Oppo cannot receive the verification code.

If you are using an OPPO mobile phone (ColorOS system), if a single software cannot receive the verification code, it is recommended that you change your mobile phone and card to test whether other mobile phones can receive the verification code normally:

1. If other mobile phones can't receive the verification code, it may be a service problem of a third-party application. You can contact the corresponding software for feedback.

2. If other mobile phones can receive the verification code, it is recommended that you try to uninstall the reinstallation software, and restart the mobile phone after backing up the data.

If more than one or all software cannot receive the verification code, please check whether there is information interception, harassment interception, do not disturb, etc. Set on the receiver:

1. Blacklist closure and harassment interception:

(1) coloros11and above system models: enter "information >;" : "upper right corner harassment interception >": "upper right corner interception rule, and set it.

(2) the following system model 2)ColorOS 1 1+0: enter "Settings >; Security > harassment interception > click "blacklist/information interception" to turn off blacklist and harassment interception.

2. Turn off Do Not Disturb: Go to Settings > (Sound and Vibration) > Do Not Disturb and click Close.

3. You can also try the card replacement test to see if it is caused by the mobile phone card problem or the operator problem.

4. If you have already handled the number portability service, it will take some time for the SMS function to be activated and take effect. It is recommended that you consult the operator to confirm the specific effective time.
