Huawei mobile phone can't send text messages. What happened?

Huawei mobile phones cannot send short messages, and the following situations may occur:

SIM card has no real name. Please check whether the SIM card has passed the operator's real-name registration system registration certification. If the information when handling the SIM card does not match the ID card information, there may be problems such as abnormal signal, inability to talk, inability to send and receive short messages, and inability to access the Internet for data services. It is recommended that you consult the operator's customer service for real-name registration system certification.

Mobile phone arrears. Please check whether the SIM card is in arrears, and the suspension of arrears will affect the normal communication. Please check whether the SMS center number is set correctly. Please consult your local operator for details.

The short message is sent repeatedly. Please check whether the text messages are duplicated and sent to the same number, which causes you to be blocked by the operator. I suggest you consult your local operator.

The signal is not good. In the place where there is no signal or the signal is weak, the information may not be sent successfully. Please try again where the signal is strong.

The network is busy. The network system is busy, especially during the peak period of holiday information transmission, and the information may not be sent successfully. It is recommended to avoid the rush hour and try again. ?

Hardware error. Try to restore the default settings for SMS applications. Operation path: open the information, click > Settings, and select Restore Default Settings.

: mobile phone maintenance skills:

Protect the charging port: some responsible products will have special rubber protective covers, while others will not. If this part has a great influence on the mobile phone signal after contacting with some metals, it is necessary to keep the charging port clean.

Keep the magnet away from the phone: Keep the phone away from the magnet environment. The mobile phone speaker itself is magnetic, so don't let the mobile phone often touch places with a lot of iron powder, so as not to inhale too much iron powder from the sound hole of the mobile phone speaker and attach it to the speaker film, which will lead to the sound of the mobile phone receiver becoming smaller or even inaudible.

SIM card cleaning: Like other data contact surfaces, the metal contacts on the SIM card are very important. Careful protection against dust pollution and cleaning can delay its oxidation and prevent SIM card failure, sudden network interruption or screen display disorder. Generally speaking, its service life can reach more than 4 years. Unless you change your mobile phone frequently, normal dialing times will rarely hurt it. Some mobile phone cards have problems in design. Incorrect insertion can easily lead to scratches on metal contacts. Try not to use those mobile phones whose SIM cards are too tight.

Don't connect to the computer for a long time: When the mobile phone is connected to the computer, pay attention to the connection time, and don't let the mobile phone and the computer stay in communication for a long time to avoid switching on and off the computer repeatedly. When transferring files, you must consider and select the files to be transferred. It is best to complete the operation at one time, and it is best to exit the connection with the computer when the mobile phone is turned off.

Because the common COM data cable is not a plug-and-play interface, the voltage existing in the interface may affect the mobile phone. Of course, don't worry about the USB interface. On the other hand, don't disconnect when transmitting, which will also lead to incomplete data transmission and may not be deleted in the mobile phone, so you can only clean up the data media library comprehensively.
