The mobile phone card that binds Alibaba is lost. SMS authentication is required when logging in. Is there any way to change it?

Hello, in your situation, there is only one way. Just call Alibaba customer service, explain the situation to her, and ask to change the bound mobile phone. At this time, he will check some information with you, such as name, address and bound bank card number. He will ask a lot, so you'd better answer more. It doesn't matter if you forget individual data, but don't forget the most basic ones, otherwise you can't change them. I hope I can help you and wish you success. If my answer helps you, please accept it.
