Why does OPPO Cloud Service official website still have verification code restrictions? I need it urgently, so I can't receive the verification code.

If you don't receive SMS or verification code, it may exist in the following situations:

1, check whether the mailbox is full. If it is full, please delete some information;

2. If you still can't get it after deleting it, I suggest you change the machine or card to see if it is caused by hardware;

3. Check whether it is intercepted by mobile phone interception software;

4. Check whether the cell phone signal is normal and try to test whether it can be received in other places.

After the above reasons are eliminated, it still cannot be used normally. Please contact the local manual customer service to handle this problem. Some of the verification codes of OPPO mobile phones are not received, and some are received. Why? The mobile phone cannot receive the verification code. It is suggested to try the following operations: if the mobile phone can't receive the verification code, it can receive ordinary short messages, clean up the mobile phone system with the mobile phone housekeeper, and then shut down and restart, so that it can receive the verification code normally; If you can't receive the verification code and short message, you can call the customer service hotline of the communication operator to switch to manual operation, and consult the information parameter setting in detail, especially the information center number. Compare and observe the change of SIM card, and eliminate the abnormality of SIM card; Enter Settings-Application Management-Information, and click Clear Data; After backing up the important data files in the mobile phone, go to Settings-Other Settings-click Restore the mobile phone, or take the mobile phone to the customer service center for testing. The failure of sending short messages is generally caused by the wrong number of the information center, the arrears of the number, the abnormal reception and forwarding of the network base station, and the failure of the mobile phone. You can refer to the following methods to see if you can solve it:

1, consult the phone bill balance of the mobile phone card to see if there is any arrears;

2. Correct the information center number. First, check whether the information center number of "SMS-SMS Settings-Information Center Number Settings" in the mobile phone is correct (compare it with similar local cards or consult the operator to confirm the information center number);

3. Compare and observe the changes of SIM card and different time periods;

4. Try to restore the factory settings of the backup data (Settings-System "More"-Restore the factory settings, please do not check "Clear completely");

If the above methods fail to solve your problem, please take the purchase invoice, warranty card and mobile phone to the nearest OPPO customer service center for testing and handling. The user's own mobile phone number is blocked by the operator. You complained to the operator that this notification message was spam, which caused the message to be blocked by the operator. Solution: You need to contact the operator to solve this problem. 2. Blacklist settings such as SMS security software. You set strict interception rules in the text message. Solution: Check SMS blacklist settings, menu-> Harassment interception-> Settings, respectively, to see if there are numbers that do not allow SMS to arrive in interception mode and black and white list. Third, the privacy settings of the internal browser of the mobile phone. The security level of the browser is too high or the setting to block "third-party cookie and website data" is set. Solution: Reset the security level of the browser or turn off the setting of "blocking third-party cookie" in the browser, and set-> Privacy settings-> Content settings. Fourth, the number of short messages sent by your mobile phone exceeds the maximum limit of one day. In order to avoid short message bombing and waste of resources, some mobile phones set up a maximum of ten short messages per mobile phone number every day. Solution 5. Delay of network, wireless network, communication, etc. Due to network or geographical problems, there may be some delay in the authentication information sent by the server. Solution: Wait patiently, or try again after the countdown is completed: you can't log in to the service that needs to verify your mobile phone that day. Summary: 1. The mobile phone can't receive the verification code: 1, and the mobile phone is equipped with interception software. 2. The mobile phone is turned off, there is no signal for the time being, and it is overdue or stopped. 3. You can't receive sp message on the first day of recharging after the mobile phone is in arrears. 4. The user has set a blacklist on the operator side. 5. The mobile phone can't receive short messages of more than 70 words. 6. The mobile phone is used abroad or used overseas. 7. The SMS storage is full. 8. Mobile phone networks and operators have failed in some areas. 2. If you can't receive the SMS verification code, I suggest you check it first according to the above situation. You can refer to the following solutions: 1, unseal the SMS of the application software, or change a mobile phone. 2. Arrears for downtime are generally recovered within 24 hours after payment, and are basically recovered within 24 hours. I suggest you change your mobile phone number or pick it up the next day. 3. Contact the operator to cancel the blacklist. 4. If it is a signal network delay, you can try to get it later. Last one, maybe you wrote the wrong number.
