What is the reason why the verification code of the National Anti-Fraud Center cannot be received?

If you use a Huawei mobile phone, your device can't receive the verification code message. Please check according to the following methods:

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.

2. Check whether the number is in the blacklist.

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.

3. 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.

4. Enter the developer options to check the relevant settings.

Please go to Settings > System and Updates > Developer Options > Turn off the Don't Keep Alive switch in the application and set the Background Process Limit to Standard Limit.

5. Set the Information application attached to the system as the default application.

(2) If you still need to use a third-party SMS application, please turn off the protection function of the verification code. Closing method: information > three points > settings > verification code security protection.

6. Check whether to save the number to the privacy space.

7. Restore the default settings.

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

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