95588 sent me a text message saying how much money someone gave me the last number * * * * but my last number is not this number * * *! What's going on here?

This is because other customers remit money to this card through online banking, and then check the option of sending SMS to the other party's mobile phone number. Please check whether the bank card mentioned in the short message is your own. If so, please indicate the balance in check card. If not, just ignore it.
