Why can't Huawei mobile phone verification code be sent out?

If you are using a Huawei mobile phone and cannot receive the verification code message, please check it according to the following methods:

First, restart the network.

It may be that network delay or server communication delay makes it impossible to receive short messages. You can try to switch the flight mode and re-trigger the short message sending under the network.

Second, check whether the number is intercepted.

You can check whether it is set to block strange short messages and whether the number is included in the harassment interception blacklist. If yes, please turn off the function of intercepting strange short messages and remove the number from the blacklist if necessary.

Third, set the "information" application that comes with the system as the default application.

In order to protect your payment security and account security, the system prohibits third-party applications from obtaining the verification code SMS you received. It is recommended that you set the Information that came with your system as the default application and try again.

If you still need to use a third-party SMS application, please turn off the verification code protection function. The closing method is Information > Three Points > Settings > Verification Code Security Protection.

Fourth, if it is a mobile card and the enhanced information function is enabled, please switch to ordinary SMS.

Please switch the enhanced information to the general information interface: in the enhanced information chat interface, click the three points in the upper right corner > Switch to SMS/MMS.

5. Check whether the number is saved in the privacy space.

If you have ever created a private space, you can check whether there is any record of receiving text messages in the private space. If yes, please move the contact you need to the main space. After the contact is moved to the main space, you can view the short messages in the main space.

Sixth, restore the default setting operation.

Please restore the information to the default settings and try again. The path is as follows:

EMUI 9。 X and above: information > three points > settings > three points, and select to restore the default settings.

HarmonyOS system: information > four points >; Settings > four o'clock, and select to restore the default settings.

7. Check whether the SIM card can receive the verification code when it is inserted into other mobile phones.

Insert the SIM card into other mobile phones and check whether you can receive the verification code. If the communication of the third-party server is delayed, the verification code message may not be received. It is recommended to contact the operator or a third-party APP for processing.
