After China Bank debit card swipes the card, does the mobile phone inform you whether to send a text message at any number or is there a special one?

Hello, now every bank provides a reminder service for the change of bank card balance, and this service is sent to users in the form of SMS, which generally includes: date, time, amount and part of the card number. The number of sending SMS is called SMS service number, which is a fixed number applied by each bank. If you receive a reminder message of balance change from another number, it must be a liar. Please pay attention to identification.
