What should I do if my mobile phone can't receive the verification code when I make an appointment for the driver's license test?

When making an appointment for a driver's license test, the mobile phone can't receive the verification code. The reasons and solutions are as follows:

1. There is a problem for no reason.

The mobile phone suddenly can't receive the short message, and you haven't done anything unusual on the mobile phone. This problem occurs, not because the mobile phone is broken, but because of a small problem on the operator's server and network delay, so call your mobile phone network operation business desk, such as Mobile 186.

2. The mobile phone is in arrears

The mobile phone generally evaluates the credit rating. If the credit rating is high, the amount of arrears will be greater, and the credit rating will be linked according to whether the payment is timely or not. Now that you are in arrears, you will not directly disconnect your mobile phone and SMS function. Therefore, 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.

3. Mobile phone storage is full

This situation is generally more common in non-smart phones, thinking that the storage of non-smart phones is generally limited, and many text messages are saved in the mobile phone card by default, while the storage capacity of the mobile phone card is small, so it is generally easy to be full. At this time, you need to delete some short messages or other things that occupy memory.

4. SMS center number setting

You can't receive the SMS, or there may be a problem with the number setting of the SMS center. For this problem, you can set the number of the SMS center correctly in the mobile phone information settings, and then confirm it to solve the problem. The specific method can refer to Baidu's experience.

5. The signal at the wrong location is poor

When you are in a tunnel, a tunnel, a deep mountain or a sparsely populated place, the signal is generally poor, and the mobile phone cannot receive the short message. Or other places, but the instrument with signal shielding has shielded the mobile phone signal, so it is temporarily unable to receive the information. Just change the location and go to a place with good signal, and you will naturally receive the message that you have not received.

6, mobile phone hardware/system problems

It is estimated that everyone does not want to brush the machine unless absolutely necessary, but it is very simple and can be solved in a few minutes. To put it bluntly, brushing the phone is to reinstall the system for the mobile phone, which is mainly aimed at the smart phone. If the above methods have not solved the problem, you can go to the mobile phone maintenance department for repair or replace it with a new one. For the sake of this experience, please refer to Baidu's experience "How to brush Android mobile phone (latest version)" for the detailed brushing tutorial.

7. Blacklist and information interception are set.

Nowadays, smart phones are more convenient, but some junk information often bothers users, so users have to set blacklists, but sometimes they don't pay attention. Some settings in the setting options are not completely changed according to their own wishes, resulting in information interception, so it is necessary to remove blacklist interception. For specific methods, please refer to Baidu's experience "How to pull out the blacklist of mobile phone address book".

8. Problems with mobile phone settings

This situation is that a certain setting of the mobile phone is accidentally changed at some time, resulting in that the mobile phone cannot 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 and Reset".

in the backup and reset window, click "Settings Reset", so that all mobile phone system settings will be returned to the factory settings, but no data will be lost. This can solve the problem, which is still an ideal situation.
