Mobile phone arrears: this is the most basic problem. Nowadays, mobile phones generally evaluate the credit rating. If the credit rating is high, the amount in arrears will be larger, depending on whether the payment is timely linked to the credit rating. If you owe money now, you won't directly cut off the phone and SMS functions, so when you can't receive SMS, think about whether the operator sent SMS to urge you to pay the phone bill and didn't pay it.

Mobile phone setting problem: This situation is that a certain setting of the mobile phone is unexpectedly changed at a certain time, which makes the mobile phone unable to receive short messages. This situation may be that you have recently made personalized settings and changed some system settings, so go to the phone settings and click Backup Reset.
