Verification of SMS security code in rural commercial bank failed.

Next, let me answer this question for you.

SMS verification code has now become a standard in almost all industries on the Internet, and plays an important role in account registration, password modification, payment confirmation and so on. At present, the short message service of the third-party short message verification code platform is accessed through the short message verification code interface, and more than 99% users can basically receive the verification code in a few seconds, but there will be cases where a few users can't receive the short message verification code. So what are the common reasons why SMS verification code can't be sent or received? In general, the reasons for not receiving SMS verification code can be roughly analyzed from the following aspects:

It is common that the SMS verification code cannot be received due to user reasons, as follows:

1. User's mobile phone number is blocked by the operator. At this time, the user can call the operator to cancel.

2. When the user's mobile phone is in the blind area of signal coverage (such as deep mountains and plateau no man's land). ) or in areas where network signals are shielded (such as some areas of military sites, etc.). ), you may not receive the SMS verification code.

3. Intercepted by SMS interception software.

4. The user's mobile phone number is in arrears, turned off or stopped.

5. The user has set a blacklist in the mobile phone security software, and some mobile phone numbers are not allowed to send text messages to themselves.

6. Third-party SMS verification code platform reasons

Is the provided sms channel a direct channel for SMS operators? If not, the SMS verification code may be delayed or unable to be sent.

Whether there are multiple backup sms channel while providing the main sms channel, because it is unstable in sms channel and there is no backup channel, it is also easy to fail to send SMS.

Whether the interface of SMS verification code is stable enough, whether the interface technology supports high concurrency, whether there will be problems such as system crash, system error and failure of SMS verification code acquisition request when users visit a lot.

7. Either I didn't enter the correct mobile phone number, or my mobile phone number.
