Why can't Sigou Education receive the verification code?

It may be a signal problem or a phone number owed or something.

Mobile phone number has now become one of the important means for major network platforms to strengthen network supervision, and SMS verification code has also become the main verification method of this supervision method! At present, verification code is supported by most websites for registration and login. It is its function that can effectively prevent malicious login and registration, and each verification code is different and can be excluded. Using other viruses or software to automatically apply for users and log in automatically can effectively prevent this problem.

1.APP platform's restrictions on the number of times users can obtain verification codes: each platform has restrictions on the number of times each mobile phone number can obtain verification codes every day. For example, an APP platform limits the number of times each mobile phone can get verification code to 10 times a day. If you have 10 times today, you can't get the verification code no matter how hot it is!

Solution: 1 You can contact the APP platform customer service and apply for the adjustment of the upper limit of the number of verification codes; 2, in the absence of special needs or circumstances, you can wait until the next day to try again;

Second, the mobile phone number itself does not support the operator's business in the current region: at present, basically all Internet platforms support the three major operators, but the mobile phone numbers in Tibet, Xinjiang, Hong Kong, Macao and Taiwan and overseas may be restricted by the current regional operators, resulting in the inability to handle business normally!

Solution: if you have to get the verification code, you have to change your mobile phone number; Of course, there are also the following special cases: some users with number portability will temporarily be unable to receive third-party short messages because the data interface is not synchronized in time. In this case, they have to call the corresponding platform or operator!

Third, SMS is intercepted by mobile phone security software: this is also very common. SMS messages on many platforms will be intercepted by the security software that comes with the mobile phone or the third-party security software that we installed ourselves, which makes it impossible for us to directly see the obtained verification code!

Solution: Open the security software, find the intercepted SMS or temporarily turn off the SMS interception function, and then try to get the verification code!

4. The SMS gateway is blocked or abnormal: usually, our mobile phone can receive SMS normally, but there are also special circumstances, that is, the SMS gateway is blocked or other abnormal conditions, which makes our mobile phone unable to receive SMS normally!

Solution: Wait a while, then try to get the verification code or contact the customer service of APP platform to solve it!

5. The mobile phone is abroad or uses an overseas mobile phone number: if the domestic mobile phone number is used abroad, it may be affected as long as it passes the platform verification code sent by the domestic operator; If you use a foreign mobile phone number, you will also encounter this situation!

Solution: It is recommended to change your mobile phone number and try again!

Seven. Unstable state of the mobile phone terminal: If it is a problem of the mobile phone itself, it may be a problem that the mobile phone terminal is unstable due to poor information, shutdown, downtime, out of service area, etc., resulting in the failure to receive the verification code or the failure to receive it.

Solution: Check the phone's own signal, whether it is turned off or not, and get the verification code again later.

Eight, the mobile phone number is blacklisted by the platform-the most common situation: in fact, many of the mobile phone numbers we use now have been used by others. If your mobile phone number is hacked by a platform before or during the use of several users, such as Tencent Video, then you will not be able to obtain the verification code of Tencent Video!

Solution: Call the corresponding platform to lift the blacklist restriction!
