Why can't the mobile phone receive information?

It may be that the mobile phone is in arrears and cannot be received.

The position signal difference is not received.

Set blacklist or information interception function.

Solution:

First, mobile phone arrears

This is the most basic question. At present, mobile phones are generally rated by credit. The higher the credit rating, the greater the amount that can be owed. Credit rating is linked according to whether the payment is timely or not. Now that I owe money, I won't directly disconnect my mobile phone and SMS function. So when you can't get a text message, it's usually caused by the arrears of your mobile phone.

Second, the location is remote

In tunnels, tunnels, deep mountains or sparsely populated places, the signal is generally poor, and mobile phones can't receive short messages. Or other places, but the instrument with signal shielding shields the cell phone signal, so it is temporarily unable to receive information. Just change your location and go to a place with good signal, and you will naturally receive the information you didn't receive.

Third, set up a blacklist or SMS interception.

When you often receive spam or are harassed, you set up a blacklist or SMS interception, but sometimes you don't pay attention to it. Some settings in the setting options are not completely changed according to their own meaning, resulting in information being intercepted. You need to unblock the blacklist before you can receive SMS.
