The entered mobile phone number must be a mobile phone number in Chinese mainland, otherwise the binding cannot be completed.
The bound mobile phone number must be able to receive SMS verification codes, otherwise the binding cannot be completed.
The bound mobile phone number must be the mobile phone number of regular operators such as China Mobile, China Unicom, China Telecom, etc., otherwise the binding cannot be completed.
