Why did I check the account balance in the online business hall, and the amount of arrears showed 0 yuan, but I received a text message saying that I owed money? !

If your number has a balance but is in arrears, it may be that the system did not deduct the phone bill in time, or your number balance is not enough to deduct the arrears. I suggest you pay attention and pay in time. If you have settled the arrears, but you are still in a state of arrears, I suggest you restart your mobile phone. If it is not solved after the operation, you can contact the manual customer service for processing.
