Every day, the phone tied to the fund online is down. How to change a tie now?

You can log in to the online trading platform through My Account-Security Center to change the bound mobile phone, or you can modify it through My Account-Personal Information Management. If you don't receive the verification message, it is equivalent to losing your mobile phone. If you want to provide personal information (including name, original bound mobile phone number, ID number, associated bank card, etc. ), customer service staff will assist in rebinding the mobile phone number.
