How is the bill text message of Guangfa Credit Card sent to other mobile phone numbers?

There are several reasons why Guangfa Credit Card Bill SMS is sent to other mobile phone numbers:

1. The mobile phone number bound to the credit card account is inconsistent with the mobile phone number reserved by the bank. The mobile phone number reserved in the bank is different from the mobile phone number bound to the credit card account, and the bank will send the bill SMS to the mobile phone number reserved in the bank.

2. Credit card account information is stolen or fraudulently used by others, resulting in billing information being sent to other mobile phone numbers. This is because the credit card account was hacked or personal information was leaked.
