Mobile phone can't send text messages. What happened?

If the mobile phone can't send short messages, you can troubleshoot according to the following conditions:

In case 1, the number of the short message center is set incorrectly. Please reset the correct number of the SMS center. For example, Huawei mobile phone, after you turn on the phone, go to "Information-More-Settings-Advanced-SMS Center" in turn, and follow the interface prompts to operate the settings. It is recommended to check the user manual of the mobile phone.

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

In case 3, the short message sending function is turned off, so you can turn on the short message function and try again.

Case 4 is blacklisted by SMS and can only be used normally after going to the business hall to remove the blacklist.

In case 5, the number balance is insufficient, so you can pay and try again.

Situation 6: There is something wrong with the mobile phone, so you can change the machine for testing.

After the above reasons are eliminated, it still cannot be used normally. You can click on the feedback, and we will verify it as soon as possible.
