How did Huawei fail to send text messages?

Take Huawei P30 as an example, mobile phones can't send short messages. The specific reasons and solutions are as follows:

1. SMS center number is not set correctly. Please reset the correct number of the SMS center. For example, Huawei P30 mobile phone, after opening the mobile phone, enter the Information, More, Settings, Advanced and SMS Center in turn, and follow the interface prompts to operate the settings. It is recommended to check the instruction manual of the mobile phone.

2. If there is no signal or the signal is poor, you can go to a place with strong signal to test.

3. The mobile phone has turned off the short message sending function. You can turn on SMS and try again.

4. Being blacklisted by SMS, you need to go to the business hall to remove the blacklist status before you can use it normally.

5. The number balance is insufficient. You can pay the fee and try again.

6. There is something wrong with the mobile phone, so you can change the test.

It is suggested to put the SIM card on other mobile phones and try to send short messages to find out whether the SIM card is not authenticated by its real name, is in arrears, the short message service is closed by the operator, the short message center is set incorrectly, the signal is not good, or the network causes. If other mobile phones can't send SMS normally, I suggest you contact the operator to see if the service is limited.

This answer applies to most mobile phone models of Huawei.
