I received a text message about someone else's account change. Can I just cancel it? Will it affect my own account?

Someone registered the wrong mobile phone number when processing the reminder message of balance change. You can't cancel it personally. If it is a CCB in the same city, you can go to the business hall to respond, and they will inform the card owner to replace it.

You can bring your valid ID card, passbook or debit card that needs to cancel or change SMS service to any counter of our bank, or through BOC self-service terminal (only debit card is supported, self-service terminal (excluding ATM equipment) operation steps: channel signing limit setting-SMS notification service), online banking (only non-inquiry online banking is supported, and computer login online banking operation steps: enter online banking user name and password to log in personal online banking-bank account-account SMS service) and online banking.
