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

Causes and solutions of mobile phone failing to receive SMS verification code

First, the number of acquisitions has reached the upper limit:

Each platform has a limit on the number of times each mobile phone number can get verification code 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: Only wait until the next day to try again!

Second, the mobile phone number itself does not support the carrier business in the current area.

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. SMS gateway is blocked or abnormal.

Under normal circumstances, our mobile phone messages can be received normally, but there are also special circumstances, that is, the SMS gateway is blocked or other abnormal conditions, which leads to our mobile phone not receiving SMS normally!

Solution: Wait a while, and then try to get the verification code!

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 domestic operators; 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!

7. Is there something wrong with the mobile phone itself or the mobile phone card?

If there is a communication failure in the mobile phone card or the mobile phone itself, it is easy to explain that the SMS verification code cannot be obtained!

Solution: Replace the mobile phone or re-insert the mobile phone card!
