Open the mobile App of China Construction Bank, click the menu sign in the upper left corner, find the security center, click Enter, select personalized limit setting, modify the limit, and click Modify.

It should be noted that when using an old mobile phone to log in to mobile banking, the system will prompt that there are two binding relationships. If you need to transfer money by new mobile phone later, please select Confirm Change; If you continue to transfer money through the old mobile phone, please choose to cancel the transfer. After the operation interval of 15 minutes is completed, the restriction of only binding the mobile phone will be automatically lifted.
