Receiving short messages from consumers for no reason.

There are two possibilities. One possibility is that someone used your mobile phone number before, and he reserved a short message service. This person did not go to the bank to change his mobile phone number in time after changing his number, which led to his business sending messages to this number all the time. Another possibility is that a customer directly left your mobile phone number by mistake when handling SMS business at the counter for the first time, which caused an oolong. In any case, the phone bill will not be deducted from your mobile phone. If you want to terminate this oolong business, you have to take your ID card to the bank, and the bank teller will cancel this business for you.
