Why does China Industrial and Commercial Bank 95588 always send short messages saying when you spend money on your card with the suffix XXXX?

Because the number you are using now is used by others before, he used this number to bind the account of ICBC. Although China Mobile or China Unicom will cancel the number, when others use the number, the bank will send a message to the number originally bound to the account, and this fee will be directly deducted from the bank card, so you don't have to worry. This is the case with the mobile phone number I am using now. My number is bound to CCB, and sometimes when I send a message, it will be blacked out directly.
