Health Bao's mobile phone number can't be logged in, which may be because the network status is not good or the system is stuck. You can log out and close the background, and then try again. If the bound mobile phone number is changed, it is normal that the novice mobile phone number cannot log in. The mobile phone number is bound to my identity information, and it cannot be deleted or modified within 14 days. After the mobile phone number is changed, the old mobile phone number still needs to be declared within 14 days from the date of unbinding.
