What should I do if my mobile phone can't receive the verification code?

If you are using an OPPO/ One Plus mobile phone, if you can't receive the verification code, you can refer to the following steps for troubleshooting:

1. A single software cannot receive the verification code.

If a single software can't receive the verification code, I suggest you compare other mobile phones to see if you 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 after backing up the data, and then restart the mobile phone to see if it can be restored.

3. If the above methods fail to solve your problem, please take the purchase invoice, warranty card and mobile phone to the nearest official OPPO service center for testing and handling.

2. Multiple or all softwares cannot receive the verification code.

1. The functions of harassment interception, blacklist and information interception have been turned on: you can try to turn off the functions of harassment interception, blacklist and information interception to see if you can receive the verification code.

Close the blacklist and harass interception:

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

(2) For the system models below Coloros11,enter "Settings >"; Security > harassment interception > click "blacklist/information interception" to turn off blacklist and harassment interception.

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

2. Harassment interception, blacklist, information interception and other functions are not enabled: if you have not handled the port number transfer service, I suggest you try to change your phone and card. If it is determined that it is a mobile phone card problem, it is recommended that you contact the operator to handle it. If there is a problem with your mobile phone, it is recommended that you bring the relevant purchase voucher to the nearest OPPO official service center for testing.

3. If the number portability service of an operator is handled recently, it will take some time for the SMS function to be activated. I suggest you consult the operator to confirm the specific effective time.
