Why does the newly established Unicom always receive short messages from banks?

Because mobile phone number is a non-renewable resource, our company will reuse this resource. Please forgive me if the user has bound the related service before, which brings inconvenience to your subsequent use. This short message service is a service agreement between former users and banks. It is recommended that you contact the bank to cancel such notification service. Or you can go to China Unicom APP> service > handle > innovation zone > and set "harassment type setting" and "interception interception" in "mobile phone housekeeper".
