Why can't the mobile phone receive the verification code?

If you use an OPPO mobile phone and can't receive the verification code, you can refer to the following methods:

1. If you can't receive the verification code of a single application, you can compare it with other mobile phones to see if you can receive the verification code normally. If other mobile phones cannot receive the verification code, it may be a service problem of the three-party application. You can contact the software side for feedback. If other phones can receive the verification code, you can try to uninstall the reinstalled software (application data will be lost), and then restart the phone to see if it can be restored. If you still can't recover, I suggest you go to the service center for testing.

2. If you can't receive multiple/all application verification codes, please confirm whether the mobile phone has the functions of harassment interception/blacklist/information interception. If it can be closed, try to see if it can be restored;

Note: If you need after-sales, please bring the purchase invoice, warranty card and mobile phone to the nearest OPPO customer service center, which will be tested and handled by professional engineers. Please back up and migrate your mobile phone data in advance before going (the safe and QQ WeChat data need to be backed up and migrated separately), and please contact the service center staff in advance to confirm the after-sales matters before going to the service center.
