Why can't I receive SMS and verification code on my mobile phone?

If you can't receive SMS verification code by using OPPO mobile phone, the troubleshooting method is as follows:

1, to confirm whether the SMS function can be sent and received normally;

2. Whether the software requesting to send SMS verification code needs networking operation, and check whether the mobile phone can surf the Internet normally;

3. Whether the mobile phone is equipped with functions such as information interception and harassment interception. ;

4. Can I send and receive verification codes when trying to replace another normal SIM card?

5. Check whether other mobile phones can receive the verification code on the same software platform;

A. If other mobile phones can't receive the verification information, it is a problem with the software platform server;

B. If other mobile phones can receive the verification code, but their own mobile phones can't, and all the above steps have been checked, it may be the problem of the mobile phone itself. You can try to restore the factory settings (complete removal will lead to data loss, so it is recommended to back up the data before execution) or take the purchase voucher and mobile phone to the nearest OPPO customer service center for processing.
