobile phone number to be changed at will will bring account security problems, and it is difficult for subsequent users to identify and associate.

2. The mobile phone number is related to the follow-up push notification and other functions. Many functions need to interact with users through SMS verification code or telephone notification, which depends on the mobile phone number bound when registering. If you change your mobile phone number at will, the normal use of these functions will be affected.
