What is the reason why Huawei mobile phones can't send and receive short messages? How to solve it?

First confirm whether the mobile phone is in flight mode, and then contact the operator to check whether the mobile phone is down. After these two steps, you can basically detect whether it is a mobile phone problem or a sim card problem.

Mobile phone problem:

1. First enter the SMS settings.

2. Check whether there is any problem with the number of the SMS center. You can call the operator's customer service phone to inquire about the phone number of the local SMS center, or you can inquire online. If you still can't send SMS after setting it up, there should be something wrong with the SMS application of your mobile phone.

SMS application problems:

1. You can download third-party SMS applications, such as go SMS, Android SMS and so on.

2. If the problem still exists, please try to restore the factory settings. (If the mobile phone root has passed, it may be that the system is incomplete, so it is recommended to brush the machine. )

3. If the problem still cannot be solved, please take the mobile phone to Huawei for after-sales inspection and maintenance.

Enter the dial-up interface and enter "* # * # 4636 # * *" in quotation marks, which will automatically enter the mobile phone test (engineering) mode.

This mode has the following five options:

1. Mobile phone information,

2. battery information,

3. battery usage records,

4. Use statistics,

5. And WIFI information (wireless network situation).

(Note: Some mobile phones may be in English, but their locations are generally corresponding. )

After entering *#*#4636#*#*

1. Enter the mobile phone information, find the SMSC, and click Refresh.

2. After entering the project mode, click on the mobile phone information, and you can see all kinds of information of the mobile phone, including the current phone number, current network and so on.

What we need to do is:

1. Pull to the bottom of the screen and find the name marked "SMSC", followed by a blank input box.

2. Click the "Refresh" button, and the current SMS center number of your mobile phone will appear in the blank box.

3. Find the SMSC and click the refresh button to display the SMS center number/how to change it (13800 100500 is the SMS center number of Beijing Mobile).

If you can't receive SMS, or if you find that the SMS center number is incorrect after inspection, you need to change the corresponding SMS center number.

You can click on the input box, enter the correct number, and then click Update to complete the change of this number. Let's see if this is the case. If not, it is necessary to brush the machine.
