What is the reason for the failure of sending value SMS verification code?

The reason why sending the value SMS verification code failed is:

1. Content problem: After editing the verification code SMS template, some enterprises do not pay attention to checking whether there are forbidden words or sensitive words in the SMS, and directly put the SMS containing forbidden words or sensitive words into the template, resulting in the SMS being intercepted and unable to be sent successfully. In addition, the company signature used in the enterprise short message is inconsistent with the company signature reported by the Ministry of Industry and Information Technology, which leads to the unsuccessful sending of the verification code short message. In addition, when users submit the verification code on the platform too many times, which exceeds the number limited by enterprises, it will also lead to the failure to obtain the verification code of SMS.

2. Platform problem: Part of the reason for the failure of sending SMS verification code is the channel problem of the third-party platform, which will also cause enterprises to delay or fail to send SMS verification code. If the channel of the third-party platform is not stable enough, when the number of users accessing the platform is too large to support the platform channel, it is very likely that the transmission will fail. In addition, there are cases where some enterprises lose the SMS verification code in the process. At this time, the enterprise can reissue it.

3. User reason: The unsuccessful sending of verification code is also related to the user. When an enterprise sends a verification code short message, if the signal of the user's location is not good, the user may delay receiving the verification code short message, which may also lead to the failure of reception. Or the user's mobile phone is turned off in arrears, and the interception setting is turned on. None of these reasons can make users successfully receive SMS verification code.
