I haven't used the mobile phone number of Jingdong Finance. I just handled it. I received a text message and returned a white note.

At present, many mobile phone numbers have been used before, and then they were voluntarily cancelled, or they were cancelled by operators because of illegal acts, especially some old numbers. Platforms that provide credit services, such as JD Finance, will only have the mobile phone number registered by the user and the real-name authentication information when this mobile phone number is registered. They will only authenticate if the user is still using this mobile phone number. Therefore, for the collection system in JD.COM, your new mobile phone number is likely to be cancelled by the operator and sold to you. I suggest you call JD.COM's complaint customer service to explain this matter and ask them to untie it, otherwise it may bring you inconvenience in using Jingdong Finance or more financial inclusive services in the future.
