What is the failure of sending verification code? How to solve

Reasons and solutions for the failure of SMS verification code sending Generally speaking, there are four reasons for the failure of SMS verification code sending: (1) When websites/apps access SMS verification code service in the form of interface, they should set the content, frequency and effective time of SMS verification code reasonably, otherwise the sending failure may occur. 1. When customizing the SMS verification code template, the format and content should be standardized. For example, the signature content and text content cannot contain forbidden words, and there is only one signature. The correct format is Saicai Technology, and your verification code is 12456, which is valid within 60 seconds! 2. Set the acquisition times and effective time of SMS verification code reasonably to prevent it from being unusable due to too few acquisition times. Generally speaking, the reasonable setting is as follows: for users with the same mobile phone number or the same IP address, send 10 SMS verification code at most once a day, 2-3 times an hour, and the effective time varies from 3-5 minutes. (2) SMS verification code platform When users choose a cooperative SMS verification code platform, a reliable platform allows users to receive short messages in time. If they choose an unreliable platform, it will lead to the failure of sending! 1. Is the cooperation platform directly connected to the operator channel? Otherwise, sending SMS verification code may be delayed or failed. 2. Are there multiple backup channels configured? The main purpose is to prevent the surge of users' sending requests from causing congestion in the main channel of short messages and causing transmission failure in a short time. 3. Whether the interface is stable enough, because when the sending ratio is greater than the efficiency, there will be system crash, system error, and SMS verification code acquisition request failure. (III) Communication Operators Under normal circumstances, the SMS verification code is submitted to the communication operator after being reviewed by the SMS platform, and the communication operator will immediately send it to the user's mobile phone. However, when users are in the blind areas covered by network signals (such as basements and deep mountains). ), or in some areas where network signals are blocked, there may be cases where SMS verification code is not received. (4) It is also common that the receiver fails to receive the SMS verification code due to the receiver's reasons, as follows: 1, the mobile phone number is blocked by the SMS operator, and it needs to be released before it can receive the SMS verification code normally! 2. The current mobile phone number is in arrears or down, and the SMS verification code cannot be received! 3. The mobile phone security software intercepted it. In this case, the verification code could not be received. The above are the reasons and solutions for the failure of sending SMS verification code.
