To change the mobile phone number of an Industrial Bank card, whether you hold a wealth management card (debit card) or a credit card, there are different steps:

For wealth management cards, first, You need to bring your ID card and bank card to any Industrial Bank branch in person. You can go to the counter to change the phone number reserved at the counter, or reset the mobile phone number bound to your personal online banking login password.

For credit cards, if the original mobile phone can still receive text messages, you can directly call the 95561 customer service hotline to modify the mobile phone number through manual service. If the original mobile phone cannot receive text messages, you need to go to the counter and bring your credit card, new mobile phone number and ID card to update.

For the SMS password of the wealth management card to be bound to a mobile phone number, during online banking operations, you must first confirm whether the registered mobile phone number is a new number. If so, use online banking to close the SMS password for the original mobile phone number, and then open a new number. If not, you must bring your ID card, financial management card and new mobile phone number to the counter to apply. If online banking prompts that the issuing institution or household address information is incomplete, this operation must also be completed at the counter.

The above information comes from the official personal finance online customer service of Industrial Bank. I hope it will be helpful to you.
